Microsecond-scale high-survival and number-resolved detection of ytterbium atom arrays
Alessandro Muzi Falconi, Riccardo Panza, Sara Sbernardori +5
Scalable atom-based quantum platforms for simulation, computing, and metrology require fast high-fidelity, low-loss imaging of individual atoms. Standard fluorescence detection met…
Engineering the Kondo impurity problem with alkaline-earth atom arrays
Adriano Amaricci, Andrea Richaud, Massimo Capone +2
We propose quantum simulation experiments of the Kondo impurity problem using cold alkaline-earth(-like) atoms (AEAs) in a combination of optical lattice and optical tweezer potent…
Dynamical formation of multiple quantum droplets in a Bose-Bose mixture
L. Cavicchioli, C. Fort, F. Ancilotto +3
We report on the formation of multiple quantum droplets in a heteronuclear K-Rb mixture released in an optical waveguide. By a sudden change of the interspecies inter…
Breathing mode of a quantum droplet in a quasi-one-dimensional dipolar Bose gas
Edmond Orignac, Stefania De Palo, Luca Salasnich +1
We investigate the breathing mode and the stability of a quantum droplet in a tightly trapped one-dimensional dipolar gas of bosonic atoms. When the droplet with a flat-top density…
Breakup of quantum liquid filaments into droplets
Francesco Ancilotto, Manuel Barranco, Marti Pi
We have investigated how the Rayleigh-Plateau instability of a filament made of a 41K-87Rb self-bound mixture may lead to an array of identical quantum droplets, with typical break…
Effect of transverse confinement on a quasi-one dimensional dipolar Bose gas
Stefania De Palo, Edmond Orignac, Roberta Citro +1
We study a gas of bosonic dipolar atoms in the presence of a transverse harmonic trapping potential by using an improved variational Bethe ansatz, which includes the transverse wid…
Massive superfluid vortices and vortex necklaces on a planar annulus
Matteo Caldara, Andrea Richaud, Massimo Capone +1
We study a superfluid in a planar annulus hosting vortices with massive cores. An analytical point-vortex model shows that the massive vortices may perform radial oscillations on t…
Mass-driven vortex collisions in flat superfluids
Andrea Richaud, Giacomo Lamporesi, Massimo Capone +1
Quantum vortices are often endowed with an effective inertial mass, due, for example, to massive particles in their cores. Such "massive vortices" display new phenomena beyond the…
Enhancement of chiral edge currents in (+1)-dimensional atomic Mott-band hybrid insulators
Matteo Ferraretto, Andrea Richaud, Lorenzo Del Re +2
We consider the effect of a local interatomic repulsion on synthetic heterostructures where a discrete synthetic dimension is created by Raman processes on top of -symmetric…
A full view on the dynamics of an impurity coupled to two one-dimensional fermionic baths
Martino Stefanini, Massimo Capone, Alessandro Silva
We consider a model for the motion of an impurity interacting with two parallel, one-dimensional (bosonized) fermionic baths. The impurity is able to move along any of the baths, a…
Vortices in quantum droplets of heteronuclear Bose mixtures
Matteo Caldara, Francesco Ancilotto
We have theoretically investigated the structure of spinning self-bound droplets made of K-Rb Bose mixture by solving the Gross-Pitaevskii equation including beyond-m…
Flavour-selective localization in interacting lattice fermions via SU(N) symmetry breaking
Daniele Tusi, Lorenzo Franchi, Lorenzo Francesco Livi +10
A large repulsion between particles in a quantum system can lead to their localization, as it happens for the electrons in Mott insulating materials. This paradigm has recently bra…
Quantum simulating the electron transport in quantum cascade laser structures
Andrea Trombettoni, Francesco Scazza, Francesco Minardi +5
We propose to use ultracold fermionic atoms in one-dimensional optical lattices to quantum simulate the electronic transport in quantum cascade laser (QCL) structures. The competit…
A dual-species Bose-Einstein condensate with attractive interspecies interactions
Alessia Burchianti, Chiara D'Errico, Marco Prevedelli +5
We report on the production of a K-Rb dual-species Bose-Einstein condensate with tunable interspecies interaction and we study the mixture in the attractive regime, i…
Rotating mixed He-He nanodroplets
Marti Pi, Francesco Ancilotto, Jose' Maria Escartin +2
Mixed He-He droplets created by hydrodynamic instability of a cryogenic fluid-jet may acquire angular momentum during their passage through the nozzle of the experimental a…
Topological phase transitions in four dimensions
Nicolò Defenu, Andrea Trombettoni, Dario Zappalà
We show that four-dimensional systems may exhibit a topological phase transition analogous to the well-known Berezinskii-Kosterlitz-Thouless vortex unbinding transition in two-dime…
Reaching the quantum Hall regime with rotating Rydberg-dressed atoms
Michele Burrello, Igor Lesanovsky, Andrea Trombettoni
Despite the striking progress in the field of quantum gases, one of their much anticipated application -- the simulation of quantum Hall states -- remains elusive: all experimental…
Quantum fluctuations beyond the Gutzwiller approximation in the Bose-Hubbard model
Fabio Caleffi, Massimo Capone, Chiara Menotti +2
We develop a quantum many-body theory of the Bose-Hubbard model based on the canonical quantization of the action derived from a Gutzwiller mean-field ansatz. Our theory is a syste…
Effective expression of the Lee-Huang-Yang energy functional for heteronuclear mixtures
F. Minardi, F. Ancilotto, A. Burchianti +3
We consider a homogeneous heteronuclear Bose mixture with contact interactions at the mean-field collapse, i.e. with interspecies attraction equal to the mean geometrical intraspec…
Observation of Quantum Droplets in a Heteronuclear Bosonic Mixture
C. D'Errico, A. Burchianti, M. Prevedelli +5
We report on the formation of heteronuclear quantum droplets in an attractive bosonic mixture of 41K and 87Rb. We observe long-lived self-bound states, both in free space and in an…

K. Xhani, E. Neri, L. Galantucci +9
We study the onset of dissipation in an atomic Josephson junction between Fermi superfluids in the molecular Bose-Einstein condensation limit of strong attraction. Our simulations…

Luca Arceci, Lucas Kohn, Angelo Russomanno +1
We investigate the effect of dissipation from a thermal environment on topological pumping in the periodically-driven Rice-Mele model. We report that dissipation can improve the ro…
Relaxation of Shannon entropy for trapped interacting bosons with dipolar interactions
S. Bera, S. K. Haldar, B. Chakrabarti +2
We study the dynamics of dipolar bosons in an external harmonic trap. We monitor the time evolution of the occupation in the natural orbitals and normalized first- and second-order…
Supersolid behaviour of a dipolar Bose-Einstein condensate confined in a tube
