Abstract: Abstract We compute the entanglement entropy in a 2+1 dimensional topological order in the presence of gapped boundaries. Specifically, we consider entanglement cuts that cut through the boundaries. We argue that based on general considerations… read more here.

Abstract: We report the realization of a semimetal state in a phononic crystal, which hosts nodal-chain degeneracy in momentum space. The nodal-chain dispersion consists of interconnecting degenerate lines, and is protected by the nonsymmorphic and time-reversal… read more here.

DOI: 10.1103/physrevb.101.094307
Abstract: We demonstrate that modulations of the stiffness properties of an elastic plate along a spatial dimension induce edge states spanning non-trivial gaps characterized by integer valued Chern numbers. We also show that topological pumping is… read more here.

DOI: 10.1103/physrevb.107.205416
Abstract: In this study we investigate the effect of random point disorder on the surface states of a topological insulator with out-of-plane magnetization. We consider the disorder within a high order Born approximation. The Born series… read more here.

DOI: 10.1103/physrevlett.126.063601
Abstract: We identify a class of dressed atom-photon states forming at the same energy of the atom at any coupling strength. As a hallmark, their photonic component is an eigenstate of the bare photonic bath with… read more here.
