Renormalized entanglement entropy [PDF]
, 2016 We develop a renormalization method for holographic entanglement entropy based on area renormalization of entangling surfaces. The renormalized entanglement entropy is derived for entangling surfaces in asymptotically locally anti-de Sitter spacetimes in general dimensions and for entangling surfaces in four dimensional holographic renormalization ...

Exciton Dynamics in Layered Halide Perovskite Light‐Emitting Diodes
Advanced Materials, EarlyView.This review discusses the exciton dynamics in layered halide perovskitelight‐emitting diodes (PeLEDs). It opens with a summary of the structural and photophysical aspects, followed by an exploration of controlling dimensionality and cascade exciton transfer in quasi‐2D PeLEDs.

Atmosphere, 2023 The pioneering applications of the methods of theoretical physics to the turbulence statistical closure problem are summarised. These are: the direct-interaction approximation (DIA) of Kraichnan, the self-consistent-field theory of Edwards, and the self ...

, 2017 We compare the subtractive renormalization and the Wilsonian renormalization group approaches in the context of an effective field theory for the two-nucleon system. Based on an exactly solvable model of contact interactions, we observe that the standard

Advanced Materials, EarlyView.The rise of lead halide perovskite semiconductors has enabled high‐performance LEDs with internal quantum efficiencies approaching 100%. In order to further enhance the external quantum efficiencies limited by light outcoupling effects, in this account, the strategies for reducing energy dissipation through the substrate, waveguide, and evanescent ...

Hot exciton effect in photoluminescence of monolayer transition metal dichalcogenide
Natural Sciences, Volume 3, Issue 1, January 2023., 2023 The hot excitons (green circle) could be scattered into the light cone by absorbing or emitting acoustic phonon. This acoustic phonon assisted photoluminescence accounts for the non‐lorentzian high energy tail in the PL spectrum and the hot exciton effect is signaificant to linear optical properties of transition metal dichalcogenides.

Electronic Journal of Differential Equations, 2007 The spatially periodic Kuramoto-Sivashinsky equation (pKS) $$ partial_t u=-partial_x^4 u-c_3partial_x^3 u-c_2partial_x^2 u+2 deltapartial_x(cos( x)u)-partial_x(u^2), $$ with $u(t,x)inmathbb{R}$, $tgeq 0$, $xinmathbb{R}$, is a model problem for inclined ...

Gauge Theories on Deformed Spaces
Symmetry, Integrability and Geometry: Methods and Applications, 2010 The aim of this review is to present an overview over available models and approaches to non-commutative gauge theory. Our main focus thereby is on gauge models formulated on flat Groenewold-Moyal spaces and renormalizability, but we will also review ...

The density-matrix renormalization group [PDF]
, 2004 The density-matrix renormalization group (DMRG) is a numerical algorithm for the efficient truncation of the Hilbert space of low-dimensional strongly correlated quantum systems based on a rather general decimation prescription.
