ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.This study investigates the temperature‐dependent behavior of AlN piezoelectric crystal. Computational analysis reveals that the defect‐free AlN single crystal structure exhibited a stable piezoelectric coefficient d33 at 1300 K. Enhancing the stability of piezoelectric properties is essential for ensuring the reliability of high‐temperature ...

Dynamics of Dissipative Cavity Solitons in a Lattice Trap
Laser &Photonics Reviews, EarlyView.This work presents a generalized analytical model elucidating the dynamics of dissipative solitons in dual‐frequency‐pumped Kerr‐nonlinear cavities. The unified framework predicts new phenomena and expounds hitherto unexplained experiments covering hysteresis, Arnold tongues, and existence region of all‐optical dissipative time crystals.

Functional renormalization group and Kohn–Sham scheme in density functional theory
Physics Letters B, 2018 Deriving accurate energy density functional is one of the central problems in condensed matter physics, nuclear physics, and quantum chemistry. We propose a novel method to deduce the energy density functional by combining the idea of the functional ...

Functional Renormalization Group flows on Friedman-Lema\^{\i}tre-Robertson-Walker backgrounds [PDF]
, 2017 We reanalyze the construction of the gravitational functional renormalization group equation tailored to the Arnowitt-Deser-Misner formulation emphasizing its connection to the covariant formulation.

Global and microlocal aspects of Dirac operators: Propagators and Hadamard states
Mathematische Nachrichten, EarlyView.Abstract We propose a geometric approach to construct the Cauchy evolution operator for the Lorentzian Dirac operator on Cauchy‐compact globally hyperbolic 4‐manifolds. We realize the Cauchy evolution operator as the sum of two invariantly defined oscillatory integrals—the positive and negative Dirac propagators—global in space and in time, with ...

Quark Confinement and the Renormalization Group
, 2010 Recent approaches to quark confinement are reviewed, with an emphasis on their connection to renormalization group methods. Basic concepts related to confinement are introduced: the string tension, Wilson loops and Polyakov lines, string breaking, string

Functional renormalization group approach to the Kraichnan model [PDF]
Physical Review E, 2015 We study the anomalous scaling of the structure functions of a scalar field advected by a random Gaussian velocity field, the Kraichnan model, by means of Functional Renormalization Group techniques. We analyze the symmetries of the model and derive the leading correction to the structure functions considering the renormalization of composite operators
