Open AccessThe impact of different unravelings in a monitored system of free fermions
We consider a free-fermion chain undergoing dephasing, described by two different random-measurement protocols (unravelings): a quantum-state-diffusion and a quantum-jump one. Both protocols keep the state in ...

Open AccessUltra-stable charging of fast-scrambling SYK quantum batteries
Collective behavior strongly influences the charging dynamics of quantum batteries (QBs). Here, we study the impact of nonlocal correlations on the energy stored in a system of N QBs. A unitary charging protocol ...

Open AccessBallistic transport and boundary resistances in inhomogeneous quantum spin chains
Transport phenomena are central to physics, and transport in the many-body and fully-quantum regime is attracting an increasing amount of attention. It has been recently revealed that some quantum spin chains ...

Strongly Correlated Polaritons in Nonlinear Cavity Arrays
Arrays of coupled QED cavities have been proposed as promising candidates to study hybrid many-body states of light and matter in a controlled way. The rich scenario emerging in these systems stems from the in...

Open AccessLocal quantum thermal susceptibility
Thermodynamics relies on the possibility to describe systems composed of a large number of constituents in terms of few macroscopic variables. Its foundations are rooted into the paradigm of statistical mechan...

Open AccessMagnetic crystals and helical liquids in alkaline-earth fermionic gases
The joint action of a magnetic field and of interactions is crucial for the appearance of exotic quantum phenomena, such as the quantum Hall effect. Owing to their rich nuclear structure, equivalent to an addi...

Open AccessPhase diagram of a QED-cavity array coupled via a N-type level scheme
We study the zero-temperature phase diagram of a one-dimensional array of QED cavities where, besides the single-photon hop**, an additional coupling between neighboring cavities is mediated by an N-type four-l...
