Charged two-dimensional magnetoexciton and two-mode squeezed vacuum states
PACS: 71.35.Ji, 73.20.Mf, 73.43.Lp
Abstract
A novel unitary transformation of the Hamiltonian that allows one to partially separate the center-of-mass motion for charged electron-hole systems in a magnetic field is presented. The two-mode squeezed oscillator states that appear at the intermediate stage of the transformation are used for constructing a trial wave function of a two-dimensional charged magnetoexciton.
