Probing the hadron mass spectrum in dense two-color QCD with the linear sigma model
Daiki Suenaga, Kotaro Murakami, Etsuko Itou +1
We investigate modifications of hadron masses at finite quark chemical potential in two-flavor and two-color QCD, of which the data are available from lattice simulations, within a…
Velocity of Sound beyond the High-Density Relativistic Limit from Lattice Simulation of Dense Two-Color QCD
Kei Iida, Etsuko Itou
We obtain the equation of state (EoS) for two-color QCD at low temperature and high density from the lattice Monte Carlo simulation. We find that the velocity of sound exceeds the…
Larkin-Ovchinnikov-Fulde-Ferrell state in two-color quark matter
Kenji Fukushima, Kei Iida
We explore the phase structure of two-color and two-flavor QCD in the space of the quark chemical potential μ_q and the isospin chemical potential μ_I. Using a mean-field model we…
Instability of a gapless color superconductor with respect to inhomogeneous fluctuations
Kei Iida, Kenji Fukushima
We systematically apply density functional theory to determine the kind of inhomogeneities that spontaneously develop in a homogeneous gapless phase of neutral two-flavor superflui…
Feedback effects on the pairing interaction in color superconductors near the transition temperature
Kei Iida
We examine the role that the gap dependence of the pairing interaction plays in the gap equation for a weakly coupled uniform superfluid of three-flavor massless quarks near the tr…
Magnetic vortex in color-flavor locked quark matter
Kei Iida
Within Ginzburg-Landau theory, we study the structure of a magnetic vortex in color-flavor locked quark matter. This vortex is characterized by winding of the SU(3) phase in color-…
Thermal fluctuations of gauge fields and first order phase transitions in color superconductivity
Taeko Matsuura, Kei Iida, Tetsuo Hatsuda +1
We study the effects of thermal fluctuations of gluons and the diquark pairing field on the superconducting-to-normal state phase transition in a three-flavor color superconductor,…
Superfluid phases of quark matter. III. Supercurrents and vortices
Kei Iida, Gordon Baym
We study, within Ginzburg-Landau theory, the responses of three-flavor superfluid quark-gluon plasmas to external magnetic fields and rotation, in both the color-flavor locked and…
Superfluid phases of quark matter, II: Phenomenology and sum rules
Kei Iida, Gordon Baym
We derive sum rules for a uniform, isotropic superfluid quark-gluon plasma with massless quarks, first laying out the phenomenological equations obeyed by a color superconductor in…
The superfluid phases of quark matter: Ginzburg-Landau theory and color neutrality
Kei Iida, Gordon Baym
We apply Ginzburg-Landau theory to determine BCS pairing in a strongly-coupled uniform superfluid of three-flavor massless quarks in flavor equilibrium. We elucidate the phase diag…
