Mixed Floquet Lattice model for gapless topology
Goutham Vinjamuri, Ashutosh Dubey, Ankur Das
We investigate the realization of a time-reversal-broken Weyl semimetal in Floquet synthetic dimensions generated by two incommensurate drives, in the spirit of topological frequen…
Shot noise signatures of candidate states for the fractional quantum Hall state
Goutham Vinjamuri, Ankur Das
Fractional quantum Hall (FQH) states are highly sought after because of their ability to host non-abelian anyons, whose braiding statistics make them excellent candidates for qubit…
Half-integer thermal conductance in the absence of Majorana mode
Ujjal Roy, Sourav Manna, Souvik Chakraborty +6
Considering a range of candidate quantum phases of matter, half-integer thermal conductance () is believed to be an unambiguous evidence of non-Abelian states. It h…
Fractional Quantum Hall phases of graphene beyond ultra-short range intervalley-anisotropic interaction
Oleg Grigorev, Ankur Das
Recent experimental and theoretical development in the Quantum Hall effect in monolayer graphene showed that the previous model of the valley-anisotropy interaction is incomplete,…
Half-quantized Hall Plateaus in the Confined Geometry of Graphene
Preeti Pandey, Sourav Manna, Kristiana N. Frei +8
Since the ground-breaking discovery of the quantum Hall effect, half-quantized quantum Hall plateaus have been some of the most studied and sought-after states. Their importance st…
