Quasiparticle nature of the Bose polaron at finite temperature
G Pascual, J Boronat - Physical review letters, 2021 - APS
The Bose polaron has attracted theoretical and experimental interest because the mobile
impurity is surrounded by a bath that undergoes a superfluid-to-normal phase transition …
