Response of a classical mesoscopic oscillator to a two-level quantum system
Felipe Sobrero, Luca Abrahão, Thiago Guerreiro +1
We investigate the dynamics of a classical mechanical oscillator coupled to the simplest quantum system, a single qubit. Using the Feynman-Vernon influence functional formalism, we…

All-optical saddle trap as a platform for mesoscopic quantum experiments
Pedro V. Paraguassú, Luca Abrahão, Daniel Tandeitnik +3
We investigate the quantum dynamics of a levitated nanoparticle in a structured light rotating saddle-like optical potential consisting of a superposition of Gaussian and Laguerre-…

Quantum-induced Stochastic Optomechanical Dynamics
Pedro V. Paraguassú, Luca Abrahão, Thiago Guerreiro
We study the effective stochastic dynamics of a semiclassical probe induced by linear optomechanical interactions with a quantum oscillator. Quantum fluctuations lead to state-depe…
