The nambu-goldstone modes of bose-einstein condensed two-dimensional magnetoexcitons
The collective elementary excitations of the two-dimensional (2D) electron-hole systems in a strong perpendicular magnetic field are discussed from the point of view of the Bogoliubov [1]and Goldstone [2] theorems concerning the many-body Hamiltonian with continuous symmetries,continuously degenerat...
