Polarons, dressed molecules and itinerant ferromagnetism in ultracold Fermi gases

P Massignan, M Zaccanti… - Reports on Progress in …, 2014 - iopscience.iop.org
In this review, we discuss the properties of a few impurity atoms immersed in a gas of
ultracold fermions—the so-called Fermi polaron problem. On one hand, this many-body …

Universal many-body response of heavy impurities coupled to a Fermi sea: a review of recent progress

R Schmidt, M Knap, DA Ivanov, JS You… - Reports on Progress …, 2018 - iopscience.iop.org
In this report we discuss the dynamical response of heavy quantum impurities immersed in a
Fermi gas at zero and at finite temperature. Studying both the frequency and the time …

A Vashisht, I Amelio, L Vanderstraeten… - ar** a lattice-trapped bosonic species with impurities: From ground state properties to correlated tunneling dynamics
K Keiler, SI Mistakidis, P Schmelcher - New Journal of Physics, 2020 - iopscience.iop.org
We investigate the ground state properties and the nonequilibrium dynamics of a lattice
trapped bosonic mixture consisting of an impurity species and a finite-sized medium. For the …

Mobile impurities interacting with a few one-dimensional lattice bosons

We report a comprehensive study of the ground-state properties of one and two bosonic
impurities immersed in small one-dimensional optical lattices loaded with a few interacting …

Induced pairing of fermionic impurities in a one-dimensional strongly correlated Bose gas

M Pasek, G Orso - Physical Review B, 2019 - APS
We investigate numerically the problem of few (one or two) noninteracting spin-1/2 fermions
in a shallow harmonic trap coupled via contact repulsive interactions to a uniform one …
