Entanglement entropy in lattice models with quantum metric
Alexander Kruchkov, Shinsei Ryu
We revisit the connection between entanglement entropy and quantum metric in topological lattice systems, and provide an elegant and concise proof of this connection. In gapped two…

Magneto-Thermoelectric Transport in Graphene Quantum Dot with Strong Correlations
Laurel E. Anderson, Antti Laitinen, Andrew Zimmerman +7
Disorder at the etched edges of graphene quantum dots (GQD) enables random all-to-all interactions between localized charges in partially-filled Landau levels, providing a potentia…

Spectral sum rules reflect topological and quantum-geometric invariants
Alexander Kruchkov, Shinsei Ryu
Topological invariants are fundamental characteristics reflecting global properties of quantum systems, yet their exploration has predominantly been limited to the static (DC) tran…
