Entangling Superconductivity and Antiferromagnetism

Superconductivity and Antiferromagnetism

We study the structure of symmetric vortices in a Ginzburg–Landau model based on S. C. Zhang’s SO(5) theory of high temperature superconductivity and antiferromagnetism. We consider both a full Ginzburg–Landau theory (with Ginzburg–Landau scaling parameter κ < ∞) and a κ → ∞ limiting model. In all cases we find that the usual superconducting vortices (with normal phase in the central core regio...

Coexistence of Antiferromagnetism and Triplet Superconductivity

Mott transition, antiferromagnetism, and d-wave superconductivity in two-dimensional organic conductors.

We study the Mott transition, antiferromagnetism, and superconductivity in layered organic conductors using the cellular dynamical mean-field theory for the frustrated Hubbard model. A d-wave superconducting phase appears between an antiferromagnetic insulator and a metal for t'/t=0.3-0.7 or between a nonmagnetic Mott insulator (spin liquid) and a metal for t'/t>or=0.8, in agreement with experi...

Duality picture between antiferromagnetism and d-wave superconductivity in t− J model at two dimensions

We show in this paper an interesting relation between elementary and topological excitations in the antiferromagnetic and d-wave superconducting phases of the t−J model at two dimensions. The topological spin and charge excitations in one phase have the same dynamics as elementary excitations in the other phase, except the appearance of energy gaps. Moreover, the transition from one phase to an...
