Negativity volume of the generalized Wigner function in gravitating hybrid system
Daisuke Miki, Akira Matsumura, Kazuhiro Yamamoto
We evaluate the gravity-induced negativity volume of the generalized Wigner function in a hybrid system consisting of a particle in a two-localized superposition state and an oscil…
Violation of the two-time Leggett-Garg inequalities for a coarse-grained quantum field
Masaki Tani, Kosei Hatakeyama, Daisuke Miki +2
We investigate the violation of the Leggett-Garg inequalities for a quantum field, focusing on the two-time quasi-probability distribution function of the dichotomic variable with…
Violation of the two-time Leggett-Garg inequalities for a harmonic oscillator
Kosei Hatakeyama, Daisuke Miki, Masaki Tani +5
We investigate the violation of the Leggett-Garg inequalities for a harmonic oscillator in various quantum states. We focus on the two-time quasi-probability distribution function…
