High‐Throughput Discovery of Quantum Frustrated Materials
Advanced Functional Materials, EarlyView.Physics‐guided discovery of frustrated kagome and triangular magnets. ABSTRACT Geometrical frustration provides a fertile platform for realizing exotic quantum phases such as spin liquids, yet, the predictive identification of frustrated magnets remains limited.

Functional central limit theorems on Lie groups: A survey [PDF]
, 1998 The general solution of the functional central limit problems for triangular arrays of random variables with values in a Lie group is described. The role of processes of finite variation is clarified.

THE CENTRAL LIMIT THEOREM FOR UNIFORMLY STRONG MIXING MEASURES [PDF]
Stochastics and Dynamics, 2012 The theorem of Shannon–McMillan–Breiman states that for every generating partition on an ergodic system, the exponential decay rate of the measure of cylinder sets equals the metric entropy almost everywhere (provided the entropy is finite). In this paper we prove that the measure of cylinder sets are lognormally distributed for strongly mixing systems

Advanced Materials, EarlyView.ABSTRACT The accelerating expansion of data‐centric technologies is sharply increasing the energy burden of information storage, placing unprecedented pressure on the efficiency of magnetic switching. Conventional field‐driven reversal, once the foundation of magnetic memory, has become impractical in modern architectures due to its high energy cost ...

Advanced Materials, EarlyView.Uniform monolayer Cr2Ge2Te6 films are achieved on Si substrates by molecular beam epitaxy. Intrinsic ferromagnetism with perpendicular magnetic anisotropy is established in the films by anomalous Hall effect and superconducting quantum interference device measurements, albeit with strong magnetic fluctuations characteristic of its 2D nature.

An exponential inequality and strong limit theorems for conditional expectations [PDF]
Periodica Mathematica Hungarica, 2010 Let \((\Omega, \mathcal {A},P)\) be a probability space. Let \(A\in\mathcal {A}\) be a fixed event, \(P(A)>0\). Let \(P^A\) be the conditional probability measure with mean \(E^A\). Let \(\tau_i\), \(1\leq i\leq N\), be nondegenerated independent random variables with variance \(\sigma_i\), such that \(| \tau_i|

Advanced Materials, EarlyView.Stacked nanoflake assembly (SNA) membranes can oscillate autonomously, offering opportunities for soft actuation and energy harvesting. This work uncovers the physical mechanism behind the sustained oscillation of SNA membranes in gradient humidity and identifies three governing dimensionless parameters, enabling rational design for optimizing SNA ...
