Tailoring Robust Quantum Anomalous Hall Effect via Entropy‐Engineering

open access: yesAdvanced Materials, EarlyView.
Bandstructure renormalization, without (w/o) spin‐orbit interaction (SOI) (left) and with SOI (right), in the low‐energy Dirac bands of zero‐entropy (purple) and entropic (green) VCl3 monolayer (ML) with long‐range ordering (LRO). Abstract The development of quantum materials and the tailoring of their functional properties is of fundamental interest ...

Maximal abelian and Curci-Ferrari gauges in momentum subtraction at three loops

open access: yes, 2015
The vertex structure of QCD fixed in the maximal abelian gauge (MAG) and Curci-Ferrari gauge is analysed at two loops at the fully symmetric point for the 3-point functions corresponding to the three momentum subtraction (MOM) renormalization schemes ...

The three loop on-shell renormalization of QCD and QED [PDF]

open access: yes, 2000
We describe a calculation of the on-shell renormalization factors in QCD and QED at the three loop level. Explicit results for the fermion mass renormalization factor Zm and the on-shell fermion wave function renormalization constant Z2 are given.

The density-matrix renormalization group [PDF]

open access: yes, 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.

Advanced Thermal Interface Materials: Insights into Low‐Temperature Sintering and High Thermal Conductivity of MgO

open access: yesAdvanced Materials, EarlyView.
MgO has emerged as a promising candidate for improving thermal management in battery systems owing to its high thermal conductivity. In this study, it is demonstrate that the thermal conductivity of MgO is historically underestimated due to previously overlooked material behaviors.

Renormalization of the two-dimensional stochastic nonlinear wave equations [PDF]

open access: yesTransactions of the American Mathematical Society, 2017
We study the two-dimensional stochastic nonlinear wave equations (SNLW) with an additive space-time white noise forcing. In particular, we introduce a time-dependent renormalization and prove that SNLW is pathwise locally well-posed. As an application of

Spin‐Valley Polarization Control in WSe2 Monolayers using Photochemical Doping

open access: yesAdvanced Optical Materials, EarlyView.
A photochemical doping method is employed to modulate the spin‐valley polarization in WSe2 monolayers by tuning the carrier density from electron‐rich to hole‐rich regimes. This controlled doping enables a three‐fold variation in exciton polarization, revealing relaxation channels driven by scattering between excitons and charge carriers in two ...

A spatially periodic Kuramoto-Sivashinsky equation as a model problem for inclined film flow over wavy bottom

open access: yesElectronic 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 ...

A new method that automatically regularizes scattering amplitudes

open access: yesJournal of Physics Communications, 2023
We present a new regularization procedure called autoregularization . The new procedure regularizes the divergences, encountered previously in a scattering process, using the intrinsic scale of the process.

Jackson R. Herring and the Statistical Closure Problem of Turbulence: A Review of Renormalized Perturbation Theories

open access: yesAtmosphere, 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 ...
