Massive particle interferometry with lattice solitons
Piero Naldesi, Juan Polo, Peter D. Drummond +4
We discuss an interferometric scheme employing interference of bright solitons formed as specific bound states of attracting bosons on a lattice. We revisit the proposal of Castin…
Fermionic correlation functions from randomized measurements in programmable atomic quantum devices
Piero Naldesi, Andreas Elben, Anna Minguzzi +3
We provide a measurement protocol to estimate 2- and 4-point fermionic correlations in ultra-cold atom experiments. Our approach is based on combining random atomic beam splitter o…
Massive particle interferometry with lattice solitons: robustness against ionization
Piero Naldesi, Peter D. Drummond, Vanja Dunjko +2
We revisit the proposal of Castin and Weiss [Phys. Rev. Lett. vol. 102, 010403 (2009)] for using the scattering of a quantum matter-wave soliton on a barrier in order to create a c…
Single-particle versus many-body phase coherence in an interacting Fermi gas
Giovanni Pecci, Piero Naldesi, Anna Minguzzi +1
In quantum mechanics, each particle is described by a complex valued wave-function characterized by amplitude and phase. When many particles interact each other, cooperative phenom…
The quantum solitons atomtronic interference device
Juan Polo, Piero Naldesi, Anna Minguzzi +1
We study a quantum many-body system of attracting bosons confined in a ring-shaped potential and interrupted by a weak link. With such architecture, the system defines atomtronic q…
Probing the BCS-BEC crossover with persistent currents
Giovanni Pecci, Piero Naldesi, Luigi Amico +1
We study the persistent currents of an attractive Fermi gas confined in a tightly-confining ring trap and subjected to an artificial gauge field all through the BCS-BEC crossover.…
Exact results for persistent currents of two bosons in a ring lattice
Juan Polo, Piero Naldesi, Anna Minguzzi +1
We study the ground state of two interacting bosonic particles confined in a ring-shaped lattice potential and subjected to a synthetic magnetic flux. The system is described by th…
Enhancing sensitivity to rotations with quantum solitonic currents
Piero Naldesi, Juan Polo Gomez, Vanja Dunjko +4
Quantum mechanics is characterized by quantum coherence and entanglement. After having discovered how these fundamental concepts govern physical reality, scientists have been devot…
Raise and fall of a bright soliton in an optical lattice
Piero Naldesi, Juan Polo Gomez, Anna Minguzzi +3
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, correspond…
Multi-speed prethermalization in spin models with power-law decaying interactions
Irénée Frérot, Piero Naldesi, Tommaso Roscilde
The relaxation of uniform quantum systems with finite-range interactions after a quench is generically driven by the ballistic propagation of long-lived quasi-particle excitations…
Bound states and expansion dynamics of interacting bosons on a one-dimensional lattice
Cristian Degli Esposti Boschi, Elisa Ercolessi, Loris Ferrari +3
The expansion dynamics of bosonic gases in optical lattices has recently been the focus of increasing attention, both experimental and theoretical. We consider, by means of numeric…
