Supersolid crystals of dipolar excitons in a lattice
C. Morin, C. Lagoin, T. Gupta +5
In condensed-matter physics, long-range correlations introduce quantum states of matter that challenge intuition. For instance, supersolids combine symmetry-breaking crystalline st…
High-order two-component fractional quantum Hall states around filling factor
E. Bell, K. W. Baldwin, L. N. Pfeiffer +2
Two-component fractional quantum Hall (2C-FQH) states in electron bilayers have been known for decades, yet their experimental realization remained limited to low-order fractions.…
Competing Many-Body Phases at Small Fillings in Ultrahigh-Quality GaAs 2D Hole Systems: Role of Landau Level Mixing
Chengyu Wang, A. Gupta, S. K. Singh +4
The fractional quantum Hall state (FQHS), an incompressible liquid state hosting anyonic excitations with fractional charge and statistics, represents a compelling many-body phase…
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…
