Fractal Subsystem Symmetries, Anomalies, Boundaries, and Effective Field Theory
Heitor Casasola, Guilherme Delfino, Yizhi You +2
This work reports an extensive study of three-dimensional topological ordered phases that, in one of the directions behave like usual topological order concerning mobility of excit…
Fractal Subsystem Symmetries, 't Hooft Anomalies, and UV/IR Mixing
Heitor Casasola, Guilherme Delfino, Pedro R. S. Gomes +1
In this work, we study unconventional anisotropic topologically ordered phases in that manifest type-II fractonic physics along submanifolds. While they behave as usual topolo…
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…
Modulated phases in a three-dimensional Maier-Saupe model with competing interactions
P. F. Bienzobaz, Na Xu, Anders W. Sandvik
This work is dedicated to the study of the discrete version of the Maier-Saupe model in the presence of competing interactions. The competition between interactions favoring differ…
Quantum Spherical Spins with Local Symmetry
Pedro R. S. Gomes, P. F. Bienzobaz
We construct a quantum system of spherical spins with a continuous local symmetry. The model is exactly soluble in the thermodynamic limit and exhibits a number of interesting prop…
Competing interactions and the Lifshitz-type Nonlinear Sigma Model
Pedro R. S. Gomes, P. F. Bienzobaz, M. Gomes
We establish the equivalence between the continuum limit of the quantum spherical model with competing interactions, which is relevant to the investigation of Lifshitz points, and…
Stochastic Quantization of the Spherical Model and Supersymmetry
P. F. Bienzobaz, Pedro R. S. Gomes, M. Gomes
We use the stochastic quantization method to construct a supersymmetric version of the quantum spherical model. This is based on the equivalence between the Brownian motion describ…
Supersymmetric Extension of the Quantum Spherical Model
Pedro R. S. Gomes, P. F. Bienzobaz, M. Gomes
In this work, we present a supersymmetric extension of the quantum spherical model, both in components and also in the superspace formalisms. We find the solution for short/long ra…
Quantum spherical model with competing interactions
P. F. Bienzobaz, S. R. Salinas
We analyze the phase diagram of a quantum mean spherical model in terms of the temperature , a quantum parameter , and the ratio , where refers to f…
