Does shot noise always provide the quasiparticle charge?
Sourav Biswas, Rajarshi Bhattacharyya, Hemanta Kumar Kundu +5
The fractional charge of quasiparticles is a fundamental feature of quantum Hall effect (QHE) States. The charge has long been measured via shot-noise at moderate temperatures (…
Coexistence of Canted Antiferromagnetism and Bond-order in Graphene
Ankur Das, Ribhu K. Kaul, Ganpathy Murthy
Motivated by experimental studies of graphene in the quantum Hall regime, we revisit the phase diagram of a single sheet of graphene at charge neutrality. Because of spin and valle…
Time-reversal-broken Weyl semimetal in the Hofstadter regime
Faruk Abdulla, Ankur Das, Sumathi Rao +1
We study the phase diagram for a lattice model of a time-reversal-broken three-dimensional Weyl semimetal (WSM) in an orbital magnetic field with a flux of per unit cell…
Layer Coherent Phase in Double Layer graphene at
Amartya Saha, Ankur Das
In the recent advancement in graphene heterostructures, it is possible to create a double layer tunnel decoupled graphene system that has a strong interlayer electronic interaction…
Dc Electrical Current Generated by Upstream Neutral Modes
Ankur Das, Sumathi Rao, Yuval Gefen +1
Quantum Hall phases are gapped in the bulk but support chiral edge modes, both charged and neutral. Here we consider a circuit where the path from the source of electric current to…
