The Dirac spectrum and the BEC-BCS crossover in QCD at nonzero isospin asymmetry

BB Brandt, F Cuteri, G Endrődi, S Schmalzbauer - Particles, 2020 - mdpi.com
For large isospin asymmetries, perturbation theory predicts the quantum chromodynamic
(QCD) ground state to be a superfluid phase of u and d¯ Cooper pairs. This phase, which is …

Classification of the quantum chaos in colored Sachdev-Ye-Kitaev models

F Sun, Y Yi-Xiang, J Ye, WM Liu - Physical Review D, 2020 - APS
The random matrix theory (RMT) can be used to classify both topological phases of matter
and quantum chaos. We develop a systematic and transformative RMT to classify the …

We study the phase diagram of two-flavor massless two-color QCD (QC 2 D) under the
presence of quark chemical potentials and imaginary isospin chemical potentials. At the …

Chiral symmetry breaking with no bilinear condensate revisited

T Kanazawa - Journal of High Energy Physics, 2015 - Springer
