SUMMARY:Broken summetries in spin-orbit coupled Bose-Einstein condensates

DESCRIPTION:In the seminar I will focus on the symmetries characterizing t
 he 1D spin-orbit coupled hamiltonian first realized experimentally by the 
 team\nof Ian Spielman at Nist. The nature of the new quantum phases  and  
  their\ndynamic properties will be discussed. Special focus will be given 
 on the recently observed  rotonic excitation\,  which follows from the bre
 aking of time reversal and parity  symmetry\,  on the emergence of stripes
  which follows from the spontaneous breaking of translational invariance\,
  and on the dynamic instability of large amplitude oscillations  which is 
 the consequence of the violation of Galielan invariance.\n
