Analytic structure of nonhydrodynamic modes in kinetic theory
(Peer reviewed; Journal article, 2019-09)How physical systems approach hydrodynamic behavior is governed by the decay of nonhydrodynamic modes. Here, we start from a relativistic kinetic theory that encodes relaxation mechanisms governed by different timescales ... -
Anomalous low-temperature thermodynamics of QCD in strong magnetic fields
(Journal article; Peer reviewed, 2017-11)The thermodynamics of quantum chromodynamics at low temperatures and in sufficiently strong magnetic fields is governed by neutral pions. We analyze the interacting system of neutral pions and photons at zero baryon chemical ... -
Bayesian uncertainty quantification of perturbative QCD input to the neutron-star equation of state
(Peer reviewed; Journal article, 2023)The equation of state of neutron-star cores can be constrained by requiring a consistent connection to the perturbative Quantum Chromodynamics (QCD) calculations at high densities. The constraining power of the QCD input ... -
Competition of chiral soliton lattice and Abrikosov vortex lattice in QCD with isospin chemical potential
(Peer reviewed; Journal article, 2022-04)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 ... -
Lattice study of static quark-antiquark interactions in dense quark matter
(Peer reviewed; Journal article, 2019-05)In this paper we study the interactions among a static quark-antiquark pair in the presence of dense two-color quark matter with lattice simulation. To this end we compute Polyakov line correlation functions and determine ... -
Universal spacetimes in four dimensions
(Journal article; Peer reviewed, 2017-10)Universal spacetimes are exact solutions to all higher-order theories of gravity. We study these spacetimes in four dimensions and provide necessary and sufficient conditions for universality for all Petrov types except ...
