Meson condensation

M Mannarelli - Particles, 2019 - mdpi.com
We give a pedagogical review of the properties of the various meson condensation phases
triggered by a large isospin or strangeness imbalance. We argue that these phases are …

Interacting Weyl fermions: Phases, phase transitions, and global phase diagram

B Roy, P Goswami, V Juričić - Physical Review B, 2017 - APS
We study the effects of short-range interactions on a generalized three-dimensional Weyl
semimetal, where the band touching points act as the (anti) monopoles of Abelian Berry …

Velocity of sound beyond the high-density relativistic limit from lattice simulation of dense two-color QCD

K Iida, E Itou - Progress of Theoretical and Experimental Physics, 2022 - academic.oup.com
We obtain the equation of state (EoS) for two-color quantum chromodynamics (QCD) at low
temperature and high density from the lattice Monte Carlo simulation. We find that the …

Peaks of sound velocity in two color dense QCD: Quark saturation effects and semishort range correlations

T Kojo, D Suenaga - Physical Review D, 2022 - APS
We discuss stiffening of dense matter in two color QCD (QC 2 D) where hadrons are mesons
and diquark baryons. We study two models which describe a transition of matter from the …

Phase diagram of dense two-color QCD at low temperatures

VV Braguta - Symmetry, 2023 - mdpi.com
This review is devoted to the modern understanding of the two-color QCD phase diagram at
finite baryon density and low temperatures. First, we consider the theoretical picture of this …

Remarks on nuclear matter: How an condensate can spike the speed of sound, and a model of baryons

RD Pisarski - Physical Review D, 2021 - APS
I make two comments about nuclear matter. First, I consider the effects of a coupling
between the O (4) chiral field, ϕ→, and the ω μ meson,∼+ ϕ→ 2 ω μ 2; for any net baryon …

Two-colour QCD phases and the topology at low temperature and high density

K Iida, E Itou, TG Lee - Journal of High Energy Physics, 2020 - Springer
A bstract We delineate equilibrium phase structure and topological charge distribution of
dense two-colour QCD at low temperature by using a lattice simulation with two-flavour …

Dense two-color QCD towards continuum and chiral limits

T Boz, P Giudice, S Hands, JI Skullerud - Physical Review D, 2020 - APS
We study two-color QCD with two flavors of Wilson fermion as a function of quark chemical
potential μ and temperature T, for two different lattice spacings and two different quark …

Interacting nodal-line semimetal: Proximity effect and spontaneous symmetry breaking

B Roy - Physical Review B, 2017 - APS
Effects of short-range electronic interactions in a three-dimensional line-node semimetal that
supports linearly dispersing quasiparticles around an isolated loop in the Brillouin zone are …

Probing the hadron mass spectrum in dense two-color QCD with the linear sigma model

D Suenaga, K Murakami, E Itou, K Iida - Physical Review D, 2023 - APS
We investigate modifications of hadron masses at finite quark chemical potential in two-
flavor and two-color QCD, data of which are available from lattice simulations, within a linear …
