A dynamical theory for one-dimensional fermions with strong two-body losses: universal non-Hermitian Zeno physics and spin-charge separation
Lorenzo Rosso, Alberto Biella, Jacopo De Nardis +1
We study an interacting one-dimensional gas of spin-1/2 fermions with two-body losses. The dynamical phase diagram that characterises the approach to the stationary state displays…
Eightfold way to dark states in SU(3) cold gases with two-body losses
Lorenzo Rosso, Leonardo Mazza, Alberto Biella
We study the quantum dynamics of a one-dimensional SU(3)-symmetric system of cold atoms in the presence of two-body losses. We exploit the representation theory of SU(3), the so-ca…
The one-dimensional Bose gas with strong two-body losses: the effect of the harmonic confinement
Lorenzo Rosso, Alberto Biella, Leonardo Mazza
We study the dynamics of a one-dimensional Bose gas in presence of strong two-body losses. In this dissipative quantum Zeno regime, the gas fermionises and its dynamics can be desc…
One-dimensional spin-1/2 fermionic gases with two-body losses: weak dissipation and spin conservation
Lorenzo Rosso, Davide Rossini, Alberto Biella +1
We present a theoretical analysis of the dynamics of a one-dimensional spin-1/2 fermionic gas subject to weak two-body losses. Our approach highlights the crucial role played by sp…
Strong correlations in lossy one-dimensional quantum gases: from the quantum Zeno effect to the generalized Gibbs ensemble
Davide Rossini, Alexis Ghermaoui, Manel Bosch Aguilera +5
We consider strong two-body losses in bosonic gases trapped in one-dimensional optical lattices. We exploit the separation of time scales typical of a system in the many-body quant…
Pairing in spin chains and spinless fermions with next-nearest neighbour interactions
Lorenzo Gotta, Leonardo Mazza, Pascal Simon +1
We investigate the phase diagrams of a one-dimensional lattice model of fermions and of a spin chain with interactions extending up to next-nearest neighbour range. In particular,…
Fusion channels of non-Abelian anyons from angular-momentum and density-profile measurements
Elia Macaluso, Tommaso Comparin, Leonardo Mazza +1
We present a method to characterize non-Abelian anyons that is based only on static measurements and that does not rely on any form of interference. For geometries where the anyoni…
Spin-gap spectroscopy in a bosonic flux ladder
Marcello Calvanese Strinati, Fabrice Gerbier, Leonardo Mazza
Ultracold bosonic atoms trapped in a two-leg ladder pierced by a magnetic field provide a minimal and quasi-one-dimensional instance to study the interplay between orbital magnetis…
Laughlin-like states in bosonic and fermionic atomic synthetic ladders
Marcello Calvanese Strinati, Eyal Cornfeld, Davide Rossini +5
The combination of interactions and static gauge fields plays a pivotal role in our understanding of strongly-correlated quantum matter. Cold atomic gases endowed with a synthetic…
Dissipative topological superconductors in number-conserving systems
Fernando Iemini, Davide Rossini, Rosario Fazio +2
We discuss the dissipative preparation of p-wave superconductors in number-conserving one-dimensional fermionic systems. We focus on two setups: the first one entails a single wire…
Synthetic gauge fields in synthetic dimensions: Interactions and chiral edge modes
Simone Barbarino, Luca Taddia, Davide Rossini +2
Synthetic ladders realized with one-dimensional alkaline-earth(-like) fermionic gases and subject to a gauge field represent a promising environment for the investigation of quantu…

Leonardo Mazza, Monika Aidelsburger, Hong-Hao Tu +2
We consider a spin-1/2 fermionic ladder with spin-orbit coupling and a perpendicular magnetic field, which shares important similarities with topological superconducting wires. We…

Single-site- and single-atom-resolved measurement of correlation functions
Manuel Endres, Marc Cheneau, Takeshi Fukuhara +8
Correlation functions play an important role for the theoretical and experimental characterization of many-body systems. In solid-state systems, they are usually determined through…
Observation of Correlated Particle-Hole Pairs and String Order in Low-Dimensional Mott Insulators
M. Endres, M. Cheneau, T. Fukuhara +8
Quantum phases of matter are characterized by the underlying correlations of the many-body system. Although this is typically captured by a local order parameter, it has been shown…
