Polaron Problems in Ultracold Atoms: Role of a Fermi Sea across Different Spatial Dimensions and Quantum Fluctuations of a Bose Medium
Hiroyuki Tajima, Junichi Takahashi, Simeon I. Mistakidis +2
The notion of a polaron, originally introduced in the context of electrons in ionic lattices, helps us to understand how a quantum impurity behaves when being immersed in and inter…
Extracting non-local inter-polaron interactions from collisional dynamics
Junichi Takahashi, Hiroyuki Tajima, Eiji Nakano +1
This study develops a novel experimental method of deducing the profile of interaction induced between impurities in a trapped gas of ultracold Fermi/Bose atoms, which are often re…
Collisional dynamics of polaronic clouds immersed in a Fermi sea
Hiroyuki Tajima, Junichi Takahashi, Eiji Nakano +1
We propose a new protocol to examine many-polaron properties in a cold atom experiment. Initially, polaronic clouds are prepared around the opposite edges of a majority gas cloud.…
Bose polaron in spherical trap potentials: Spatial structure and quantum depletion
Junichi Takahashi, Ryosuke Imai, Eiji Nakano +1
We investigate how the presence of a localized impurity in a Bose-Einstein condensate of trapped cold atoms that interact with each other weakly and repulsively affects the profile…
