Upper bound for the ground state energy of a dilute Bose gas of hard spheres
Giulia Basti, Serena Cenatiempo, Alessandro Giuliani +3
We consider a gas of bosons interacting through a hard-sphere potential with radius in the thermodynamic limit. We derive a simple upper bound for the ground state energ…

Energy expansions for dilute Bose gases from local condensation results: a review of known results
Giulia Basti, Cristina Caraci, Serena Cenatiempo
Non-relativistic interacting bosons at zero temperature, in two and three dimensions, are expected to exhibit a fascinating critical phase, famously known as condensate phase. Even…

Renormalization theory of a two dimensional Bose gas: quantum critical point and quasi-condensed state
Serena Cenatiempo, Alessandro Giuliani
We present a renormalization group construction of a weakly interacting Bose gas at zero temperature in the two-dimensional continuum, both in the quantum critical regime and in th…
