Oxygen Defect Formation Thermodynamics of CaMnO3: A Closer Look
physica status solidi (b), Volume 260, Issue 1, January 2023., 2023 The aim of this work is to find an optimal theoretical approach to compute the defect formation thermochemistry of CaMnO3. The hybrid functional PW1PW combined with CRYSTAL/PBE thermodynamic corrections is able to compute the defect formation enthalpy of CaMnO3 with an absolute deviation of −10.8 kJ mol−1 and can be recommended for use in computing ...

Spatio-temporal correlation functions in scalar turbulence from functional renormalization group [PDF]
The Physics of Fluids, 2021 We provide the leading behavior at large wavenumbers of the two-point correlation function of a scalar field passively advected by a turbulent flow. We first consider the Kraichnan model, in which the turbulent carrier flow is modeled by a stochastic ...

Sequences of Trees and Higher-Order Renormalization Group Equations [PDF]
, 2022 We define a notion of higher order renormalization group equation and investigate when a sequence of trees satisfies such an equation. In the strongest sense, the sequence of trees satisfies a $k$th order renormalization group equation when applying any choice of Feynman rules results in a Green function satisfying a $k$th order renormalization group ...

Functional renormalization group approach to the sine-Gordon model [PDF]
Phys.Rev.Lett.102:241603,2009, 2009 The renormalization group flow is presented for the two-dimensional sine-Gordon model within the framework of the functional renormalization group method by including the wave-function renormalization constant. The Kosterlitz-Thouless-Berezinski type phase structure is recovered as the interpolating scaling law between two competing IR attractive area ...

Ambipolar‐To‐Unipolar Conversion in Ultrathin 2D Semiconductors
Small Structures, Volume 3, Issue 12, December 2022., 2022 The applications of many 2D semiconductors have attracted considerable attention, but are severely limited by their ambipolar characteristics, which has sparked controversy about rethinking their potential. Thus, a comprehensive review is necessary for in‐depth understanding and to propose the optimum solutions for ambipolar treatment. Furthermore, the

Anti-Newtonian Expansions and the Functional Renormalization Group
Universe, 2019 Anti-Newtonian expansions are introduced for scalar quantum field theories and classical gravity. They expand around a limiting theory that evolves only in time while the spatial points are dynamically decoupled.

Analytic continuation of functional renormalization group equations [PDF]
, 2011 Functional renormalization group equations are analytically continued from imaginary Matsubara frequencies to the real frequency axis. On the example of a scalar field with O(N) symmetry we discuss the analytic structure of the flowing action and show ...

Ultracold atoms and the Functional Renormalization Group
Nuclear Physics B - Proceedings Supplements, 2012 We give a self-contained introduction to the physics of ultracold atoms using functional integral techniques. Based on a consideration of the relevant length scales, we derive the universal effective low energy Hamiltonian describing ultracold alkali atoms.

Nested Selves: Self‐Organization and Shared Markov Blankets in Prenatal Development in Humans
Topics in Cognitive Science, EarlyView., 2023 Abstract The immune system is a central component of organismic function in humans. This paper addresses self‐organization of biological systems in relation to—and nested within—other biological systems in pregnancy. Pregnancy constitutes a fundamental state for human embodiment and a key step in the evolution and conservation of our species. While not
