Downfolding a quantum many-body system: the quasi-1D Fermi polaron

Lovro Anto Barišić, Giuliano Orso, Frédéric Chevy +1

We investigate the properties of an impurity immersed in an ensemble of spin-polarized fermions confined in a tight quantum wire. We use a non-perturbative variational approach tha…

Quasi-particle residue and charge of the one-dimensional Fermi polaron

Giuliano Orso, Lovro Barišić, Ekaterina Gradova +2

We consider a mobile impurity coupled to an ideal Fermi gas in one spatial dimension through an attractive contact interaction. We calculate the quasi-particle residue exactly,…
