An equation-of-state-meter of quantum chromodynamics transition from deep learning [PDF]

Nature Communications, 2018
The large data generated in heavy-ion collision experiments require careful analysis to understand the physics. Here the authors use the deep-learning method to sort equation of states in QCD transition and analyze the simulated data sets mimicking the ...

50 Years of quantum chromodynamics

European Physical Journal C: Particles and Fields, 2023
Quantum Chromodynamics, the theory of quarks and gluons, whose interactions can be described by a local SU(3) gauge symmetry with charges called “color quantum numbers”, is reviewed; the goal of this review is to provide advanced Ph.D.

The phase diagram of quantum chromodynamics in one dimension on a quantum computer [PDF]

Nature Communications
The quantum chromodynamics (QCD) phase diagram, which reveals the state of strongly interacting matter at different temperatures and densities, is key to answering open questions in physics, ranging from the behaviour of particles in neutron stars to the

A Gentle Introduction to Lattice Field Theory [PDF]

Entropy
The principles of Lattice Field Theory (LFT), in particular Lattice Gauge Theory (LGT), are explained for a nonspecialist audience. We describe some of the successes of the program; we also discuss the relationship between LFT and Quantum Cellular ...

Quantum chromodynamics

The European Physical Journal C, 2000
Abstract In QCD loop calculations we often encounter the some SUC(3) group theoretical factors. In this problem you will be asked to calculate such factors for the general case SU(n) rather than the n = 3 special situation of three colours.

Quantum simulation of colour in perturbative quantum chromodynamics

SciPost Physics, 2023
Quantum computers are expected to give major speed-ups for the simulation of quantum systems. In this work, we present quantum gates that simulate the colour part of the interactions of quarks and gluons in perturbative quantum chromodynamics (QCD). As a

Octonion Quantum Chromodynamics [PDF]

International Journal of Theoretical Physics, 2012
Starting with the usual definitions of octonions, an attempt has been made to establish the relations between octonion basis elements and Gell-Mann λmatrices of SU(3)symmetry on comparing the multiplication tables for Gell-Mann λmatrices of SU(3)symmetry and octonion basis elements.

Gravitational wave signatures of phase transition from hadronic to quark matter in isolated neutron stars and binaries [PDF]

EPJ Web of Conferences, 2022
The fundamental constituent of matter at high temperature and density has intrigued physicists for quite some time. Recent results from heavy-ion colliders have enriched the Quantum Chromodynamics phase diagram at high temperatures and low baryon density.
