A Quantum Damper
Fumihiro Matsui, Hiroaki S. Yamada, Kensuke S. Ikeda
As an application of the classically decayable correlation in a quantum chaos system maintained over an extremely long time-scale (Matsui et al, Europhys.Lett. 113(2016),40008), we…
Relation between irreversibility and entanglement in classically chaotic quantum kicked rotors
Fumihiro Matsui, Hiroaki S. Yamada, Kensuke S. Ikeda
The relation between the degree of entanglement and time scale of time-irreversible behavior is investigated for classically chaotic quantum coupled kicked rotors by comparing the…
Measuring lifetime of correspondence with classical decay of correlation in quantum chaos
Fumihiro Matsui, Hiroaki S. Yamada, Kensuke S. Ikeda
A very weakly coupled linear oscillator is proposed as a detector for observing time-irreversible characteristics of a quantum system, and it is used to measure the lifetime during…
Lifetime of the arrow of time inherent in chaotic eigenstates: case of coupled kicked rotors
Fumihiro Matsui, Hiroaki S. Yamada, Kensuke S. Ikeda
A linear oscillator very weakly coupled with the object quantum system is proposed as a detector measuring the lifetime of irreversibility exhibited by the system, and classically…
Analyticity of Quantum States in One-Dimensional Tight-Binding Model
Hiroaki S. Yamada, Kensuke S. Ikeda
Analytical complexity of quantum wavefunction whose argument is extended into the complex plane provides an important information about the potentiality of manifesting complex quan…
Time-reversal Characteristics of Quantum Normal Diffusion
Hiroaki S. Yamada, Kensuke S. Ikeda
This paper concerns with the time-reversal characteristics of intrinsic normal diffusion in quantum systems. Time-reversible properties are quantified by the time-reversal test; th…
