Absence of heat flow in ν = 0 quantum Hall ferromagnet in bilayer graphene
Ravi Kumar, Saurabh Kumar Srivastav, Ujjal Roy +6
The charge neutrality point of bilayer graphene, denoted as ν = 0 state, manifests competing phases marked by spontaneously broken isospin (spin/valley/layer) symmetries under exte…
Electrical noise spectroscopy of magnons in a quantum Hall ferromagnet
Ravi Kumar, Saurabh Kumar Srivastav, Ujjal Roy +7
Collective spin-wave excitations-magnons-in a quantum Hall ferromagnet are promising quasi-particles for next-generation spintronics devices, including platforms for information tr…
Determination of topological edge quantum numbers of fractional quantum Hall phases
Saurabh Kumar Srivastav, Ravi Kumar, Christian Spånslätt +5
To determine the topological quantum numbers of fractional quantum Hall (FQH) states hosting counter-propagating (CP) downstream () and upstream () edge modes, it is pivo…
