We study the persistent current in a system of SU(N) fermions with repulsive interaction, confined in a ring-shaped potential and pierced by an effective magnetic flux. Several surprising effects emerge. As a combined result of spin correlations, (effective) magnetic flux and interaction, spinons can be created in the ground state such that the elementary flux quantum can change its nature. The persistent current landscape is affected dramatically by these changes. In particular, it displays a… 

Persistent currents in a strongly interacting multicomponent Bose gas on a ring

. We consider a two-component Bose-Bose mixture at strong repulsive interactions in a tightly confining, one-dimensional ring trap and subjected to an artificial gauge field. By employing the Bethe

Enhancement of chiral edge currents in ($d$+1)-dimensional atomic Mott-band hybrid insulators

We consider the effect of a local interatomic repulsion on synthetic ladders and heterostructures where a discrete synthetic dimension is created by Raman processes on top of SU ( N ) symmetric

Mimicking Multiorbital Systems with SU(N) Atoms: Hund’s Physics and Beyond

The physics of many interesting correlated materials can be captured by multiorbital Hubbard models, where conduction electrons feature an additional orbital degree of freedom. The multiorbital

Variational quantum eigensolver for SU(N) fermions

Variational quantum algorithms aim at harnessing the power of noisy intermediate-scale quantum (NISQ) computers, by using a classical optimizer to train a parameterized quantum circuit to solve

The persistent current in microscopic and mesoscopic Hubbard rings threaded with magnetic flux is studied and it is found that as the flux is increased by one quantum, a magnon hole traverses the magnon sea, generating a periodicity of 1/N c in the persistent current, but with no changes in the overall spin magnetization.

Temperature-Dependent Periodicity of the Persistent Current in Strongly Interacting Systems.

The persistent current in small isolated rings enclosing magnetic flux is the current circulating in equilibrium in the absence of an external excitation. While initially studied in superconducting

Persistent Currents in Rings of Ultracold Fermionic Atoms.

We have produced persistent currents of ultracold fermionic atoms trapped in a ring, with lifetimes greater than 10 sec in the strongly interacting regime. These currents remain stable well into the

Rise and Fall of a Bright Soliton in an Optical Lattice.

We study an ultracold atomic gas with attractive interactions in a one-dimensional optical lattice. We find that its excitation spectrum displays a quantum soliton band, corresponding to N-particle

Direct Probing of the Mott Crossover in the SU(N) Fermi-Hubbard Model

We report on a detailed experimental investigation of the equation of state (EoS) of the three-dimensional Fermi-Hubbard model (FHM) in its generalized SU(N)-symmetric form, using a degenerate

High-momentum tails as magnetic structure probes for strongly-correlated SU(κ) fermionic mixtures in one-dimensional traps

A universal k −4 decay of the large-momentum tails of the momentum distribution, fixed by Tan's contact coefficients, constitutes a direct signature of strong correlations in a short-range


We investigate the metal-insulator transition of the one-dimensional SU(N) Hubbard model for repulsive interaction. Using the bosonization approach a Mott transition in the charge sector at

Ultracold Fermi gases with emergent SU(N) symmetry

Recent experimental and theoretical progress on ultracold alkaline-earth Fermi gases with emergent SU(N) symmetry is reviewed and some of the challenges that lie ahead for the realization of such phases such as reaching the temperature scale required to observe magnetic and more exotic quantum orders are discussed.
