Inhomogeneous superconductivity arises when the species participating in pairing phenomenon have different Fermi surfaces with a large enough separation. In these conditions it could be more favorable for each of fermions to stay close its surface and, unlike usual BCS state, Cooper pair nonzero total momentum. For this reason, state gap varies space, ground is inhomogeneous, and crystalline structure might formed. This situation was considered first time by Fulde Ferrell (1964) Larkin...
The TESLA Technical Design Report Part III: Physics at an e+e- Linear Collider
Inhomogeneous superconductors and inhomogeneous superfluids appear in a variety of contexts including quark matter at extreme densities, fermionic systems cold atoms, type-II cuprates, organic superconductors. In the present review focus is on properties high baryonic density, which may exist interior compact stars. The conditions realized these stellar objects tend to disfavor standard symmetric BCS pairing favor an color superconducting phase. are discussed detail particular crystalline...
We study the diagram for chiral phases of QCD on plane temperature and chemical potential. The calculation is based extension a composite-operator formalism already employed zero density. find that, moving along critical line increasing potential, one encounters point separating second-order first-order phase transitions. overall found to qualitatively reproduce pattern Gross-Neveu model. Our suggests occurrence metastable phases.
We study the phases of a two-flavor Nambu--Jona-Lasinio model at finite temperature T, and baryon isospin chemical potentials ${\ensuremath{\mu}}_{B}=({\ensuremath{\mu}}_{u}+{\ensuremath{\mu}}_{d})/2,$ ${\ensuremath{\mu}}_{I}=({\ensuremath{\mu}}_{u}\ensuremath{-}{\ensuremath{\mu}}_{d})/2.$ This completes previous analysis where only small ${\ensuremath{\mu}}_{I}$ were considered.
Chiral transitions in QCD at finite temperature and density are discussed within a composite operator formalism. For massless quarks the phase diagram chemical potentials presents tricritical point intersection of critical line for first-order second-order transitions. The overall picture is not sensibly affected by small quark masses, except that condensate no longer vanishes large temperatures and/or potentials, it remains discontinuous only mass values. Such effects...
We calculate the Meissner masses of gluons in neutral three-flavor color superconducting matter for finite strange quark mass. In CFL phase are slowly varying function For large mass, so-called gCFL phase, with colors a=1,2 become imaginary, indicating an instability.
Using an effective-potential approach for composite operators, we study dynamical symmetry breaking in QCD-like theories with massless quarks. The analysis is extended to massive quarks QCD three flavors and the masses of pseudoscalar-octet mesons their decay constants are calculated. Renormalization-group corrections taken into account. effective potential depends on standard parameters QCD: ${\ensuremath{\Lambda}}_{\mathrm{QCD}}$, ${m}_{u}$, ${m}_{d}$, ${m}_{s}$ a mass scale...
We introduce a general method to construct, directly in configuration space, classes of dynamical systems invariant under generalizations the Carroll and Galilei groups. The does not make use any nonrelativistic limiting procedure, although starting point is Lagrangian Poincar\'e full space. It consists considering spacetime $D+1$ dimensions partitioning it two parts, first Minkowskian second Euclidean. action terms that are separately Euclidean partitioning. One those contains system...
In this paper we analyze two different models of interacting conformal Carroll particles that can be obtained as the Carrollian limit relativistic particles. The first model describes with zero velocity and exhibits infinite dimensional symmetries which are reminiscent BMS symmetries. A second interaction is proposed, where have nonzero therefore, a consequence $c\ensuremath{\rightarrow}0$, tachyons. Infinite present also in model.
