Wilson loop invariants and bulk-boundary correspondence in higher-order topological insulators with two anticommuting mirror symmetries
Suman Aich, Babak Seradjeh
We investigate the higher-order bulk-boundary correspondence in a family of chiral-symmetric Bloch Hamiltonians with anticommuting mirror symmetries. These models generalize the $π…
Selective bulk-boundary correspondence in higher-order topological insulators with anticommuting mirror and chiral symmetries
Suman Aich, Babak Seradjeh
We investigate higher-order topological insulators protected by chiral and anticommuting mirror symmetries. Using models in the BDI class, which include the prototypical topologica…
Report on reproducibility in condensed matter physics
A. Akrap, D. Bordelon, S. Chatterjee +20
We present recommendations to improve reproducibility and replicability in condensed matter physics. This area of physics has consistently produced both fundamental insights into t…
Multiple tunable real-space degeneracies in graphene irradiated by twisted light
Suman Aich, Babak Seradjeh
We report the theoretical discovery of multiple real-space degenerate Floquet-Bloch states in monolayer graphene coherently driven by twisted circularly-polarized light. Using Floq…
Josephson-Current Signatures of Unpaired Floquet Majorana Bound States
Rekha Kumari, Babak Seradjeh, Arijit Kundu
We theoretically study the transport signatures of unpaired Floquet Majorana bound states in the Josephson current of weakly linked, periodically driven topological superconductors…
Enhancement of High Harmonic Generation in Bulk Floquet Systems
Abhishek Kumar, Yantao Li, Babak Seradjeh
We formulate a theory of bulk optical current for a periodically driven system, which accounts for the mixing of external drive and laser field frequencies and, therefore, the broa…
