Probing two-subband systems in a quantizing magnetic field with non-equilibrium phonons
arXiv:cond-mat/0301330
Abstract
We propose to use phonon absorption spectroscopy to study many-body gaps and phases of two-subband heterostructures in the quantum Hall regime. Implications of the spin-orbit interaction for phonon absorption in this system are considered.
