Sum rules and density-wave modes in spin-singlet fractional quantum Hall fluids
Ritajit Kundu, Rakesh K. Dora, Dung Xuan Nguyen +1
Fractional quantum Hall (FQH) states are prototypical examples of strongly interacting topologically ordered systems. In this work, we obtain thermodynamic fits on the plane for th…
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…
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…
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…
Josephson junction of minimally twisted bilayer graphene
Ritajit Kundu, Arijit Kundu
We theoretically investigate the transport properties of Josephson junctions composed of superconductor/minimally twisted bilayer graphene/superconductor structures. In the presenc…
Broken symmetry and competing orders in Weyl semimetal interfaces
Ritajit Kundu, H. A. Fertig, Arijit Kundu
We consider interaction-induced broken symmetry states of two Weyl semimetal surfaces with multiple Fermi-arc (FA) states. In the presence of inter- and intra-surface Coulomb inter…
Schwinger-Boson mean-field study of spin-1/2 -- model in honeycomb lattice: thermal Hall signature
Rohit Mukherjee, Ritajit Kundu, Avinash Singh +1
We theoretically investigate, within the Schwinger-Boson mean-field theory, the transition from a gapped quantum spin-liquid, in a - Heisenberg spin-1/2 system in…
Role of orbital off-diagonal spin and charge condensates in a three orbital model for -- Coulomb renormalized spin-orbit coupling, orbital moment, and tunable magnetic order
Shubhajyoti Mohapatra, Ritajit Kundu, Ashutosh Dubey +2
Strongly anisotropic spin-orbit coupling (SOC) renormalization and strongly enhanced orbital magnetic moments are obtained in the fully self consistent approach including the orbit…
