Adiabatic axion-photon mixing near neutron stars
(Peer reviewed; Journal article, 2024) -
Chiral density wave versus pion condensation at finite density and zero temperature
(Journal article; Peer reviewed, 2018)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 ... -
Conformality loss and quantum criticality in topological Higgs electrodynamics in 2+1 dimensions
(Journal article; Peer reviewed, 2019)The electromagnetic response of topological insulators and superconductors is governed by a modified set of Maxwell equations that derive from a topological Chern-Simons (CS) term in the effective Lagrangian with coupling ... -
Curious case of the maximum rigidity distribution of cosmic-ray accelerators
(Peer reviewed; Journal article, 2023)In many models, the sources of ultra-high-energy cosmic rays (UHECRs) are assumed to accelerate particles to the same maximum energy. Motivated by the fact that candidate astrophysical accelerators exhibit a vast diversity ... -
Inhomogeneous chiral condensate in the quark-meson model
(Journal article; Peer reviewed, 2017)The two-flavor quark-meson model is used as a low-energy effective model for QCD to study inhomogeneous chiral condensates at finite baryon chemical potential μB . The parameters of the model are determined by matching the ... -
On-shell parameter fixing in the quark-meson model
(Journal article; Peer reviewed, 2017)The quark-meson model is often used as an effective low-energy model for QCD to study the chiral transition at finite temperature T and baryon chemical potential μB. The parameters in the quark-meson model can be found by ... -
Pion condensation and phase diagram in the Polyakov-loop quark-meson model
(Journal article; Peer reviewed, 2018)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 plane where μI is the isospin chemical potential. In particular, we focus on the ...
