Non-equilibrium scale invariance and shortcuts to adiabaticity in a one-dimensional Bose gas
We present experimental evidence for scale invariant behaviour of the excitation spectrum in phase-fluctuating quasi-1d Bose gases after a rapid change of the external trapping potential. Probing density correlations in free expansion, we find that the temperature of an initial thermal state scales...
