Fermionic quantum processing with programmable neutral atom arrays
Daniel González-Cuadra, Dolev Bluvstein, Marcin Kalinowski +10
Simulating the properties of many-body fermionic systems is an outstanding computational challenge relevant to material science, quantum chemistry, and particle physics. Although q…
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…
Quench dynamics of quasi-periodic systems exhibiting Rabi oscillations of two-level integrals of motion
Leonardo Benini, Piero Naldesi, Rudolf A. Römer +1
The elusive nature of localized integrals of motion (or l-bits) in disordered quantum systems lies at the core of some of their most prominent features, i.e. emergent integrability…
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.…
Loschmidt echo singularities as dynamical signatures of strongly localized phases
Leonardo Benini, Piero Naldesi, Rudolf A. Römer +1
Quantum localization (single-body or many-body) comes with the emergence of local conserved quantities -- whose conservation is precisely at the heart of the absence of transport t…
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…
Algebraic Localization from Power-Law Interactions in Disordered Quantum Wires
Thomas Botzung, Davide Vodola, Piero Naldesi +3
We analyze the effects of disorder on the correlation functions of one-dimensional quantum models of fermions and spins with long-range interactions that decay with distance …
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…
