Unexpectedly large delocalization of the initial excitation in photosynthetic light harvesting
Khadga J. Karki, Junsheng Chen, Atsunori Sakurai +5
Electronic 2D spectroscopy allows nontrivial quantum effects in chemistry and biology to be explored in unprecedented detail. Here, we apply recently developed fluorescence detecte…
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 (…
Generalized lock-in amplifier for precision measurement of high frequency signals
Siyuan Fu, Atsunori Sakurai, Liang Liu +4
We herein formulate the concept of a generalized lock-in amplifier for the precision measurement of high frequency signals based on digital cavities. Accurate measurement of signal…
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…
