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…

Quantized heat flow in moiré chern bands of bilayer graphene
Santanu Samai, Debangan Sarkar, Abhijit Halder +5
When electrons are subjected simultaneously to a magnetic field and a periodic potential, they form the fractal Hofstadter spectrum, whose topological gaps host quantum Hall and Ch…
