Bose–Einstein Condensation in a Dilute, Trapped Gas at Positive Temperature
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–Pitaevskii (GP) limitExpand
Emergence of Non-Abelian Magnetic Monopoles in a Quantum Impurity Problem.
Recently, it was shown that molecules rotating in superfluid helium can be described in terms of the angulon quasiparticles [Phys. Rev. Lett. 118, 095301Expand
Theory of the rotating polaron: Spectrum and self-localization
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 polaron,” which can beExpand
Persistence of Translational Symmetry in the BCS Model with Radial Pair Interaction
We consider the two-dimensional BCS functional with a radial pair interaction. We show that the translational symmetry is not broken in a certain temperature interval below the critical temperature.Expand
Gross–Pitaevskii Limit of a Homogeneous Bose Gas at Positive Temperature
We consider a dilute, homogeneous Bose gas at positive temperature. The system is investigated in the Gross–Pitaevskii limit, where the scattering length a is so small that the interaction energy isExpand
Dynamics and symmetries of a repulsively bound atom pair in an infinite optical lattice
We investigate the dynamics of two bosons trapped in an infinite one-dimensional optical lattice potential within the framework of the Bose-Hubbard model and derive an exact expression for theExpand
Note on a Family of Monotone Quantum Relative Entropies
Given a convex function $${\varphi}$$φ and two hermitian matrices A and B, Lewin and Sabin study in (Lett Math Phys 104:691–705, 2014) the relative entropy defined by $${\mathcal{H}(A,B)={\rm Tr}Expand
Intermolecular forces and correlations mediated by a phonon bath.
Inspired by the possibility to experimentally manipulate and enhance chemical reactivity in helium nanodroplets, we investigate the effective interaction and the resulting correlations between twoExpand
THE FREE ENERGY OF THE TWO-DIMENSIONAL DILUTE BOSE GAS. I. LOWER BOUND
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 $\unicode[STIX]{x1D70C}$ and inverseExpand
