1 8 M ar 2 00 3 Topological Gauge Structure and Phase Diagram of a Doped Antiferromagnet
نویسنده
چکیده
We show that a topological gauge structure in an effective description of the t-J model gives rise to a global phase diagram of antiferromagnetic (AF) and superconducting (SC) phases in a weakly doped regime. Dual confinement and deconfinement of holons and spinons play essential roles here, with a quantum critical point at a doping concentration xc ≃ 0.043. The complex experimental phase diagram at low doping is well described within such a framework.

We investigate numerically and in the one loop approximation a two dimensional SU(3) gauge model of Wilson lines. We propose this model to be a dimensionally reduced model of high temperature QCD 3. In contrast to perturbative dimensional reduction it has an explicit global Z 3 symmetry in the action, and a confinement-deconfinement transition. The phase diagram of the model also shows a new th...

We discuss the phase structure of a three-dimensional, non-compact Abelian gauge theory (QED3) as a function of the number N of 4-component massless fermions. There is a critical N c up to which there is dynamical fermion mass generation and an associated global symmetry breaking. We review various approaches to the determination of N c , which lead to estimates ranging from N c = 1 to N c = 4....

We numerically investigate the phase diagram of pure U (1) gauge theory with gauge fixing at strong gauge coupling. The FM-FMD phase transition, which proved useful in defining Abelian lattice chiral gauge theory, persists also at strong gauge coupling. However, there the transition seems no longer to be continuous. At large gauge couplings we find evidences for confinement.
متن کاملResonating plaquette phases in SU(4) Heisenberg antiferromagnet
Large spin cold atom systems can exhibit magnetic properties that do not appear in usual spin-1 /2 systems. We investigate the SU 4 resonating plaquette state in the three-dimensional cubic optical lattice with spin-3 /2 cold fermions. A gauge field formalism is constructed to describe the Rokhsar–Kivelson type of Hamiltonian and a duality transformation is used to study the phase diagram. Due ...
