Observation of the Sliding Phase in 8 7 Rb
Abstract
We present observations of the sliding phase in disordered ultracold 87Rb. For systems with a,b,c axis, and 1D disorder along c-axis, the sliding phase is when ``c-axis superfluid response disappears, while the system remains superfluid in the a and b directions''. We generate the sliding phase potential using a disordered optical lattice generated by our high-bandwidth arbitrary lattice apparatus. Our findings show three phase crossover regimes at distinct temperatures, which compares favourably to theoretical predictions. In addition, we present data suggesting the presence of a Griffiths phase. David Pekker et al., Phys. Rev. Lett. 105, 085302 (2010).
