Superfluid stiffness of twisted multilayer graphene: Part-1

ORAL

Abstract

Superfluid stiffness measurements offer a powerful probe of the superconducting state and a primary means to characterize their pairing symmetries. While penetration depth experiments can be used in bulk materials to extract superfluid stiffness, for two-dimensional materials with a small sample volume, alternative methods are required. Here we discuss the development of a technique to measure the superconducting kinetic inductance in low-dimensional materials and apply it to twisted multilayer graphene. We investigate superfluid stiffness as a function of carrier density and temperature and provide interpretations for possible pairing symmetries.
