Superconductivity in twisted multilayer graphene: A smoking gun in recent condensed matter physics* [PDF]
We review the recent discoveries of exotic phenomena in graphene, especially superconductivity. It has been theoretically suggested for more than one decade that superconductivity may emerge in doped graphene-based materials. For single-layer pristine graphene, there are theoretical predictions that spin-singlet d + id pairing superconductivity is ...

Vortex matter in U ( 1 ) × U ( 1 ) × Z 2 phase-separated superconducting condensates [PDF]
We study the properties of vortex solutions and magnetic response of two-component U(1)×U(1)×Z2 superconductors, with phase separation driven by intercomponent density-density interaction. Such a theory can be viewed arising from the breakdown of SU(2) symmetry by a biquadratic interaction between the components of the field.

Lattice gauge theory for condensed matter physics: ferromagnetic superconductivity as its example [PDF]
Recent theoretical studies of various strongly-correlated systems in condensed matter physics reveal that the lattice gauge theory (LGT) developed in high-energy physics is quite a useful tool to understand physics of these systems. Knowledge of LGT is to become a necessary item even for condensed matter physicists. In the first part of this paper, we

Superconductivity close to the Mott state: From condensed-matter systems to superfluidity in optical lattices [PDF]
Since the discovery of high-temperature superconductivity in 1986 by Bednorz and Mueller, great efforts have been devoted to finding out how and why it works. From the d-wave symmetry of the order parameter, the importance of antiferromagnetic fluctuations, and the presence of a mysterious pseudogap phase close to the Mott state, one can conclude that ...

Abstract In this paper, the question of the influence of color superconductivity on the formation of a phase with condensation of charged pions in dense, chirally asymmetric quark matter is studied. We consider it within the framework of the massless Nambu–Jona-Lasinio (NJL) model with a diquark interaction channel at zero temperature ...

Formation of gapless phases of
Electric and color neutral solutions, and the critical conditions for the formation of gapless color superconductors, are investigated in $K^0$ condensed color-flavor locked quark matter for nonzero strange quark mass. We show that as the strange quark mass increases, gapless modes for up-strange quark pairing occur first, followed by down-strange ...

Chiral and Diquark condensates at large magnetic field in two-flavor superconducting quark matter
We study the effect of a large magnetic field on the chiral and diquark condensates in a regime of moderately dense quark matter. Our focus is on the inter-dependence of the two condensates through non-perturbative quark mass and strong coupling effects, which we address in a 2-flavor Nambu-Jona-Lasinio (NJL) model. For magnetic fields $eB\lesssim 0.01$
