Lecture_21_Thomson_Scattering_NonCollective.txt
[SQUEAKING] [RUSTLING] [CLICKING] JACK HARE: So Thomson scattering-- as you remember, we set up the problem so that we had some scattering particle here. We had some incoming wave with a load of parallel wavefronts at some plane wave. It's got a wave vector Ki in the i hat direction here. We said that there was some or...

MIT_2267J_Principles_of_Plasma_Diagnostics_Fall_2023
Lecture_5_Refractive_Index_Diagnostics_I.txt
[SQUEAKING] [RUSTLING] [CLICKING] JACK HARE: Right, so today, we are going to start a series of several lectures on refractive index diagnostics. So these are diagnostics which use the fact that the refractive index of a plasma is not 1 in order to make measurements about the plasma. So first of all, what we're going t...
MIT_2267J_Principles_of_Plasma_Diagnostics_Fall_2023
Lecture_3_Magnetics_II.txt
[SQUEAKING] [RUSTLING] [CLICKING] JACK HARE: So I'm going to begin by giving a recap of the last lecture, just very briefly. And then we'll keep going with where we left off before. So you remember we talked about B-dot probes. These were little loops of wire, like this. They've got some area, A. They've got some magne...
MIT_2267J_Principles_of_Plasma_Diagnostics_Fall_2023
Lecture_11_Radiation.txt
[SQUEAKING] [RUSTLING] [CLICKING] JACK HARE: So today, we are starting a new topic, and we're going to be looking at radiation or self-emission from the plasmas. In a way, this is the natural language of the plasma. Previously, we have surrounded it with magnetic probes. We've plotted it with Langmuir probes. We've fir...
MIT_2267J_Principles_of_Plasma_Diagnostics_Fall_2023
Lecture_9_Refractive_Index_Diagnostics_V_Abel_and_Faraday.txt
[SQUEAKING] [RUSTLING] [CLICKING] JACK HARE: So we're going to go on to a slightly new topic today. We're going to be studying Abel inversion and then talking about Faraday rotation imaging. Does anyone have any questions on all the interferometry stuff we've covered so far before we leave that part alone? Everyone see...
MIT_2267J_Principles_of_Plasma_Diagnostics_Fall_2023
Lecture_1_Introduction_to_Principles_of_Plasma_Diagnostics.txt
[SQUEAKING] [RUSTLING] [CLICKING] JACK HARE: Let's talk a little bit about plasma diagnostics. So this very word, diagnostic, is pretty interesting. Gnostic here is coming from knowledge, and dia is a word sort of meaning through. So these are objects that we gain knowledge through. And we're trying to gain knowledge a...
MIT_2267J_Principles_of_Plasma_Diagnostics_Fall_2023
Lecture_17_Proton_Imaging.txt
[SQUEAKING] [CLICKING] [SQUEAKING] [RUSTLING] [CLICKING] PROFESSOR: So today we are going to be talking about proton radiography and proton imaging. So we're starting a series of three lectures in which we're looking at how to use particles as opposed to the plasma previously. You remember we used electromagnetic radia...
MIT_2267J_Principles_of_Plasma_Diagnostics_Fall_2023
Lecture_16_Line_Broadening.txt
[SQUEAKING] [RUSTLING] [CLICKING] JACK HARE: So just briefly, there was some discussion last time about Lyman sequence and the Balmer sequence and how these correspond to the K shell and the L shell. And I just looked this up, and I thought for your amusement and entertainment I would explain it. So the idea here is th...
MIT_2267J_Principles_of_Plasma_Diagnostics_Fall_2023
Lecture_14_Line_Radiation.txt
[SQUEAKING] [RUSTLING] [CLICKING] JACK HARE: Right. So we talked already about free-free radiation, bremsstrahlung, electron, cyclotron radiation. We talked a little bit about free bounds or recombination radiation. And these are all relatively simple compared to the complexity of bound-bound radiation, which is what w...
MIT_2267J_Principles_of_Plasma_Diagnostics_Fall_2023
Lecture_6_Refractive_Index_Diagnostics_II.txt
[SQUEAKING] [RUSTLING] [CLICKING] JACK HARE: OK, so you'll remember, in the last lecture, we discussed the technique called schlieren. And schlieren, we were relying on the fact that the plasma has refractive index gradients inside it which cause a deflection, and that deflection angle of the rays going through the pla...
MIT_2267J_Principles_of_Plasma_Diagnostics_Fall_2023
Lecture_8_Refractive_Index_Diagnostics_IV.txt
[SQUEAKING] [RUSTLING] [CLICKING] JACK HARE: So we talked about interferometry. We had some sort of plasma like this. And we had a probing laser beam that went through the plasma. And we split off a fraction of that probing laser beam and sent it around the plasma, which meant that when the two beams recombined, we got...

20_Roths_theorem_III_polynomial_method_and_arithmetic_regularity.txt
YUFEI ZHAO: For the past couple lectures, we've been talking about Roth's theorem. And we showed-- so we saw a proof of Roth's theorem using Fourier analytic methods. And we saw basically the same proof but in two different settings. So two lectures ago, we saw a proof in F3 to the M And basically the same strategy, bu...

MIT_18217_Graph_Theory_and_Additive_Combinatorics_Fall_2019
25_Structure_of_set_addition_V_additive_energy_and_BalogSzemerédiGowers_theorem.txt
YUFEI ZHAO: For the past few lectures, we've been discussing the structure of set addition, and which culminated in the proof of Freiman's theorem. So this was a pretty big and central result in additive combinatorics, which gives you a complete characterization of sets with small doubling. Today, I want to look at a s...
MIT_18217_Graph_Theory_and_Additive_Combinatorics_Fall_2019
8_Szemerédis_graph_regularity_lemma_III_further_applications.txt
PROFESSOR: So we've been discussing Szemeredi's regularity level for the past couple of lectures. And one of the theorems that we proved was Roth's theorem, which tells us how large can a subset of 1 through N be if it has no 3-term arithmetic progressions. And I mentioned at the end of last time that we can construct ...

MIT_18217_Graph_Theory_and_Additive_Combinatorics_Fall_2019
17_Graph_limits_IV_inequalities_between_subgraph_densities.txt
PROFESSOR: We spent the last few lectures developing the theory of graph limits. And one of the motivations I gave at the beginning of the lecture on graph limits was that there were certain graph inequalities. Specifically, if I tell you that your graph has edge density one half, what's the minimum possible C4 density...
MIT_18217_Graph_Theory_and_Additive_Combinatorics_Fall_2019
3_Forbidding_a_subgraph_II_complete_bipartite_subgraph.txt
YUFEI ZHAO: All right. We are going to continue our discussion of extremal graph theory. Last time, we discussed what happens when we exclude a triangle or more generally a clique. And we wish to find a graph that maximizes the number of edges. And at the end of the lecture, I stated the theorem of Erdos-Stone-Simonovi...

11_Pseudorandom_graphs_I_quasirandomness.txt
PROFESSOR: So we spent the last few lectures discussing Szemerédi's regularity lemma. So we saw that this is an important tool with important applications, allowing you to do things like a proof of Roth's theorem via graph theory. One of the concepts that came up when we were discussing the statement of Szemerédi's reg...
MIT_18217_Graph_Theory_and_Additive_Combinatorics_Fall_2019
13_Sparse_regularity_and_the_GreenTao_theorem.txt
YUFEI ZHAO: Last time, we considered the relationship between pseudo-random graphs and their eigenvalues. And the main message is that the smaller your second largest eigenvalue is, the more pseudo-random a graph is. In particular, we were looking at this class of graphs that are d-regular-- they are somewhat easier to...
MIT_18217_Graph_Theory_and_Additive_Combinatorics_Fall_2019
6_Szemerédis_graph_regularity_lemma_I_statement_and_proof.txt
YUFEI ZHAO: We're about to embark on a new chapter in this course where I want to tell you about Szemeredi's graph regularity lemma. Szemeredi's graph regularity lemma is a very powerful tool in modern graph theory, developed back in the '70s. Today I want to show you the statement and the proof of this graph regularit...

2_Forbidding_a_subgraph_I_Mantels_theorem_and_Turáns_theorem.txt
YUFEI ZHAO: So the first topic that I want to discuss in this course is extremal graph theory. And in particular, there is a whole class of problems which have to do with what happens if you forbid a specific subgraph. Forbid a specific subgraph. And I ask you, what's the maximum number of edges that can appear in your...
MIT_18217_Graph_Theory_and_Additive_Combinatorics_Fall_2019
14_Graph_limits_I_introduction.txt
YUFEI ZHAO: So today we are going to start a new chapter on graph limits. So graph limits is a relatively new subject in graph theory. So as the name suggests, we're looking at some kind of an analytic limit of graphs, which sounds kind of like a strange idea because you think of graphs as fundamentally discrete object...
MIT_18217_Graph_Theory_and_Additive_Combinatorics_Fall_2019
16_Graph_limits_III_compactness_and_applications.txt
YUFEI ZHAO: So we've been discussing graph limits for a couple of lecturers now. In the first lecture on graph limits, so two lectures ago, I stated a number of main theorems.

5_Forbidding_a_subgraph_IV_dependent_random_choice.txt
YUFEI ZHAO: For the last few lectures, we've been talking about the extremal problem of forbidding a complete bipartite graph. So today I want to move beyond the complete bipartite graph and look at other sparser bipartite graphs. So we'll be looking at what happens to the extremal problem if you forbid a sparse bipart...

18_Roths_theorem_I_Fourier_analytic_proof_over_finite_field.txt
YUFEI ZHAO: OK. So let's get started. So we spent quite a bit of time with graph theory in the first part of this course, and today I want to move beyond that. So we're going to talk about more central topics and additive combinatorics, starting with the Fourier analytic proof of Roth's theorem. We discussed Roth's the...
MIT_18217_Graph_Theory_and_Additive_Combinatorics_Fall_2019
4_Forbidding_a_subgraph_III_algebraic_constructions.txt
YUFEI ZHAO: Last time, we started discussing the extremal problem for bipartide graphs. And in particular, we saw the Kovari-Sos-Turan theorem, which tells us that if you forbid your graph from having a complete bipartide graph, Kst, then you have this upper bound on the number of edges in your graph. So we gave a proo...
MIT_18217_Graph_Theory_and_Additive_Combinatorics_Fall_2019
23_Structure_of_set_addition_III_Bogolyubovs_lemma_and_the_geometry_of_numbers.txt
YUFEI ZHAO: OK, we are still on our journey to proving Freiman theorem. Right? So we've been looking at some tools for analyzing sets of small doubling. And last time, we showed the following result, that if a has small doubling, then there exists a prime. It's not too much bigger than a, such that a big subset of a, o...
MIT_18217_Graph_Theory_and_Additive_Combinatorics_Fall_2019
12_Pseudorandom_graphs_II_second_eigenvalue.txt
YUFEI ZHAO: All right. Last time we started talking about pseudorandom graphs, and we considered this theorem of Chung, Graham, and Wilson, which, for dense graphs, gave several equivalent notions of quasi-randomness that, at least the phase values, do not appear to be all that equivalent. But they are actually-- you c...
MIT_18217_Graph_Theory_and_Additive_Combinatorics_Fall_2019
26_Sumproduct_problem_and_incidence_geometry.txt
YUFEI ZHAO: Today we want to look at the sum product problem. So for the past few lectures, we've been discussing the structure of sets under the addition operation. Today we're going to throw in one extra operation, so multiplication, and understand how sets behave under both addition and multiplication. And the basic...
MIT_18217_Graph_Theory_and_Additive_Combinatorics_Fall_2019
21_Structure_of_set_addition_I_introduction_to_Freimans_theorem.txt
YUFEI ZHAO: All right, today we're going to start a new topic an additive combinatorics. And this is a fairly central topic having to do with the structure of set addition. So the main players that we're going to be seeing in this chapter have to do with, if you start with a subset of some obedient group under addition...

9_Szemerédis_graph_regularity_lemma_IV_induced_removal_lemma.txt
YUFEI ZHAO: We've been spending the past few lectures discussing Szemeredi's Regularity Lemma. And one of the first applications that we discussed of the Regularity Lemma is the triangle removal Lemma. So today, I want to revisit this topic and show you a strengthening of the Removal Lemma for which new regularity tech...
MIT_18217_Graph_Theory_and_Additive_Combinatorics_Fall_2019
15_Graph_limits_II_regularity_and_counting.txt
[SQUEAKING] PROFESSOR: Last time, we started discussing graph limits. And let me remind you some of the notions and definitions that were involved. One of the main objects in graph limits is that of a graphon, which are symmetric, measurable functions from the unit squared to the unit interval. So here, symmetric means...
MIT_18217_Graph_Theory_and_Additive_Combinatorics_Fall_2019
22_Structure_of_set_addition_II_groups_of_bounded_exponent_and_modeling_lemma.txt
YUFEI ZHAO: The goal for the next few lecturers is to prove Freiman's theorem, which we discussed last time. And so we started with this tool that we proved called the Plunnecke-Ruzsa inequality, which tells us that if you have a set A now in an arbitrary abelian group, and if A has controlled doubling, it has bounded ...
