Complex Langevin simulation of a random matrix model at nonzero chemical potential

Journal of High Energy Physics, 2018
In this paper we test the complex Langevin algorithm for numerical simulations of a random matrix model of QCD with a first order phase transition to a phase of finite baryon density. We observe that a naive implementation of the algorithm leads to phase

The glueball spectrum of SU(3) gauge theory in 3 + 1 dimensions

Journal of High Energy Physics, 2020
We calculate the low-lying glueball spectrum of the SU(3) lattice gauge theory in 3 + 1 dimensions for the range β ≤ 6.50 using the standard plaquette action.

Color confinement and random matrices. A random walk down group manifold toward Casimir scaling

Journal of High Energy Physics
We explain the microscopic origin of linear confinement potential with the Casimir scaling in generic confining gauge theories. In the low-temperature regime of confining gauge theories such as QCD, Polyakov lines are slowly varying Haar random modulo ...

Determination of the properties of vector mesons in external magnetic field by quenched SU(3) lattice QCD

Journal of High Energy Physics, 2017
We investigate the ground state energies of vector ρ ± and K ±∗ mesons depending on the magnetic field value in the SU(3) lattice gauge theory. It has been shown that the energy of a vector particle depends on its spin projection on the field axis.

lattice quantum field theories with quantum symmetry

, 1998
Quantenfeldtheorien in niederen Raum-Zeit-Dimensionen (kleiner als 4) zeigen das Phänomen der Quantensymmetrie, d.h. die globale (Eich-)Symmetrie läßt sich nicht mehr durch eine Gruppe beschreiben, sondern man benötigt allgemeinere allgebraische Objekte wie zum Beispiel Quantengruppen. In dieser Arbeit werden 1+1 dimensionale Gitterquantenfeldtheorien -

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

Walking, weak first-order transitions, and complex CFTs

Journal of High Energy Physics, 2018
We discuss walking behavior in gauge theories and weak first-order phase transitions in statistical physics. Despite appearing in very different systems (QCD below the conformal window, the Potts model, deconfined criticality) these two phenomena both ...
