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…
Solitary waves of attracting SU(N) fermions
Aysha Alsubaihi, Wayne J. Chetcuti, Frederic Chevy +2
We study the formation, dynamics, and disorder robustness of bound states in attractively interacting SU(N) fermions on a one-dimensional ring lattice. Using exact diagonalization…
Lattice Unitarity: Saturated Collisional Resistivity in Hubbard Metals
Frank Corapi, Robyn T. Learn, Benjamin Driesen +5
We investigate the interaction-induced resistivity of ultracold fermions in a three-dimensional optical lattice. In situ observations of transport dynamics enable the determination…
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,…
Experimental realization of a SU(3) color-orbit coupling in an ultracold gas
Chetan S. Madasu, Chirantan Mitra, Lucas Gabardos +6
Spin-orbit interaction couples the spin of a particle to its motion and leads to spin-induced transport phenomena such as spin-Hall effects and Chern insulators. In this work, we e…
Exploring beyond-mean-field logarithmic divergences in Fermi-polaron energy
Ragheed Alhyder, Frédéric Chevy, Xavier Leyronas
We perform a diagrammatic analysis of the energy of a mobile impurity immersed in a strongly interacting two component Fermi gas to second order in the impurity-bath interaction. T…
