Testing classical-quantum gravity with geodesic deviation

Tomoya Hirotani, Akira Matsumura

A novel semiclassical gravity model proposed by Oppenheim et al., that consistently describes interactions between quantum systems and a classical gravitational field, has recently…

Relativistic quantum Otto heat engine using a three-level Unruh-DeWitt detector

Tomoya Hirotani, Kensuke Gallock-Yoshimura

In this study, we explore a relativistic quantum Otto heat engine with a qutrit as the working substance interacting with a quantum scalar field in curved spacetime. Unlike qubits,…

Large violation of Leggett-Garg inequalities with coherent-state projectors for a harmonic oscillator and chiral scalar field

Tomoya Hirotani, Akira Matsumura, Yasusada Nambu +1

We investigate violations of Leggett-Garg inequalities (LGIs) for a harmonic oscillator and a (1+1)-dimensional chiral scalar field with coherent-state projectors, which is equival…
