An optimal quantitative two-scale expansion in stochastic homogenization of discrete elliptic equations [PDF]
, 2014 We establish an optimal, linear rate of convergence for the stochastic homogenization of discrete linear elliptic equations. We consider the model problem of independent and identically distributed coefficients on a discretized unit torus.

Advanced Functional Materials, EarlyView.Electric control of magnetic tunnel junctions offers a path to drastically reduce the energy requirements of the device. Electric field control of magnetization can be realized in a multitude of ways. These mechanisms can be integrated into existing spintronic devices to further reduce the operational energy.

Conformally Perforated Shellular Metamaterials with Tunable Thermomechanical and Acoustic Properties
Advanced Functional Materials, EarlyView.This study introduces Conformally Perforated Shellular Metamaterials (CPSMs), which overcome TPMS design limitations by mapping 2D cellular layouts onto 3D surfaces. CPSMs exhibit enhanced elastic stiffness, thermal conductivity, and acoustic performance compared to intact P‐type shellulars, demonstrating their potential as multifunctional ...

An extension of a theorem by M. I. Freidlin to good solutions to elliptic nondivergence equations
Le Matematiche, 1999 In the context of second order linear uniformly elliptic equations with measurable coefficients, a result of Freidlin [9], which deals with homogenization type properties for elliptic equations with smooth periodic coefficients, is extended to ...

Elliptic equations with discontinuous nonlinearities
Topological Methods in Nonlinear Analysis, 1993 The paper deals with the existence and nonexistence of positive solutions of nonlinear elliptic equations, with the nonlinear term discontinuous in the unknown function. The authors distinguish between 3 types of solutions. Topological methods -- specifically the degree theory -- are employed to obtain the existence of solutions, either in \(\mathbb{R}^

Formation of 2D Electron Gas at a Non‐Polar Perovskite Oxide Interface: SrHfO3/BaSnO3
Advanced Functional Materials, EarlyView.Through experiments and Poisson‐Schrödinger simulations, 2D electron gas formed at the non‐polar SrHfO3/BaSnO3 interface is observed. A large conduction band offset enables modulation doping by the intrinsic deep donors in SrHfO3, resulting in carrier confinement in BaSnO3 without relying on interfacial polarization or termination‐layer engineering ...

New series of 3D lattice integrable models
, 1993 In this paper we present a new series of 3-dimensional integrable lattice models with $N$ colors. The case $N=2$ generalizes the elliptic model of our previous paper.

On Fundamental Solutions of Elliptic Equations [PDF]
Proceedings of the American Mathematical Society, 1961 In this paper we prove: Let L be an elliptic operator in (x, t) with constant coefficients, the coefficients of the lower derivatives being zero, and let Lo be the operator obtained from L by deleting all the terms involving t-derivatives. Let K(x, t) be a fundamental solution of Lu = 0.
