Universal magnetotunnel conductance at a Weyl semimetal-layered Chern insulator junction
Nirnoy Basak, Sumathi Rao, Faruk Abdulla
We investigate electronic transport across a junction between a Weyl semimetal (WSM) and a layered Chern insulator (LCI) in the presence of a magnetic field perpendicular to the in…
Magneto tunnel conductance across twisted Weyl semimetal junctions
Nirnoy Basak, Sumathi Rao, Faruk Abdulla
We investigate magnetotransport across an interface between two Weyl semimetals (finite in both directions) whose Weyl nodes project onto two different surfaces which are twisted w…
Can Majorana zero modes in quantum Hall edges survive edge reconstruction?
Kishore Iyer, Amulya Ratnakar, Sumathi Rao +1
Parafermion zero modes can be trapped in the domain walls of quantum Hall edges proximitized by superconductors and ferromagnets. The fractional quantum Hall side strip ar…
Quantum spin Hall insulator in proximity with a superconductor: Transition to the Fulde-Ferrell-Larkin-Ovchinnikov state driven by a Zeeman field
Suman Jyoti De, Udit Khanna, Sumathi Rao +1
We investigate the effects of introducing a boost (a Zeeman field parallel to the spin quantization axis) at the proximitized helical edge of a two-dimensional (2D) quantum spin Ha…
Two-channel Kondo problem in coupled interacting helical liquids
Sourav Biswas, Alessandro De Martino, Sumathi Rao +1
We study the two-channel Kondo problem in the context of two interacting helical liquids coupled to a spin- magnetic impurity. We show that the interactions between the tw…
Global phase diagram of charge neutral graphene in the quantum Hall regime for generic interactions
Suman Jyoti De, Ankur Das, Sumathi Rao +2
Monolayer graphene at charge neutrality in a quantizing magnetic field is a quantum Hall ferromagnet. Due to the spin and valley (near) degeneracies, there is a plethora of possibl…
