Ultra-clean two-dimensional electron systems (2DES) under high perpendicular magnetic field form diverse quantum ground states responsible for a wealth of fascinating physics. These states include strongly-correlated fractional quantum Hall states which support fractionally-charged excitations in the lowest (N= 0) Landau level, and “bubble” and “stripe” phases responsible for reentrant integer quantum Hall effects and transport anisotropy in higher (N>1) Landau levels. In the N=1 Landau level, fractional quantum Hall states serve as ground states alongside bubble and stripe phases, resulting in striking new physics. My research focuses on the use of resonant inelastic light scattering, resonant Rayleigh scattering, and photoluminescence, to study fundamental properties and the interplay of phases in the N=1 Landau level.
