Heavy-ion collisions at BNL's Relativistic Heavy Ion Collider and CERN's Large Hadron Collider provide strong evidence for the formation of a quark-gluon plasma, with temperatures extracted from relativistic viscous hydrodynamic simulations shown to be well above the transition temperature from hadron matter. How the strongly correlated quark-gluon matter forms in a heavy-ion collision, its properties off-equilibrium, and the thermalization process in the plasma, are outstanding problems in QCD… 

Effective Debye screening mass in an anisotropic quark gluon plasma

Due to the rapid longitudinal expansion of the quark-gluon plasma created in heavy-ion collisions, large local-rest-frame momentum-space anisotropies are generated during the system’s evolution.

The complex heavy-quark potential in an anisotropic quark-gluon plasma — Statics and dynamics

We generalize a complex heavy-quark potential model from an isotropic QCD plasma to an anisotropic one by replacing the Debye mass mD with an anisotropic screening mass depending on the quark pair

Multi-Species Thermalization Cascade of Energetic Particles in the Early Universe

. Heavy long–lived particles are abundant in BSM physics and will, under generic circumstances, get to dominate the energy density of the universe. The resulting matter dominated era has to end

Thermalization and prethermalization in the soft-wall AdS/QCD model

: The real-time dynamics of chiral phase transition is investigated in a two-flavor ( N f = 2) soft-wall AdS/QCD model. To understand the dynamics of thermalization, we quench the system from initial

Far-from-equilibrium kinetic dynamics of $\lambda \phi^4$ theory in an expanding universe

We investigate the far-from-equilibrium behavior of the Boltzmann equation for a gas of massless scalar field particles with quartic (tree level) self-interactions ( λφ 4 ) in

How many particles do make a fluid? Qualifying collective behavior in expanding ultracold gases

Collective phenomena in quantum many-body systems are often described in terms of hydrodynamics, an appropriate framework when the involved particle numbers are effectively macroscopic. We propose to

Colloquium: Hydrodynamics and holography of charge density wave phases

In this Colloquium , we review recent progress in the effective description of strongly- correlated phases of matter with spontaneously broken translations, such as charge density waves or Wigner

Collective modes of gluons in an anisotropic thermo-magnetic medium

We study the collective modes of gluon in an anisotropic thermal medium in presence of a constant background magnetic field using the hard-thermal loop (HTL) perturbation theory. The momentum space

Realising a one-dimensional topological gauge theory in an optically dressed Bose-Einstein condensate

Topological gauge theories describe the low-energy properties of certain strongly correlated quantum systems through effective weakly interacting models [1, 2]. A prime example is the Chern-Simons

Quantum simulation of nonequilibrium dynamics and thermalization in the Schwinger model

We present simulations of non-equilibrium dynamics of quantum field theories on digital quantum computers. As a representative example, we consider the Schwinger model, a 1+1 dimensional U(1) gauge

Heavy quarks in turbulent QCD plasmas

Abstract.The quark-gluon plasma, which is produced at an early stage of ultrarelativistic heavy-ion collisions, is expected to be initially strongly populated with chromodynamic fields. We address

Heavy ion collisions quickly form a droplet of quark–gluon plasma (QGP) with a remarkably small viscosity. We give an accessible introduction to how to study this smallest and hottest droplet of

Polarization and Vorticity in the Quark–Gluon Plasma

The quark–gluon plasma (QGP) produced by collisions between ultrarelativistic heavy nuclei is well described in the language of hydrodynamics. Noncentral collisions are characterized by very large

Universal prethermal dynamics of Bose gases quenched to unitarity

TLDR
Degenerate and thermal Bose gases, quenched so that the interparticle interactions are as strong as allowed by quantum mechanics, exhibit dynamics that can be expressed in terms of universal functions.

Decoding the phase structure of QCD via particle production at high energy

TLDR
By analysing particle production in high-energy nuclear collisions, the phase boundary of strongly interacting matter is located and the phase structure of quantum chromodynamics is elucidated, implying quark–hadron duality.

We present an introductory review of the early-time dynamics of high-energy heavy-ion collisions and the kinetics of high-temperature quantum chromodynamic matter. The equilibration mechanisms in the
