Localization of Extended Quantum Objects
Michael Pretko, Rahul M. Nandkishore
A quantum system of particles can exist in a localized phase, exhibiting ergodicity breaking and maintaining forever a local memory of its initial conditions. We generalize this co…
Recoverable Information and Emergent Conservation Laws in Fracton Stabilizer Codes
A. T. Schmitz, Han Ma, Rahul M. Nandkishore +1
We introduce a new quantity, that we term recoverable information, defined for stabilizer Hamiltonians. For such models, the recoverable information provides a measure of the topol…
Gapless insulating edges of dirty interacting topological insulators
Yang-Zhi Chou, Rahul M. Nandkishore, Leo Radzihovsky
We demonstrate that a combination of disorder and interactions in a two-dimensional bulk topological insulator can generically drive its helical edge insulating. We establish this…
Topological Entanglement Entropy of Fracton Stabilizer Codes
Han Ma, A. T. Schmitz, S. A. Parameswaran +2
Entanglement entropy provides a powerful characterization of two-dimensional gapped topological phases of quantum matter, intimately tied to their description by topological quantu…
Emergent Phases of Fractonic Matter
Abhinav Prem, Michael Pretko, Rahul Nandkishore
Fractons are emergent particles which are immobile in isolation, but which can move together in dipolar pairs or other small clusters. These exotic excitations naturally occur in c…
Interplay of Coulomb interactions and disorder in three dimensional quadratic band crossings without time-reversal symmetry and with unequal masses for conduction and valence bands
Ipsita Mandal, Rahul M. Nandkishore
Coulomb interactions famously drive three dimensional quadratic band crossing semimetals into a non-Fermi liquid phase of matter. In a previous work, Phys. Rev. B 95, 205106 (2017)…
