“…Quark-star models [117] appear as soon as quarks are proposed; "after" gluons join quarks [118], within a year -Peter Carruthers in 1973/74 [119] recognized that dense quark matter would be a quite "bizarre" plasma and he explores its many body aspects. His paper has priority but is also hard to obtain, published in a new journal that did not last.…”

Abstract. In the context of the Hagedorn temperature half-centenary I describe our understanding of the hot phases of hadronic matter both below and above the Hagedorn temperature. The first part of the review addresses many frequently posed questions about properties of hadronic matter in different phases, phase transition and the exploration of quark-gluon plasma (QGP). The historical context of the discovery of QGP is shown and the role of strangeness and strange antibaryon signature of QGP illustrated. In the second part I discuss the corresponding theoretical ideas and show how experimental results can be used to describe the properties of QGP at hadronization. The material of this review is complemented by two early and unpublished reports containing the prediction of the different forms of hadron matter, and of the formation of QGP in relativistic heavy ion collisions, including the discussion of strangeness, and in particular strange antibaryon signature of QGP.

“…Non-Abelian gauge theories [7,8], on the other hand, are confining and give rise to massive particles. For example, in Quantum Chromodynamics (QCD) [9][10][11] with the non-Abelian gauge group SU (3), massless gluons and almost massless quarks are turned into massive hadrons, including protons and neutrons. However, thanks to the property of asymptotic freedom, the hadron masses are exponentially small compared to the ultimate cut-off scale (e.g.…”

Ultracold quantum gases and lattice systems: quantum simulation of lattice gauge theories

Abelian and non-Abelian gauge theories are of central importance in many areas of physics. In condensed matter physics, Abelian U(1) lattice gauge theories arise in the description of certain quantum spin liquids. In quantum information theory, Kitaev's toric code is a Z(2) lattice gauge theory. In particle physics, Quantum Chromodynamics (QCD), the non-Abelian SU(3) gauge theory of the strong interactions between quarks and gluons, is nonperturbatively regularized on a lattice. Quantum link models extend the concept of lattice gauge theories beyond the Wilson formulation, and are well suited for both digital and analog quantum simulation using ultracold atomic gases in optical lattices. Since quantum simulators do not suffer from the notorious sign problem, they open the door to studies of the real-time evolution of strongly coupled quantum systems, which are impossible with classical simulation methods. A plethora of interesting lattice gauge theories suggests itself for quantum simulation, which should allow us to address very challenging problems, ranging from confinement and deconfinement, or chiral symmetry breaking and its restoration at finite baryon density, to color superconductivity and the real-time evolution of heavy-ion collisions, first in simpler model gauge theories and ultimately in QCD.

“…The three-gluon vertex is the basic object responsible for the non-Abelian nature of Quantum Chromodynamics [1]. Perturbative corrections to gluonic vertices are very important in real physical calculations, such as multijet production at the hadron colliders (see e.g.…”
