Competition of chiral soliton lattice and Abrikosov vortex lattice in QCD with isospin chemical potential
(Journal article; Peer reviewed, 2022)We investigate the thermodynamics of two-flavor quark matter in presence of nonzero isospin chemical potential and external magnetic field. It is known that at sufficiently high isospin chemical potential, charged pions ... -
Quark and pion condensates at finite isospin density in chiral perturbation theory
(Peer reviewed; Journal article, 2020)I denne artikkelen vurderer vi to-smak QCD ved null temperatur og endelig isospin kjemisk potensiale μJegμI ved hjelp av en modelluavhengig analyse innen chiral forstyrrelsesteori i neste ledende rekkefølge. Vi beregner ... -
Reheating constraints on modified single-field natural inflation models
(Peer reviewed; Journal article, 2022)In this paper, we discuss three modified singlefield natural inflation models in detail, including Special generalized natural inflation model (SNI), extended natural inflation model (ENI) and natural inflation inspired ... -
Two-flavor chiral perturbation theory at nonzero isospin: Pion condensation at zero temperature
(Journal article; Peer reviewed, 2019)In this paper, we calculate the equation of state of two-flavor finite isospin chiral perturbation theory at next-to-leading order in the pion-condensed phase at zero temperature. We show that the transition from the vacuum ...
