Phonon-driven ultrafast exciton dissociation at donor-acceptor polymer heterojunctions
Hiroyuki Tamura, John G. S. Ramon, Eric R. Bittner +1
A quantum-dynamical analysis of phonon-driven exciton dissociation at polymer heterojunctions is presented, using a hierarchical electron-phonon model parameterized for three elect…
Exciton dissociation at donor-acceptor polymer heterojunctions: quantum nonadiabatic dynamics and effective-mode analysis
Hiroyuki Tamura, Eric R. Bittner, Irene Burghardt
The quantum-dynamical mechanism of photoinduced subpicosecond exciton dissociation and the concomitant formation of a charge-separated state at a TFB:F8BT polymer heterojunction is…
Non-local Control of the Kondo Effect in a Double Quantum Dot-Quantum Wire Coupled System
S. Sasaki, S. Kang, K. Kitagawa +7
We have performed low-temperature transport measurements on a double quantum dot-quantum wire coupled device and demonstrated non-local control of the Kondo effect in one dot by ma…
Tunable Kondo screening in a quantum dot device
Hiroyuki Tamura, Leonid I. Glazman
We consider electron transport along a single-mode channel which is in contact, via tunnel junctions in its walls, with two quantum dots. Electron tunneling to and from the dots co…
Study of the Sigma-nucleus potential by the (pi^-,K^+) reaction on medium-to-heavy nuclear targets
P. K. Saha, H. Noumi, D. Abe +34
In order to study the Sigma-nucleus optical potential, we measured inclusive (pi^-,K^+) spectra on medium-to-heavy nuclear targets: CH_2, Si, Ni, In and Bi. The CH_2 target was use…
Photoluminescence measurements in Be-delta-doped back-gate induced quantum well
M. Yamaguchi, S. Nomura, D. Sato +3
The photoluminescence (PL) spectra of a two-dimensional electron system induced in a Be-delta-doped GaAs/AlGaAs quantum well (QW) with a back gate are measured. The electron densit…
