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…

From Feynman-Vernon to Wiener Stochastic Path Integral
Antonio Camurati, Felipe Sobrero, Bruno Suassuna +1
We establish a direct connection between the Feynman-Vernon path integral formalism for open quantum systems and the Wiener path integral used in classical stochastic dynamics. By…
