Topology with dynamical overlap fermions

We perform dynamical QCD simulations with nf = 2 overlap fermions by hybrid Monte-Carlo method on 64 to 83 × 16 lattices. We study the problem of topological sector changing. A new method is proposed

AN ALGORITHMIC APPROACH TO QUANTUM FIELD THEORY

The lattice formulation provides a way to regularize, define and compute the Path Integral in a Quantum Field Theory. In this paper, we review the theoretical foundations and the most basic

Dynamical fermions in lattice quantum chromodynamics

In dieser Doktorarbeit prasentiere ich Ergebnisse in Quantum Chromo Dynamik (QCD) mit dynamischen Fermionen auf dem Gitter. Die topologische Suszeptibilitat der QCD wird ausgerechnet, wobei dazu

Towards the Confirmation of QCD on the Lattice

Lattice Quantum Chromodynamics has made tremendous progress over the last decade. New and improved simulation algorithms and lattice actions enable simulations of the theory with unprecedented

Monte Carlo simulation of the dual representations for effective models of QCD at finite density

Lattice QCD is the most suitable tool to make quantitative predictions about nonperturbative phenomena of Quantum Chromodynamics (QCD), such as chiral symmetry breaking and the phase transitions at

Revisiting the hybrid quantum Monte Carlo method for Hubbard and electron-phonon models

A unique feature of the hybrid quantum Monte Carlo (HQMC) method is the potential to simulate negative sign free lattice fermion models with subcubic scaling in system size. Here we will revisit the

Avoiding ergodicity problems in lattice discretizations of the Hubbard model

The Hubbard model arises naturally when electron-electron interactions are added to the tight-binding descriptions of many condensed matter systems. For instance, the two-dimensional Hubbard model on

Lattice QCD simulations using the OpenACC platform

The OpenACC platform offers a directive based programming model for GPUs which avoids the detailed data flow control and memory management necessary in a CUDA programming environment and programs can be written in high level languages with OpenMP like directives.

Dynamical overlap fermions, results with hybrid Monte-Carlo algorithm

We present first, exploratory results of a hybrid Monte-Carlo algorithm for dynamical, nf = 2, four-dimensional QCD with overlap fermions. As expected, the computational requirements are typically

Alternative to domain wall fermions

We define a sparse Hermitian lattice Dirac matrix H coupling 2n+1 Dirac fermions. When 2n fermions are integrated out the induced action for the last fermion is a rational approximation to the

Localization in lattice QCD

In this paper, we examine the phase diagram of quenched QCD with two flavors of Wilson fermions, proposing the following microscopic picture. The supercritical regions inside and outside the Aoki
