Simulation of 3+1D glasma in Milne coordinates I: Development of the framework
Hidefumi Matsuda, Xu-Guang Huang
We propose a new numerical method for D glasma simulation using Milne coordinates. We formulate the classical Yang-Mills field and D classical color current on a lattice at…
Quark-meson model under rotation: A functional renormalization group study
Hao-Lei Chen, Zhi-Bin Zhu, Xu-Guang Huang
Rapid rotation may exist in physical systems such as non-central heavy ion collisions and neutron stars. Using functional renormalization group analysis of the quark-meson model, w…
Determination of impact parameter in high-energy heavy-ion collisions via deep learning
Pei Xiang, Yuan-Sheng Zhao, Xu-Guang Huang
In this study, Au+Au collisions with the impact parameter of fm at GeV are simulated by the AMPT model to provide the preliminary final-s…
QCD phase structure under rotation
Hao-Lei Chen, Xu-Guang Huang, Jinfeng Liao
We give an introduction to the phase structure of QCD matter under rotation based on effective four-fermion models. The effects of the magnetic field on the rotating QCD matter are…
Detecting Chiral Magnetic Effect via Deep Learning
Yuan-Sheng Zhao, Lingxiao Wang, Kai Zhou +1
The search of chiral magnetic effect (CME) in heavy-ion collisions has attracted long-term attentions. Multiple observables have been proposed but all suffer from obstacles due to…
Dynamic scale anomalous transport in QCD with electromagnetic background
Mamiya Kawaguchi, Shinya Matsuzaki, Xu-Guang Huang
We discuss phenomenological implications of the anomalous transport induced by the scale anomaly in QCD coupled to an electromagnetic (EM) field, based on a dilaton effective theor…
Kinetic theory with spin: From massive to massless fermions
Xin-Li Sheng, Qun Wang, Xu-Guang Huang
We find that the recently developed kinetic theories with spin for massive and massless fermions are smoothly connected. By introducing a reference-frame vector, we decompose the d…
Covariant Spin Kinetic Theory I: Collisionless Limit
Yu-Chen Liu, Kazuya Mameda, Xu-Guang Huang
We develop a covariant kinetic theory for massive fermions in curved spacetime and external electromagnetic field based on quantum field theory. We derive four coupled semi-classic…
Spin-dependent dynamically assisted Schwinger mechanism
Xu-Guang Huang, Hidetoshi Taya
We study electron and positron pair production from the vacuum by a strong slow electric field superimposed by a weak fast electric field pointing in an arbitrary direction as a pe…
Real-time dynamics of axion particle production due to spontaneous decay of a coherent axion field
Xu-Guang Huang, Dmitri E. Kharzeev, Hidetoshi Taya
We show that the coherent axion field spontaneously decays by emitting axion particles via quantum tunneling if axion potential has more than one minimum. By employing the -…
Spontaneous generation of spin current from the vacuum by strong electric fields
Xu-Guang Huang, Mamoru Matsuo, Hidetoshi Taya
We discuss spontaneous spin current generation from the vacuum by strong electric fields as a result of interplay between the Schwinger mechanism and a spin-orbit coupling. By cons…
Emergent QCD Kondo effect in two-flavor color superconducting phase
Koichi Hattori, Xu-Guang Huang, Robert D. Pisarski
We show that effective coupling strengths between ungapped and gapped quarks in the two-flavor color superconducting (2SC) phase are renormalized by logarithmic quantum corrections…
Transition radiation as a probe of chiral anomaly
Xu-Guang Huang, Kirill Tuchin
A fast charged particle crossing the boundary between the chiral matter and vacuum radiates the transition radiation. Its most remarkable features --- the resonant behavior at a ce…
Anomalous effects of dense matter under rotation
Xu-Guang Huang, Kentaro Nishimura, Naoki Yamamoto
We study the anomaly induced effects of dense baryonic matter under rotation. We derive the anomalous terms that account for the chiral vortical effect in the low-energy effective…

We study fermions in a magnetic field in a finite size cylinder. With the boundary condition for the fermion flux, we show that the energy spectra and the wave-functions are modifi…
Vector meson condensation in a pion superfluid

We revisit the suggestion that charged rho-mesons undergo Bose-Einstein condensation in isospin-rich nuclear matter. Using a simple version of the Nambu-Jona-Lasinio (NJL) model, w…
Analogy between rotation and density for Dirac fermions in a magnetic field
Hao-Lei Chen, Kenji Fukushima, Xu-Guang Huang +1
We analyse the energy spectra of Dirac fermions in the presence of rotation and magnetic field. We find that the Landau degeneracy is resolved by rotation. A drastic change in the…

Yin Jiang, Xu-Guang Huang, Jinfeng Liao
We show the existence of a new gapless collective excitation in a rotating fluid system with chiral fermions, named as the Chiral Vortical Wave (CVW). The CVW has its microscopic o…
