Unconditional mechanical squeezing via back-action evading measurements and non-optimal feedback control
Antonio Di Giovanni, Matteo Brunelli, Marco G. Genoni
Backaction-evading (BAE) measurements of a mechanical resonator, by continuously monitoring a single quadrature of motion, can achieve precision below the zero-point uncertainty. W…
Cavity optomechanics assisted by optical coherent feedback
Alfred Harwood, Matteo Brunelli, Alessio Serafini
We consider a wide family of optical coherent feedback loops acting on an optomechanical system operating in the linearized regime. We assess the efficacy of such loops in improvin…
Correspondence between non-Hermitian topology and directional amplification in the presence of disorder
Clara C. Wanjura, Matteo Brunelli, Andreas Nunnenkamp
In order for non-Hermitian (NH) topological effects to be relevant for practical applications, it is necessary to study disordered systems. In the absence of disorder, certain driv…
Assessing the role of initial correlations in the entropy production rate for non-equilibrium harmonic dynamics
Giorgio Zicari, Matteo Brunelli, Mauro Paternostro
Entropy production provides a general way to state the second law of thermodynamics for non-equilibrium scenarios. In open quantum system dynamics, it also serves as a useful quant…
Stroboscopic quantum optomechanics
Matteo Brunelli, Daniel Malz, Albert Schliesser +1
We consider an optomechanical cavity that is driven stroboscopically by a train of short pulses. By suitably choosing the inter-pulse spacing we show that ground-state cooling and…
Quantum correlations in -symmetric systems
Federico Roccati, Salvatore Lorenzo, G. Massimo Palma +3
We study the dynamics of correlations in a paradigmatic setup to observe -symmetric physics: a pair of coupled oscillators, one subject to a gain one to a loss. Start…
