Superfluidity and sound propagation in disordered Bose gases
Kevin T. Geier, Jeff Maki, Alberto Biella +3
Superfluidity describes the ability of quantum matter to flow without friction. Due to its fundamental role in many transport phenomena, it is crucial to understand the robustness…
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…
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…
