Quantum oscillation spectroscopy of Fermi-surface topologies in tetralayer graphene
Abhijit Halder, Harsh Varshney, Snehamoyee Hazra +7
Quantum oscillations offer a direct probe of Fermi-surface topology and electronic degeneracy, yet disentangling both simultaneously across the Lifshitz transitions of multiband sy…
Van Hove singularity-driven giant Nernst signal in twisted double bilayer graphene
Ujjal Roy, Monosij Roy, Unmesh Ghorai +8
Twisted graphene layers host van Hove singularities (vHSs), peaks in the electronic density of states, thought to drive exotic phases in moiré materials, but their effect on therma…
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 ha…
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…
