Probing the pairing symmetry of moiré graphene superconductors
Sayak Biswas, Rajdeep Sensarma, Mohit Randeria
The pairing symmetry of magic-angle moiré graphene is a fundamental question that remains unresolved. Combining experimental and theoretical inputs, we constrain the superconducti…

Measurement-Induced Dynamical Quantum Thermalization
Marvin Lenk, Sayak Biswas, Anna Posazhennikova +1
One of the fundamental problems of quantum statistical physics is how an ideally isolated quantum system can ever reach thermal equilibrium behavior despite the unitary time evolut…

Andreev versus Tunneling Spectroscopy of Unconventional Flat Band Superconductors
Sayak Biswas, Saurav Suman, Mohit Randeria +1
STM experiments in the tunneling and Andreev regimes on graphene-based moire superconductors (SC) show two distinct energy scales whose origin is mysterious. We express the conduct…
