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…
Effective thermalization of a many-body dynamically localized Bose gas
Vincent Vuatelet, Adam Rançon
Dynamical localization is the analog of Anderson localization in momentum space, where the system's energy saturates and the single-particle wave-functions are exponentially locali…
Dynamical localization of interacting bosons in the few-body limit
Radu Chicireanu, Adam Rançon
The quantum kicked rotor is well-known to display dynamical localization in the non-interacting limit. In the interacting case, while the mean-field (Gross-Pitaevskii) approximatio…
Experimental realization of an ideal Floquet disordered system
Clément Hainaut, Adam Rançon, Jean-François Clément +5
The atomic Quantum Kicked Rotor is an outstanding "quantum simulator" for the exploration of transport in disordered quantum systems. Here we study experimentally the phase-shifted…
Thermodynamics of a Bose gas near the superfluid--Mott-insulator transition
A. Rancon, N. Dupuis
We study the thermodynamics near the generic (density-driven) superfluid--Mott-insulator transition in the three-dimensional Bose-Hubbard model using the nonperturbative renormaliz…
