Weak Edgeworth expansion for the mean-field interacting Bose gas
Lea Boßmann, Sören Petrat
We consider the ground state and the low-energy excited states of a system of identical bosons with interactions in the mean-field scaling regime. For the ground state, we deri…

Low-energy spectrum and dynamics of the weakly interacting Bose gas
Lea Boßmann
We consider a gas of N bosons with interactions in the mean-field scaling regime. We review the proof of an asymptotic expansion of its low-energy spectrum, eigenstates and dynamic…
