Dislocation Non-Hermitian Skin Effect
Frank Schindler, Abhinav Prem
We demonstrate that crystal defects can act as a probe of intrinsic non-Hermitian topology. In particular, in point-gapped systems with periodic boundary conditions, a pair of disl…
Topological Defect Networks for Fractons of all Types
David Aasen, Daniel Bulmash, Abhinav Prem +2
Fracton phases exhibit striking behavior which appears to render them beyond the standard topological quantum field theory (TQFT) paradigm for classifying gapped quantum matter. He…
Lieb-Schultz-Mattis type constraints on Fractonic Matter
Huan He, Yizhi You, Abhinav Prem
The Lieb-Schultz-Mattis (LSM) theorem and its descendants impose strong constraints on the low-energy behavior of interacting quantum systems. In this paper, we formulate LSM-type…
Topological states on fractal lattices
Shriya Pai, Abhinav Prem
We investigate the fate of topological states on fractal lattices. Focusing on a spinless chiral p-wave paired superconductor, we find that this model supports two qualitatively di…
Gauging permutation symmetries as a route to non-Abelian fractons
Abhinav Prem, Dominic J. Williamson
We discuss the procedure for gauging on-site global symmetries of three-dimensional lattice Hamiltonians that permute quasi-particles and provide general arguments d…
Entanglement Spectra of Stabilizer Codes: A Window into Gapped Quantum Phases of Matter
Albert T. Schmitz, Sheng-Jie Huang, Abhinav Prem
The entanglement spectrum (ES) provides a barometer of quantum entanglement and encodes physical information beyond that contained in the entanglement entropy. In this paper, we ex…
