Enhancement of Zener tunneling rate via electron-hole attraction within a time-dependent quasi-Hartree-Fock method
Yasushi Shinohara, Haruki Sanada, Katsuya Oguri
The tunneling process, a prototypical phenomenon of nonperturbative dynamics, is a natural consequence of photocarrier generation in materials irradiated by a strong laser. Common…
Observation of Acoustically Induced Dressed States of Rare-Earth Ions
Ryuichi Ohta, Gregoire Lelu, Xuejun Xu +9
Acoustically induced dressed states of long-lived erbium ions in a crystal are demonstrated. These states are formed by rapid modulation of two-level systems via strain induced by…
1-MHz operation of 1.7-cycle multiple plate compression at 35-W average output power
Takuya Okamoto, Yoji Kunihashi, Yasushi Shinohara +3
We generated 1.7-cycle and 35-J pulses at a 1-MHz repetition rate by using two-stage multiple plate continuum compression of Yb-laser pulses with 80-W average input power. By ad…
Flying electron spin control gates
Paul L. J. Helgers, James A. H. Stotz, Haruki Sanada +3
The control of "flying" (or moving) spin qubits is an important functionality for the manipulation and exchange of quantum information between remote locations on a chip. Typically…
Cavity magnomechanics with surface acoustic waves
D. Hatanaka, M. Asano, H. Okamoto +3
Magnons, namely spin waves, are collective spin excitations in ferromagnets, and their control through coupling with other excitations is a key technology for future hybrid spintro…
Towards phonon routing: Controlling propagating acoustic waves in the quantum regime
M K Ekström, T Aref, A Ask +5
We explore routing of propagating phonons in analogy with previous experiments on photons. Surface acoustic waves (SAWs) in the microwave regime are scattered by a superconducting…
Sidewall quantum wires on GaAs(001) substrates
Paul L. J. Helgers, Haruki Sanada, Yoji Kunihashi +2
We study the structural, optical, and transport properties of sidewall quantum wires on GaAs(001) substrates. The QWRs are grown by molecular beam epitaxy (MBE) on GaAs(001) substr…
