Semiclassical representation of the Hubbard model
Yuki Yamasaki, Hidemaro Suwa, Cristian D. Batista +1
By revisiting the path-integral formulation of the Hubbard model, we propose a theoretical approach based on a semiclassical approximation employing an unconventional coherent-stat…
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…
