Few-body collective excitations beyond Kohn's theorem in quantum Hall systems

15 Jul 2016 Wooten R. E. Yan B. Greene Chris H.

A relative coordinate breathing mode in the quantum Hall system is predicted to exist with different behavior under either Coulomb or dipole-dipole interactions. While Kohn's theorem predicts that any relative coordinate interaction will fail to alter the center of mass energy spectrum, it can affect excitations in the relative coordinates... (read more)
