Effects of Inelastic Scattering on Tunneling Time in Generalized Nelson's Quantum Mechanics
Kentaro Imafuku, Ichiro Ohba, Yoshiya Yamanaka
We analyze the effects of inelastic scattering on the tunneling time theoretically, using generalized Nelson's quantum mechanics. This generalization enables us to describe quantum…
Emergence of a Wiener process as a result of the quantum mechanical interaction with a macroscopic medium
Raffaella Blasi, Hiromichi Nakazato, Mikio Namiki +1
We analyze a modified version of the Coleman-Hepp model, that is able to take into account energy-exchange processes between the incoming particle and the linear array made up of $…
Quantum dephasing by chaos
Hiromichi Nakazato, Mikio Namiki, Saverio Pascazio +1
We examine whether the chaotic behavior of classical systems with a limited number of degrees of freedom can produce quantum dephasing, against the conventional idea that dephasing…
Understanding the quantum Zeno effect
Hiromichi Nakazato, Mikio Namiki, Saverio Pascazio +1
The quantum Zeno effect consists in the hindrance of the evolution of a quantum system that is very frequently monitored and found to be in its initial state at every single measur…
