Entanglement Entropy From Tensor Network States for Stabilizer Codes
Huan He, Yunqin Zheng, B. Andrei Bernevig +1
In this paper, we present the construction of tensor network states (TNS) for some of the degenerate ground states of 3D stabilizer codes. We then use the TNS formalism to obtain t…
A simple anisotropic three-dimensional quantum spin liquid with fracton topological order
Olga Petrova, Nicolas Regnault
We present a three-dimensional cubic lattice spin model, anisotropic in the direction, that exhibits fracton topological order. The latter is a novel type of topological…
Exact Excited States of Non-Integrable Models
Sanjay Moudgalya, Stephan Rachel, B. Andrei Bernevig +1
We discuss a method of numerically identifying exact energy eigenstates for a finite system, whose form can then be obtained analytically. We demonstrate our method by identifying…
Numerical investigation of gapped edge states in fractional quantum Hall-superconductor heterostructures
C. Repellin, A. M. Cook, T. Neupert +1
Fractional quantum Hall-superconductor heterostructures may provide a platform towards non-abelian topological modes beyond Majoranas. However their quantitative theoretical study…
Emergent particle-hole symmetry in spinful bosonic quantum Hall systems
Scott D. Geraedts, Cecile Repellin, Chong Wang +3
When a fermionic quantum Hall system is projected into the lowest Landau level, there is an exact particle-hole symmetry between filling fractions and . We investigate whe…
