Realization of symmetric sharing of entanglement in semiconductor microcrystallites coupled by a cavity field
Yu-xi Liu, Adam Miranowicz, Masato Koashi +1
The entanglement of excitonic states in a system of spatially separated semiconductor microcrystallites is investigated. The interaction among the different microcrystallites i…
Few-Electron Quantum Dot Circuit with Integrated Charge Read-Out
J. M. Elzerman, R. Hanson, J. S. Greidanus +5
We report on the realization of a few-electron double quantum dot defined in a two-dimensional electron gas by means of surface gates on top of a GaAs/AlGaAs heterostructure. Two q…
Far-infrared and submillimeter-wave conductivity in electron-doped cuprate La_{2-x}Ce_xCuO_4
A. Pimenov, A. V. Pronin, A. Loidl +2
We performed far-infrared and submillimeter-wave conductivity experiments in the electron-doped cuprate La_{2-x}Ce_xCuO_4 with x = 0.081 (underdoped regime, T_c = 25 K). The onset…
Optimization of evaporative cooling towards a large number of Bose-Einstein condensed atoms
Makoto Yamashita, Masato Koashi, Tetsuya Mukai +3
We study the optimization of evaporative cooling in trapped bosonic atoms on the basis of quantum kinetic theory of a Bose gas. The optimized cooling trajectory for Rb atoms…
Semiconductor-cavity QED in high-Q regimes: Detuning effect
Yu-xi Liu, N. Imoto, S. K. Ozdemir +2
The non-resonant interaction between the high-density excitons in a quantum well and a single mode cavity field is investigated. An analytical expression for the physical spectrum…
In-situ growth of superconducting MgB2 thin films by molecular beam epitaxy
K Ueda, M. Naito
The in-situ growth of superconducting MgB2 thin films was examined from various perspectives. The paper discusses (1) growth temperature, (2) the effect of excess Mg, (3) the effec…
