Quantum light depolarization: the phase-space perspective
A. B. Klimov, J. L. Romero, L. L. Sanchez-Soto +2
Quantum light depolarization is handled through a master equation obtained by coupling dispersively the field to a randomly distributed atomic reservoir. This master equation is so…
Entanglement dynamics of two independent qubits in environments with and without memory
B. Bellomo, R. Lo Franco, G. Compagno
A procedure to obtain the dynamics of independent qudits (-level systems) each interacting with its own reservoir, for any arbitrary initial state, is presented. This is the…
Accretion and Outflow-Related X-Rays in T Tauri Stars
M. Guedel, K. Briggs, K. Arzner +22
We report on accretion- and outflow-related X-rays from T Tauri stars, based on results from the "XMM-Newton Extended Survey of the Taurus Molecular Cloud." X-rays potentially form…
The non-random walk of stock prices: The long-term correlation between signs and sizes
Gabriele La Spada, J. Doyne Farmer, Fabrizio Lillo
We investigate the random walk of prices by developing a simple model relating the properties of the signs and absolute values of individual price changes to the diffusion rate (vo…
Estimation of the Repeatedly-Projected Reduced Density Matrix under Decoherence
H. Nakazato, K. Yuasa, B. Militello +1
Decoherence is believed to deteriorate the ability of a purification scheme that is based on the idea of driving a system to a pure state by repeatedly measuring another system in…
Spectral analysis of LMC X-2 with XMM/Newton: unveiling the emission process in the extragalactic Z-source
G. Lavagetto, R. Iaria, A. D'Ai' +2
We present the results of the analysis of an archival observation of LMC X-2 performed with XMM/Newton. The spectra taken by high-precision instruments have never been analyzed bef…
