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…
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…
Superconducting magic-angle twisted trilayer graphene hosts competing magnetic order and moiré inhomogeneities
Ayshi Mukherjee, Surat Layek, Subhajit Sinha +13
The microscopic mechanism of superconductivity in the magic-angle twisted graphene family, including magic-angle twisted trilayer graphene (MATTG), is poorly understood. Properties…
Time-resolved ARPES and optical transport properties of irradiated twisted bilayer graphene in steady-state
Ashutosh Dubey, Ritajit Kundu, Arijit Kundu
We theoretically investigate the trARPES spectrum and optical Hall conductivity in periodically driven twisted bilayer graphene, considering both steady-state and "projected" occup…
