Chiral density wave versus pion condensation at finite density and zero temperature
(Journal article; Peer reviewed, 2018-04)The quark-meson model is often used as a low-energy effective model for QCD to study the chiral transition at finite temperature T, baryon chemical potential μB, and isospin chemical potential μI. We determine the parameters ... -
Nonperturbative analysis of the electroweak phase transition in the two Higgs doublet model
(Journal article; Peer reviewed, 2018-11)We perform a nonperturbative study of the electroweak phase transition (EWPT) in the two Higgs doublet model (2HDM) by deriving a dimensionally reduced high-temperature effective theory for the model, and matching to known ... -
Pion condensation and phase diagram in the Polyakov-loop quark-meson model
(Journal article; Peer reviewed, 2018-10)We use the Polyakov-loop extended two-flavor quark-meson model as a low-energy effective model for QCD to study the phase diagram in the μI–T planewhere μI is the isospin chemical potential. In particular, we focus on the ... -
Scattering amplitudes of massive Nambu-Goldstone bosons
(Journal article; Peer reviewed, 2018-01)Massive Nambu-Goldstone (mNG) bosons are quasiparticles the gap of which is determined exactly by symmetry. They appear whenever a symmetry is broken spontaneously in the ground state of a quantum many-body system and at ... -
Thermopower in an anisotropic two-dimensional Weyl semimetal
(Journal article, 2020-01)We investigate the generation of an electric current from a temperature gradient in a two-dimensional Weyl semimetal with anisotropy in both the presence and absence of a quantizing magnetic field. We show that the anisotropy ...
