Universality of 2d causal dynamical triangulations [PDF]
, 2013 The formalism of Causal Dynamical Triangulations (CDT) attempts to provide a non-perturbative regularization of quantum gravity, viewed as an ordinary quantum field theory. In two dimensions one can solve the lattice theory analytically and the continuum limit is universal, not depending on the details of the lattice regularization.

Advanced Functional Materials, EarlyView.This study demonstrates the use of a low‐cost 3D printing technique to prepare a large‐area PVDF‐FAPbI3 composite dielectric film for flexible TENG application. The δ→α phase transformation of the FAPbI3 nanofillers has significantly improved the β‐phase content, morphology, and dielectric properties of the PVDF film.

Implementing the three-particle quantization condition including higher partial waves
Journal of High Energy Physics, 2019 We present an implementation of the relativistic three-particle quantization condition including both s- and d-wave two-particle channels. For this, we develop a systematic expansion of the three-particle K matrix, K $$ \mathcal{K} $$ df,3, about ...

Lattice String Field Theory [PDF]
PoS LATTICE2010:047,2010, 2010 String field theory is a candidate for a full non-perturbative definition of string theory. We aim to define string field theory on a space-time lattice to investigate its behaviour at the quantum level. Specifically, we look at string field theory in a one dimensional linear dilaton background. We report the first results of our simulations.

, 2002 Spin wave theory is applied to a quantum antiferromagnetic XXZ model on a triangle lattice in the presence of an in-plane magnetic field. The effect of the field is found to enhance the quantum fluctuation and to reduce the sublattice magnetization at ...

Switching of Magnetic Order via Non‐Magnetic Al Addition in FeCoNiMnAlx Films
Advanced Functional Materials, EarlyView.Non‐magnetic Al addition provides a sensitive handle to switch the magnetic order in high entropy FeCoNiMnAlx thin films via fcc to bcc phase transformation. Films with fcc structure exhibit a large exchange bias, while bcc films exhibit enhanced ferromagnetic properties, reflecting the magnetic ground state of Mn which switches from antiferromagnetic ...

Mass-improvement of the vector current in three-flavor QCD
Journal of High Energy Physics, 2018 We determine two improvement coefficients which are relevant to cancel mass-dependent cutoff effects in correlation functions with operator insertions of the non-singlet local QCD vector current. This determination is based on degenerate three-flavor QCD

Lattice Gauge Theory for a Quantum Computer [PDF]
PoS(LATTICE2019)112, 2020 The quantum link~\cite{Brower:1997ha} Hamiltonian was introduced two decades ago as an alternative to Wilson's Euclidean lattice QCD with gauge fields represented by bi-linear fermion/anti-fermion operators. When generalized this new microscopic representation of lattice field theories is referred as {\tt D-theory}~\cite{Brower:2003vy}.

A New Approach to Numerical Quantum Field Theory
, 1993 In this note we present a new numerical method for solving Lattice Quantum Field Theory. This Source Galerkin Method is fundamentally different in concept and application from Monte Carlo based methods which have been the primary mode of numerical ...
