Simultaneous tracking of spin angle and amplitude beyond classical limits | We show how simultaneous, back-action evading tracking of non-commuting
observables can be achieved in a widely-used sensing technology, atomic
interferometry. Using high-dynamic-range dynamically-decoupled quantum
non-demolition (QND) measurements on a precessing atomic spin ensemble, we

Charge exchange in galaxy clusters | Though theoretically expected, the charge exchange emission from galaxy
clusters has not yet been confidently detected. Accumulating hints were
reported recently, including a rather marginal detection with the Hitomi data
of the Perseus cluster. As suggested in Gu et al. (2015), a detection of charge
exchange line em... | 0 | 1 | 0 | 0 | 0 | 0 |
A Grazing Gaussian Beam | We consider Friedlander's wave equation in two space dimensions in the
half-space x > 0 with the boundary condition u(x,y,t)=0 when x=0. For a
Gaussian beam w(x,y,t;k) concentrated on a ray path that is tangent to x=0 at
(x,y,t)=(0,0,0) we calculate the "reflected" wave z(x,y,t;k) in t > 0 such that

Group actions and a multi-parameter Falconer distance problem | In this paper we study the following multi-parameter variant of the

Interacting fermions on the half-line: boundary counterterms and boundary corrections | Recent years witnessed an extensive development of the theory of the critical
point in two-dimensional statistical systems, which allowed to prove {\it
existence} and {\it conformal invariance} of the {\it scaling limit} for
two-dimensional Ising model and dimers in planar graphs. Unfortunately, we are

Online and Distributed Robust Regressions under Adversarial Data Corruption | In today's era of big data, robust least-squares regression becomes a more

Stable explicit schemes for simulation of nonlinear moisture transfer in porous materials | Implicit schemes have been extensively used in building physics to compute

Congruence lattices of finite diagram monoids | We give a complete description of the congruence lattices of the following

Motzkin monoid, and the partial Brauer monoid. All the congruences under

Weighted blowup correspondence of orbifold Gromov--Witten invariants and applications | Let $\sf X$ be a symplectic orbifold groupoid with $\sf S$ being a symplectic
sub-orbifold groupoid, and $\sf X_{\mathfrak a}$ be the weight-$\mathfrak a$
blowup of $\sf X$ along $\sf S$ with $\sf Z$ being the corresponding

Constraints on Quenching of $z\lesssim2$ Massive Galaxies from the Evolution of the average Sizes of Star-Forming and Quenched Populations in COSMOS | We use $>$9400 $\log(m/M_{\odot})>10$ quiescent and star-forming galaxies at
$z\lesssim2$ in COSMOS/UltraVISTA to study the average size evolution of these
systems, with focus on the rare, ultra-massive population at

Effect Summaries for Thread-Modular Analysis | We propose a novel guess-and-check principle to increase the efficiency of

Feldman-Katok pseudometric and the GIKN construction of nonhyperbolic ergodic measures | The GIKN construction was introduced by Gorodetski, Ilyashenko, Kleptsyn, and

Hamiltonian Monte-Carlo for Orthogonal Matrices | We consider the problem of sampling from posterior distributions for Bayesian

Rapid Mixing Swendsen-Wang Sampler for Stochastic Partitioned Attractive Models | The Gibbs sampler is a particularly popular Markov chain used for learning

Interferometric confirmation of "water fountain" candidates | Water fountain stars (WFs) are evolved objects with water masers tracing
