High-resolution spectroscopy of 162Dy Rydberg levels
G. Ferioli, P. Lombardi, P. Sekhar +9
Highly excited Rydberg states of lanthanides are a promising, yet largely unexplored, playground for quantum studies. Here, we report on the first high-resolution spectroscopy of 1…
Flux Magnetism in a Strongly Interacting Dipolar Lattice Supersolid under Tunable Gauge Fields
Michele Miotto, Pietro Lombardi, Giovanni Ferioli +4
Supersolidity and magnetism are fundamental phenomena characterizing strongly correlated matter. Here we unveil a mechanism that directly connects these two regimes and can be expe…
Self-induced Josephson oscillations and self-trapping in a supersolid dipolar quantum gas
Beatrice Donelli, Nicolò Antolini, Giulio Biagioni +8
The Josephson effect characterizes superfluids and superconductors separated by a weak link, the so-called Josephson junction. A recent experiment has shown that Josephson oscillat…
Blue repulsive potential for dysprosium Bose-Einstein condensates
Niccolò Preti, Nicolò Antolini, Giulio Biagioni +4
Short-wavelength repulsive potentials for quantum gases allow to realize new systems and to study new phenomena. Here we report the realization of repulsive optical potentials for…
Mott transition for a Lieb-Liniger gas in a shallow quasiperiodic potential: Delocalization induced by disorder
Hepeng Yao, Luca Tanzi, Laurent Sanchez-Palencia +3
Disorder or quasi-disorder is known to favor the localization in many-body Bose systems. Here in contrast, we demonstrate an anomalous delocalization effect induced by incommensura…
Sub-unity superfluid fraction of a supersolid from self-induced Josephson effect
Giulio Biagioni, Nicolò Antolini, Beatrice Donelli +8
Recently, a new category of superfluids and superconductors has been discovered in various systems. These could be linked to the idea of a supersolid phase, featuring a macroscopic…

G. Biagioni, N. Antolini, A. Alaña +5
We assess experimentally and theoretically the character of the superfluid-supersolid quantum phase transition recently discovered in trapped dipolar quantum gases. We find that on…
Evidence of superfluidity in a dipolar supersolid from non-classical rotational inertia
L. Tanzi, J. G. Maloberti, G. Biagioni +3
A key manifestation of superfluidity in liquids and gases is a reduction of the moment of inertia under slow rotations. Non-classical rotational effects have been searched for a lo…
Supersolid symmetry breaking from compressional oscillations in a dipolar quantum gas
L. Tanzi, S. M. Roccuzzo, E. Lucioni +6
The existence of a paradoxical supersolid phase of matter, possessing the apparently incompatible properties of crystalline order and superfluidity, was predicted 50 years ago. Sol…
Observation of a dipolar quantum gas with metastable supersolid properties
Luca Tanzi, Eleonora Lucioni, Francesca Famà +6
The competition of dipole-dipole and contact interactions leads to exciting new physics in dipolar gases, well-illustrated by the recent observation of quantum droplets and rotons…
Feshbach resonances in potassium Bose-Bose mixtures
L. Tanzi, C. R. Cabrera, J. Sanz +3
We present a detailed study of the scattering properties of ultracold mixtures of bosonic potassium atoms. We locate 20 previously unobserved Feshbach resonances in isotopic 39K-41…

We produce Bose-Einstein condensates of Dy atoms employing an innovative technique based on a resonator-enhanced optical trap that allows efficient loading from the magneto…
Bright soliton to quantum droplet transition in a mixture of Bose-Einstein condensates
P. Cheiney, C. R. Cabrera, J. Sanz +3
Attractive Bose-Einstein condensates can host two types of macroscopic self-bound states of different nature: bright solitons and quantum liquid droplets. Here, we investigate the…

C. R. Cabrera, L. Tanzi, J. Sanz +4
Quantum droplets are small clusters of atoms self-bound by the balance of attractive and repulsive forces. Here we report on the observation of a novel type of droplets, solely sta…
Velocity-dependent quantum phase slips in 1D atomic superfluids
Luca Tanzi, Simona Scaffidi Abbate, Federica Cataldini +5
Quantum phase slips are the primary excitations in one-dimensional superfluids and superconductors at low temperatures but their existence in ultracold quantum gases has not been d…
