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…
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…
Possible phases of the spin- model on a honeycomb lattice by boson-vortex duality
Han Ma
Motivated by recent numerical work, we use the boson-vortex duality to study the possible phases of the frustrated spin- XXZ models on the honeycomb lattice.…
Fracton topological order via coupled layers
Han Ma, Ethan Lake, Xie Chen +1
In this work, we develop a coupled layer construction of fracton topological orders in spatial dimensions. These topological phases have sub-extensive topological ground-stat…
