Fermion and gluon spectral functions far from equilibrium

نویسندگان

چکیده

Motivated by the quark-gluon plasma, we develop a simulation method to obtain spectral function of (Wilson) fermions non-perturbatively in non-Abelian gauge theory with large gluon occupation numbers [arXiv:2106.11319]. We apply our plasma close its non-thermal fixed point, i.e., far-from-equilibrium self-similar regime, and find mostly very good agreement perturbative hard loop (HTL) calculations. For first time, extract full momentum dependence damping rate fermionic collective excitations compare results recent non-perturbative extractions gluonic functions two three spatial dimensions [arXiv:2101.02715, arXiv:1804.01966].

Far-from-equilibrium computation

We study the possibility of developing far-from-equilibrium computational systems, in analogy with corresponding self-organizing physical systems. We review the computational models developed in analogy with physical systems converging towards equilibrium and the research related to the self-organization of far-from-equilibrium physical systems. Based on this review, we define several nonequili...

Isotropization far from equilibrium

Isotropization occurs on time scales much shorter than the thermal equilibration time. This is a crucial ingredient for the understanding of collision experiments of heavy nuclei or other nonequilibrium phenomena in complex many body systems. We discuss in detail the limitations of estimates based on standard “linear” or relaxationtime approximations, where isotropization and thermal equilibrat...

Ultracold gases far from equilibrium

Ultracold atomic quantum gases belong to the most exciting challenges of modern physics. Their theoretical description has drawn much from (semi-) classical field equations. These mean-field approximations are in general reliable for dilute gases in which the atoms collide only rarely with each other, and for situations where the gas is not too far from thermal equilibrium. With present-day tec...

Anomalous nucleation far from equilibrium.

We present precision Monte Carlo data and analytic arguments for an asymmetric exclusion process, involving two species of particles driven in opposite directions on a 2xL lattice. To resolve a stark discrepancy between earlier simulation data and an analytic conjecture, we argue that the presence of a single macroscopic cluster is an intermediate stage of a complex nucleation process: in small...

Tuning universality far from equilibrium

Possible universal dynamics of a many-body system far from thermal equilibrium are explored. A focus is set on meta-stable non-thermal states exhibiting critical properties such as self-similarity and independence of the details of how the respective state has been reached. It is proposed that universal dynamics far from equilibrium can be tuned to exhibit a dynamical transition where these cri...
