Topological signatures in the quench dynamics of periodically driven quantum systems
Ashutosh Dubey, Hironmoy Pratihar, Diptiman Sen +1
We study the quench dynamics of graphene, without and with a staggered mass, following the sudden switch-on of circularly polarized light where coupling to a fermionic bath is also…
New frontiers in quantum science and technology using van der Waals Josephson junctions
Joydip Sarkar, Ayshi Mukherjee, Amit Basu +3
Over the last decade, the development of Josephson devices based on van der Waals (vdW) materials has advanced rapidly, representing a paradigm shift driven by the advent of 2D mat…
Emergent topological phase from a one-dimensional network of defects
Rahul Singh, Ritajit Kundu, Arijit Kundu +1
Symmetry-protected topological phases of matter, characterized by non-trivial band topology, are spectrally gapped and show non-trivial boundary phenomena. Here, we show that scatt…
Umklapp-Enhanced Interlayer Valley Drag in Moiré Bilayers
Ritajit Kundu, Mandar M. Deshmukh, Herbert A. Fertig +1
Van der Waals materials may be combined to form moiré patterns that are effectively crystal lattices. These systems are unique in that their in-plane unit cell sizes may be orders…
Quantum interference in a twisted high-Tc SQUID senses emergent interfacial order
Amit Basu, Samrat Ash, Ritajit Kundu +12
Engineering artificial systems by twisting and stacking van der Waals materials has proven to be an excellent platform for exploring emergent quantum phenomena that can be signific…
