A second order upper bound to the free energy of the two dimensional Bose gas

Florian Haberberger, Lukas Junge

We consider a two-dimensional Bose gas in the dilute regime where is small. For temperatures below the Berezinskii-Kosterlitz-Thouless critical temperature, we derive an exp…

Propagation of Condensation via Neumann Localization in the Dilute Bose Gas

Lukas Junge

We prove a Neumann localization inequality for the Laplacian that includes a spectral gap. This result is obtained by partitioning a cube into overlapping families of subcubes and…

Derivation of Hartree theory for two-dimensional attractive Bose gases in almost Gross-Pitaevskii regime

Lukas Junge, François Louis Antoine Visconti

We study the ground state energy of trapped two-dimensional Bose gases with mean-field type interactions that can be attractive. We prove the stability of second kind of the many-b…

The free energy of dilute Bose gases at low temperatures interacting via strong potentials

S. Fournais, L. Junge, T. Girardot +3

We consider a dilute Bose gas in the thermodynamic limit and prove a lower bound on the free energy for low temperatures which is in agreement with the conjecture of Lee-Huang-Yang…

Ground state energy of a dilute Bose gas with three-body hard-core interactions

Lukas Junge, François Louis Antoine Visconti

We consider a gas of bosons interacting through a three-body hard-core potential in the thermodynamic limit. We derive an upper bound on the ground state energy of the system at th…

Lower bounds on the energy of the Bose gas

Søren Fournais, Theotime Girardot, Lukas Junge +2

We present an overview of the approach to establish a lower bound to the ground state energy for the dilute, interacting Bose gas in a periodic box. In this paper the size of the b…
