Symmetry Protected Bulk-Boundary Correspondence in Interacting Topological Insulators
Kiran Babasaheb Estake, Dibyendu Roy
We establish a quantitative bulk-boundary correspondence in interacting topological insulators by relating many-body topological invariants to characteristic degeneracy structures…

Anomalous dynamical response of non-Hermitian topological phases
Ritu Nehra, Dibyendu Roy
Composite topological phases with intriguing topology like Mbius strips emerge in sublattice symmetric non-Hermitian systems due to spontaneous breaking of time-reversal symme…
