Disordered Haldane-Shastry model
Shriya Pai, N. S. Srivatsa, Anne E. B. Nielsen
The Haldane-Shastry model is one of the most studied interacting spin systems. The Yangian symmetry makes it exactly solvable, and the model has semionic excitations. We introduce…
Fractons from confinement in one dimension
Shriya Pai, Michael Pretko
Recent work has shown that two seemingly different physical mechanisms, namely fracton behavior and confinement, can give rise to non-ergodicity in one-dimensional quantum many-bod…
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…
Fracton fusion and statistics
Shriya Pai, Michael Hermele
We introduce and develop a theory of fusion and statistical processes of gapped excitations in Abelian fracton phases. The key idea is to incorporate lattice translation symmetry v…
Dynamical scar states in driven fracton systems
Shriya Pai, Michael Pretko
One-dimensional fracton systems can exhibit perfect localization, failing to reach thermal equilibrium under arbitrary local unitary time evolution. We investigate how this nonergo…
