Benchmarking the fermionic quasi-1D many-body problem

Ekaterina Gradova, Fr{é}d{é}ric Chevy

We investigate the validity of effective one-dimensional models for quasi-1D fermionic systems by benchmarking a coupled-channel approach against the exact low-energy theory derive…

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,…
