astro-ph.HE astro-ph.GA
The Cygnus region of the Galactic plane contains many known supernova
remnants, pulsars, X-ray and GeV gamma-ray emitters which make it a prime
candidate for a Very High Energy (VHE) gamma-ray survey in the Northern
Hemisphere. Th... | arxiv topic:astro-ph.HE astro-ph.GA |
arxiv_dataset-1377907.5535 | Dissipative dynamics of a qubit coupled to a nonlinear oscillator
quant-ph
We consider the dissipative dynamics of a qubit coupled to a nonlinear
oscillator (NO) embedded in an Ohmic environment. By treating the nonlinearity
up to first order and applying Van Vleck perturbation theory up to second order
in the qubi... | arxiv topic:quant-ph |

Hamiltonian systems

In this paper, we consider the minimal period estimates for brake orbits of
nonlinear symmetric Hamiltonian systems. We prove that if the Hamiltonian
function $H\in C^2(\Bbb R^{2n}, \Bbb R)$ is super-quadratic and... | arxiv topic:math.DS math.CA |
arxiv_dataset-1379908.0129 | A stochastic min-driven coalescence process and its hydrodynamical limit
math.PR
A stochastic system of particles is considered in which the sizes of the
particles increase by successive binary mergers with the constraint that each
coagulation event involves a particle with minimal size. Convergence of a

GaAs/GaAlAs heterostructure and compare with predictions o... | arxiv topic:cond-mat.mes-hall cond-mat.stat-mech |
arxiv_dataset-1381908.0329 | On an Expansion Method for Black Hole Quasinormal Modes and Regge Poles
gr-qc
We present a new method for determining the frequencies and wavefunctions of
black hole quasinormal modes (QNMs) and Regge poles. The key idea is a novel
ansatz for the wavefunction, which relates the high-$l$ wavefunctions to null
geodes... | arxiv topic:gr-qc |
arxiv_dataset-1382908.0429 | The early evolution of the H-free process
math.CO
The H-free process, for some fixed graph H, is the random graph process
defined by starting with an empty graph on n vertices and then adding edges one
at a time, chosen uniformly at random subject to the constraint that no H
subgraph is formed. Let G be the random ... | arxiv topic:math.CO |
arxiv_dataset-1383908.0529 | Sub-Saturn Planet MOA-2008-BLG-310Lb: Likely To Be In The Galactic Bulge
astro-ph.EP astro-ph.GA
We report the detection of sub-Saturn-mass planet MOA-2008-BLG-310Lb and
argue that it is the strongest candidate yet for a bulge planet. Deviations
from the single-lens fit are smoothed out by finite-source effects and... | arxiv topic:astro-ph.EP astro-ph.GA |
arxiv_dataset-1384908.0629 | Constraints on background torsion from birefringence of CMB polarization
astro-ph.CO gr-qc
We show that a non-minimal coupling of electromagnetism with background
torsion can produce birefringence of the electromagnetic waves. This
birefringence gives rise to a B-mode polarization of the CMB. From the bounds
on B-m... | arxiv topic:astro-ph.CO gr-qc |
arxiv_dataset-1385908.0729 | Confluent operator algebras and the closability property

Certain operator algebras A on a Hilbert space have the property that every
densely defined linear transformation commuting with A is closable. Such
algebras are said to have the closability property. They are important in the
study of the tra... | arxiv topic:math.FA math.OA |

arxiv_dataset-1387908.0929 | Homomorphisms between Kaehler groups
math.AG math.DG
This is partly a survey and partly a research article. Some known results and
open problems about Kaehler groups (fundamental groups of compact Kaehler
manifolds) are discussed. A new notion of Kaehler homomorphism is introduced.
This is a homomorphism induced by... | arxiv topic:math.AG math.DG |

arxiv_dataset-1390908.1229 | On Batalin-Vilkovisky Formalism of Non-Commutative Field Theories
hep-th
We apply the BV formalism to non-commutative field theories, introduce BRST
symmetry, and gauge-fix the models. Interestingly, we find that treating the
full gauge symmetry in non-commutative models can lead to reducible gauge
algebras. As one... | arxiv topic:hep-th |

We have examined the impact of charged impurity scattering on charge carrier

Current rocket technology can not send the spaceship very far, because the
