Abstract
- We have studied the collective excitation of Bose-Einstein condensate of short range weak interacting atoms with spin-orbit coupling (SOC) in two dimension in liquid phase. In our study, we have included Rashba, Dresselhaus SOC as well as Raman SOC. The study of Bogoliubov excitation shows that in small interaction case only phonon modes are present and for higher interactions roton modes start to appear. Energy spectra contain two roton modes in the system relatively strong interacting atomic system.
