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…
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…
Signatures of moiré intralayer biexcitons and exciton-phason coupling in WSe2/WS2 heterostructures
Ranju Dalal, Harsimran Singh, Rwik Dutta +6
Interactions among electronic and lattice degrees-of-freedom are foundational to various phases in condensed-matter physics, yet the dynamic interplay between excitonic and phononi…
Controlling particle-hole symmetry of fractional quantum hall states in trilayer graphene
Simrandeep Kaur, Harsimran Singh, Kenji Watanabe +5
We present a detailed experimental study of the particle-hole symmetry (PHS) of the fractional quantum Hall (FQH) states about half filling in a multiband system. Specifically, we…
