Even-denominator fractional quantum Hall states in the zeroth Landau level of ABA trilayer graphene
Tanima Chanda, Simrandeep Kaur, Harsimran Singh +6
The paper reports the observation of robust even‑denominator fractional quantum Hall states in the zeroth Landau level of ABA trilayer graphene, linking their stability to inversio…
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…
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 f…
Tunable Band Inversion in Trilayer Graphene
Harsimran Kaur Mann, Simrandeep Kaur, Safil Mullick +4
Displacement field control of elecronic bands in low-dimensional systems is a promising route toward engineering emergent quantum phases. Here, we report displacement-field-induced…
Controlling particle-hole symmetry of fractional quantum hall states in trilayer graphene
