Oxide layer formation prevents deteriorating ion migration in thermoelectric CuSe during operation in air
Rasmus S. Christensen, Peter S. Thorup, Lasse R. Jørgensen +4
CuSe is a mixed ionic-electronic conductor with outstanding thermoelectric performance originally envisioned for space missions. Applications were discontinued due to material…
Finite-temperature behavior of the Bose polaron
Jesper Levinsen, Meera M. Parish, Rasmus S. Christensen +2
We consider a mobile impurity immersed in a Bose gas at finite temperature. Using perturbation theory valid for weak coupling between the impurity and the bosons, we derive analyti…
Observation of Attractive and Repulsive Polarons in a Bose-Einstein Condensate
Nils B. Jørgensen, Lars Wacker, Kristoffer T. Skalmstang +5
The problem of an impurity particle moving through a bosonic medium plays a fundamental role in physics. However, the canonical scenario of a mobile impurity immersed in a Bose-Ein…
