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 ...

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

50 Years of quantum chromodynamics [PDF]

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.

Quantum simulation of colour in perturbative quantum chromodynamics [PDF]

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 matrices of SU(3)symmetry on comparing the multiplication tables for Gell-Mann matrices of SU(3)symmetry and octonion basis elements.

Differential Dyson–Schwinger equations for quantum chromodynamics [PDF]

European Physical Journal C: Particles and Fields, 2020
Using a technique devised by Bender, Milton and Savage, we derive the Dyson–Schwinger equations for quantum chromodynamics in differential form. We stop our analysis to the two-point functions.

Simulating one-dimensional quantum chromodynamics on a quantum computer: Real-time evolutions of tetra- and pentaquarks [PDF]

Physical Review Research, 2023
Quantum chromodynamics (QCD)—the theory of quarks and gluons—has been studied for decades, but it is yet to be fully understood. A recent example is the prediction and experimental discovery of tetraquarks, which opened a new research field.

Three dimensional quantum chromodynamics [PDF]

, 1992
The subject of this talk was the review of our study of three ($2+1$) dimensional Quantum Chromodynamics. In our previous works, we showed the existence of a phase where parity is unbroken and the flavor group $U(2n)$ is broken to a subgroup $U(n)\times ...

Random Matrix Theory and Quantum Chromodynamics [PDF]

, 2016
These notes are based on the lectures delivered at the Les Houches Summer School in July 2015. They are addressed at a mixed audience of physicists and mathematicians with some basic working knowledge of random matrix theory. The first part is devoted to
