Analyzing a Bose polaron across resonant interactions
L. A. Peña Ardila, N. B. Jörgensen, T. Pohl +3
Recently, two independent experiments reported the observation of long-lived polarons in a Bose-Einstein condensate, providing an excellent setting to study the generic scenario of…
Dropping an impurity into a Chern insulator: a polaron view on topological matter
A. Camacho-Guardian, N. Goldman, P. Massignan +1
We investigate the properties of an impurity particle interacting with a Fermi gas in a Chern-insulating state. The interaction leads to the formation of an exotic polaron, which c…
Dilute Fluid Governed by Quantum Fluctuations
Nils B. Jørgensen, Georg M. Bruun, Jan J. Arlt
Understanding the effects of interactions in complex quantum systems beyond the mean-field paradigm constitutes a fundamental problem in physics. Here, we show how the atom numbers…
Induced -wave pairing in Bose-Fermi mixtures
Jami J. Kinnunen, Zhigang Wu, Georg M. Bruun
Cooper pairing caused by an induced interaction represents a paradigm in our description of fermionic superfluidity. Here, we present a strong coupling theory for the critical temp…
Critical slowdown of non-equilibrium polaron dynamics
Kristian Knakkergaard Nielsen, Luis A. Peña Ardila, Georg M. Bruun +1
We study the quantum dynamics of a single impurity following its sudden immersion into a Bose-Einstein condensate. The ensuing formation of the Bose polaron in this general setting…
Stabilising Fulde-Ferrel-Larkin-Ovchinnikov Superfluidity with long-range Interactions in a mixed dimensional Bose-Fermi System
Jonatan Melkær Midtgaard, Georg M. Bruun
We analyse the stability of inhomogeneous superfluid phases in a system consisting of identical fermions confined in two layers that are immersed in a Bose-Einstein condensate (BEC…
