Engineering Quantum Criticality in the Integer Quantum Hall Regime through a Screening Layer
C. T. Tai, P. T. Madathil, A. Gupta +3
Disorder-induced localization of electrons and electron-electron interaction are among the most fundamental problems in condensed matter physics. In two-dimensional electron system…
Spin-Valley Locking in 2H-TaS2 and Its Co-Intercalated Counterpart: Roles of Surface Domains and Co Intercalation
Hai-Lan Luo, Josue Rodriguez, Maximilian Huber +10
Tuning and probing spin-valley coupling is key to understanding correlated ground states in 2-TaS. Its magnetically intercalated analogue, CoTaS, introduces…
Developing fractional quantum Hall states at even-denominator fillings 1/6 and 1/8
Chengyu Wang, P. T. Madathil, S. K. Singh +5
In the extreme quantum limit, when the Landau level filling factor , the dominant electron-electron interaction in low-disorder two-dimensional electron systems leads to exot…
Developing fractional quantum Hall states at = and in the presence of significant Landau level mixing
Siddharth Kumar Singh, A. Gupta, P. T. Madathil +4
Termination of the fractional quantum Hall states (FQHSs) and the emergence of Wigner crystal phases at very small Landau level filling factors () have been of continued intere…
