Optical excitations in compressible and incompressible two-dimensional electron liquids
Optical excitations in compressible and incompressible two-dimensional electron liquids
Optically generated electron-hole pairs can probe strongly correlated electronic matter, or, by forming exciton-polaritons within an optical cavity, give rise to photonic nonlinearities. The present paper theoretically studies the properties of electron-hole pairs in a two-dimensional electron liquid in the fractional quantum Hall regime. In particular, we quantify the effective …
