Melting of Charge/Orbital Ordered States in NdSrMnO: Temperature and Magnetic Field Dependent Optical Studies
J. H. Jung, H. J. Lee, T. W. Noh +4
We investigated the temperature ( 15 290 K) and the magnetic field ( 0 17 T) dependent optical conductivity spectra of a charge/orbital ordered manganite, N…
Two-Impurity Kondo Effect in Double-Quantum-Dot Systems - Effect of Interdot Kinetic Exchange Coupling
Wataru Izumida, Osamu Sakai
Tunneling conductance through two quantum dots, which are connected in series to left and right leads, is calculated by using the numerical renormalization group method. As the hop…
Reply to ``Comment on `Inverse exciton series in the optical decay of an excitonic molecule' "
Eiji Tokunaga, A. L. Ivanov, Selvakumar V. Nair +1
As a reply to the Comment by I.S. Gorban {\it et al.} (Phys. Rev. B, preceding paper) we summarize our criticism on their claim of the first observation of the series in -Zn…
Quasi-periodic X-ray Flares from the Protostar YLW15
Yohko Tsuboi, Kensuke Imanishi, Katsuji Koyama +2
With ASCA, we have detected three X-ray flares from the Class I protostar YLW15. The flares occurred every ~20 hours and showed an exponential decay with time constant 30-60 ks. Th…
Rotation and X-ray emission from protostars
Thierry Montmerle, Nicolas Grosso, Yohko Tsuboi +1
The ASCA satellite has recently detected variable hard X-ray emission from two Class I protostars in the rho Oph cloud, YLW15 (IRS43) and WL6, with a characteristic time scale ~20h…
Mixed state on a sparsely encoded associative memory model
Tomoyuki Kimoto, Masato Okada
In the present paper, we analyze symmetric mixed states corresponding to the so-called concept formation on a sparsely encoded associative memory model with 0-1 neurons. Three type…
