High Precision Measurements Using High Frequency Signals

Aohan Jin, Siyuan Fu, Atsunori Sakurai +5

Generalized lock-in amplifiers use digital cavities with Q-factors as high as 5X10^8. In this letter, we show that generalized lock-in amplifiers can be used to analyze microwave (…

Self-excited current oscillations in a resonant tunneling diode described by a model based on the Caldeira-Leggett Hamiltonian

Atsunori Sakurai, Yoshitaka Tanimura

The quantum dissipative dynamics of a tunneling process through double barrier structures is investigated on the basis of non-perturbative and non-Markovian treatment. We employ a…

An approach to quantum transport based on reduced hierarchy equations of motion: Application to a resonant tunneling diode

Atsunori Sakurai, Yoshitaka Tanimura

The quantum dissipative dynamics of a tunneling process through double barrier structures is investigated on the basis of a rigorous treatment for the first time. We employ a Calde…
