The free energy of the two-dimensional dilute Bose gas. II. Upper bound
Simon Mayer, Robert Seiringer
We prove an upper bound on the free energy of a two-dimensional homogeneous Bose gas in the thermodynamic limit. We show that for and the free energy per…
The free energy of the two-dimensional dilute Bose gas. I. Lower bound
Andreas Deuchert, Simon Mayer, Robert Seiringer
We prove a lower bound for the free energy (per unit volume) of the two-dimensional Bose gas in the thermodynamic limit. We show that the free energy at density and inverse tem…
Gross-Pitaevskii Limit of a Homogeneous Bose Gas at Positive Temperature
Andreas Deuchert, Robert Seiringer
We consider a dilute, homogeneous Bose gas at positive temperature. The system is investigated in the Gross-Pitaevskii (GP) limit, where the scattering length is so small that…
Theory of the Rotating Polaron: Spectrum and Self-Localization
Enderalp Yakaboylu, Bikashkali Midya, Andreas Deuchert +2
We study a quantum impurity possessing both translational and internal rotational degrees of freedom interacting with a bosonic bath. Such a system corresponds to a `rotating polar…
Bose-Einstein Condensation in a Dilute, Trapped Gas at Positive Temperature
Andreas Deuchert, Robert Seiringer, Jakob Yngvason
We consider an interacting, dilute Bose gas trapped in a harmonic potential at a positive temperature. The system is analyzed in a combination of a thermodynamic and a Gross-Pitaev…
Emergence of non-abelian magnetic monopoles in a quantum impurity problem
Enderalp Yakaboylu, Andreas Deuchert, Mikhail Lemeshko
Recently it was shown that molecules rotating in superfluid helium can be described in terms of the angulon quasiparticles (Phys. Rev. Lett. 118, 095301 (2017)). Here we demonstrat…
