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…
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…
Chiral detection of Majorana bound states at the edge of a quantum spin Hall insulator
Vivekananda Adak, Aabir Mukhopadhyay, Suman Jyoti De +3
A hybrid setup consisting of a superconductivity-proximitized quantum spin Hall (QSH) insulator and a quantum anomalous Hall (QAH) insulator is proposed for chiral injection of ele…
Emergence of spin-active channels at a quantum Hall interface
Amartya Saha, Suman Jyoti De, Sumathi Rao +2
We study the ground state of a system with an interface between and in the quantum Hall regime. Far from the interface, for a range of interaction strengths, the …
Magnetic Flux Periodicity in Second Order Topological Superconductors
Suman Jyoti De, Udit Khanna, Sumathi Rao
The magnetic flux periodicity of is a well known manifestation of Cooper pairing in typical s-wave superconductors. In this paper we theoretically show that the flu…
