Loss induced collective mode in one-dimensional Bose gases
Jeff Maki, Lorenzo Rosso, Leonardo Mazza +1
We show that two-body losses induce a collective excitation in a harmonically trapped one-dimensional Bose gas, even in the absence of a quench in the trap or any other external pe…
Effects of atom losses on a one-dimensional lattice gas of hardcore bosons
François Riggio, Lorenzo Rosso, Dragi Karevski +1
Atom losses occur naturally during cold atoms experiments. Since this phenomenon is unavoidable, it is important to understand its effect on the remaining atoms. Here we study a ga…
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…
Dissipative flow equations
Lorenzo Rosso, Fernando Iemini, Marco Schirò +1
We generalize the theory of flow equations to open quantum systems focusing on Lindblad master equations. We introduce and discuss three different generators of the flow that trans…
