Relations between density-density correlators of states in the maximal spin multiplet
Ritajit Kundu, Ajit C. Balram
We present identities relating the pair-correlation functions and static structure factors of states in the maximal spin multiplet. This allows us to compute these density-density…
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…
Topologically switchable transport in a bundled cable of wires
Nirnoy Basak, Ritajit Kundu, Basudeb Mondal +1
Advances in the next generation of mesoscopic electronics require an understanding of topological phases in inhomogeneous media and the principles that govern them. Motivated by th…
