Observation of universal non-Gaussian statistics of the order parameter across a continuous phase transition
Maxime Allemand, Géraud Dupuy, Paul Paquiez +5
Second-order phase transitions are characterised by critical scaling and universality. The singular behaviour of thermodynamic quantities at the transition, in particular, is deter…
Strong-coupling RPA theory of a Bose gas near the superfluid--Mott-insulator transition: universal thermodynamics and two-body contact
Nicolas Dupuis, Moksh Bhateja, Adam Rançon
We present a strong-coupling expansion of the Bose-Hubbard model based on a mean-field treatment of the hopping term, while onsite fluctuations are taken into account exactly. This…
Two-body contact of a Bose gas near the superfluid--Mott-insulator transition
Moksh Bhateja, Nicolas Dupuis, Adam Rançon
The two-body contact is a fundamental quantity of a dilute Bose gas that relates the thermodynamics to the short-distance two-body correlations. For a Bose gas in an optical lattic…
