A Cooper pair light emitting diode
H. Sasakura, S. Kuramitsu, Y. Hayashi +7
We demonstrate Cooper-pair's drastic enhancement effect on band-to-band radiative recombination in a semiconductor. Electron Cooper pairs injected from a superconducting electrode…
Sliding conduction by the quasi one-dimensional charge-ordered state in SrCaCuO
A. Maeda, R. Inoue, H. Kitano +3
Nonlinear conduction (NLC) of the two-leg spin ladder, SrCaCuO, was investigated for the =0, 1 and 12 materials . Although insulating materials (=0…
Microwave and millimeter wave spectroscopy in the slightly hole-doped ladders of SrCuO
H. Kitano, R. Inoue, T. Hanaguri +6
We have measured the temperature- and frequency dependence of the microwave and millimeter wave conductivity along both the ladder (c-axis) and the leg (a-axis) direct…
STM/STS study on large pseudogap and nodal superconducting gap in Bi2201(La) and Bi2212
T. Kurosawa, T. Yoneyama, Y. Takano +8
In the present work, scanning tunneling microscopy/spectroscopy (STM/STS) measurements were carried out on underdoped and $\rm Bi_2Sr_2…
Measuring Qutrit-Qutrit Entanglement of Orbital Angular Momentum States of an Atomic Ensemble and a Photon
R. Inoue, T. Yonehara, Y. Miyamoto +2
Three-dimensional entanglement of orbital angular momentum states of an atomic qutrit and a single photon qutrit has been observed. Their full state was reconstructed using quantum…
Entanglement of orbital angular momentum states between an ensemble of cold atoms and a photon
R. Inoue, N. Kanai, T. Yonehara +3
Recently, atomic ensemble and single photons were successfully entangled by using collective enhancement [D. N. Matsukevich, \textit{et al.}, Phys. Rev. Lett. \textbf{95}, 040405(2…
