Screening-controlled dynamical criticality in the quantum Hall regime
Tanima Chanda, Simrandeep Kaur, Anantbir Virk +5
At continuous electronic phase transitions, Coulomb interactions can modify the relation between length, energy, and temperature, but experimentally disentangling their effects on…
Diagnosing the origin of quantum oscillation beating in graphene
Akash Adhikary, Sunit Das, Divya Sahani +2
Magnetic quantum oscillations are usually periodic in inverse magnetic field, and their amplitude can show beating when two nearby frequencies interfere. In graphene-based hexagona…
Layer-Polarization-Driven Metal-Insulator Transition in multi-band Graphene Moire' Superlattices
Harsimran Kaur Mann, Simrandeep Kaur, Harsimran Singh +7
Graphene/hBN moiré superlattices provide a highly tunable platform for exploring emergent quantum phases in low-dimensional systems. Here, we investigate the moiré superlattice for…
Quantum Transport Spectroscopy of Pseudomagnetic Field in Graphene
Divya Sahani, Sunit Das, Kenji Watanabe +3
Nonuniform strain in graphene acts as a valley-dependent gauge field, generating pseudomagnetic fields (PMFs) that mimic real magnetic fields but preserve global time-reversal symm…
Coexisting Massive and Massless Dirac Fermions in Moire'-Reconstructed Bilayer Graphene
Mohit Kumar Jat, Kenji Watanabe, Takashi Taniguchi +1
We report the emergence of massless Dirac fermions in moiré-reconstructed bands of bilayer graphene (BLG) aligned with hexagonal boron nitride (hBN). Magnetotransport measurements…
Odd-parity longitudinal magnetoconductivity in time-reversal symmetry broken materials
Sunit Das, Akash Adhikary, Divya Sahani +2
Magnetotransport measurements are a sensitive probe of symmetry and electronic structure in quantum materials. While conventional metals exhibit longitudinal magnetoconductivity th…
