Spontaneous Symmetry Breaking and Frustrated Phases
Heitor Casasola, Carlos A. Hernaski, Pedro R. S. Gomes +1
We study a system involving a single quantum degree of freedom per site of the lattice interacting with a few neighbors (up to second neighbors), with the interactions chosen as to…

Supersymmetric Quantum Spherical Spins with Short-Range Interactions
L. V. T. Tavares, L. G. dos Santos, G. T. Landi +2
This work is dedicated to the study of a supersymmetric quantum spherical spin system with short-range interactions. We examine the critical properties both a zero and finite tempe…

Supersymmetric Quantum Spherical Spins
L. G. dos Santos, L. V. T. Tavares, P. F. Bienzobaz +1
In this work we investigate properties of a supersymmetric extension of the quantum spherical model from an off-shell formulation directly in the superspace. This is convenient to…
