Secure Diversity-Multiplexing Tradeoff of Zero-Forcing Transmit Scheme at Finite-SNR
Zouheir Rezki, Mohamed-Slim Alouini
In this paper, we address the finite Signal-to-Noise Ratio (SNR) Diversity-Multiplexing Tradeoff (DMT) of the Multiple Input Multiple Output (MIMO) wiretap channel, where a Zero-Fo…
Theory of laser-induced demagnetization at high temperatures
A. Manchon, Q. Li, L. Xu +1
Laser-induced demagnetization is theoretically studied by explicitly taking into account interactions among electrons, spins and lattice. Assuming that the demagnetization processe…
Cooperative Beamforming for Dual-Hop Amplify-and-Forward Multi-Antenna Relaying Cellular Networks
Chengwen Xing, Minghua Xia, shaodan Ma +1
In this paper, linear beamforming design for amplify-and-forward relaying cellular networks is considered, in which base station, relay station and mobile terminals are all equippe…
Crossover dynamics of dispersive shocks in Bose-Einstein condensates characterized by two and three-body interactions
M. Crosta, S. Trillo, A. Fratalocchi
We show that the perturbative nonlinearity associated with three-atom interactions, competing with standard two-body repulsive interactions, can change dramatically the evolution o…
Role of electronic correlations in Ga
Zhiyong Zhu, Xuhui Wang, Udo Schwingenschlögl
An extended around mean field (AMF) functional for less localized electrons is developed to quantify the influence of electronic correlations in -Ga. Both the local density…
Bistability and instability of dark-antidark solitons in the cubic-quintic nonlinear Schroedinger equation
M. Crosta, A. Fratalocchi, S. Trillo
We characterize the full family of soliton solutions sitting over a background plane wave and ruled by the cubic-quintic nonlinear Schroedinger equation in the regime where a quint…
