On electric fields in hot QCD: infrared regularization dependence
Gergely EndrÅdi, Gergely Markó, Leon Sandbote
We study the impact of background electric fields on a hot plasma of charged particles -- a setting relevant for the early stages of heavy-ion collisions as well as laser pulse exp…
The axion-photon coupling from lattice Quantum Chromodynamics
Bastian B. Brandt, Gergely EndrÅdi, José Javier Hernández Hernández +2
Quantum Chromodynamics (QCD) is the theory of the strong interactions within the Standard Model of particle physics, which explains more than 99% of the mass of the visible Univers…
Quarkonium in non-zero isospin chemical potential environment at
Seyong Kim, Bastian B. Brandt, Gergely EndrÅdi
We study how the isospin asymmetry affects quarkonium states in QCD at near zero temperature. Using lattice Non-Relativistic QCD formalism, we calculate bottom quark correlators in…
QCD phase structure at finite isospin chemical potential and smaller-than-physical quark mass
Bastian B. Brandt, Volodymyr Chelnokov, Francesca Cuteri +1
Introduction of a nonzero isospin chemical potential in QCD leads to the emergence of a pion condensed phase at sufficiently large , bounded by a second order transition line…
Dense and magnetized QCD from imaginary chemical potential
Szabolcs Borsányi, Bastian Brandt, Gergely EndrÅdi +4
In this work, we computed the equation of state of dense QCD in the presence of background magnetic fields using lattice QCD simulations at imaginary baryon chemical potential. Our…
Pion condensation at non-zero isospin chemical potential with Wilson fermions
Rocco Francesco Basta, Bastian B. Brandt, Francesca Cuteri +2
In contrast to the case of non-zero baryon chemical potential, the isospin chemical potential does not introduce a sign problem and can be simulated on the lattice. When the isospi…
