Third-order effect in magnetic small-angle neutron scattering by a spatially inhomogeneous medium
Konstantin L. Metlov, Andreas Michels
Magnetic small-angle neutron scattering (SANS) is a powerful tool for investigating nonuniform magnetization structures inside magnetic materials. Here, considering a ferromagnetic…
Static correlation and electron localization in molecular dimers from the self-consistent RPA and GW approximation
Maria Hellgren, Fabio Caruso, Daniel R. Rohr +4
We investigate static correlation and delocalization errors in the self-consistent GW and random-phase approximation (RPA) by studying molecular dissociation of the H_2 and LiH mol…
r-Matrices, triangular L-bialgebras, and quantum groups
Denis Bashkirov, Alexander A. Voronov
A homotopy analogue of the notion of a triangular Lie bialgebra is proposed with a goal of extending the basic notions of theory of quantum groups to the context of homotopy algebr…
Joint signature of two or more systems with applications to multistate systems made up of two-state components
Jean-Luc Marichal, Pierre Mathonet, Jorge Navarro +1
The structure signature of a system made up of components having continuous and i.i.d. lifetimes was defined in the eighties by Samaniego as the -tuple whose -th coordina…
Stochastic thermodynamics of rapidly driven systems
Gregory Bulnes Cuetara, Andreas Engel, Massimiliano Esposito
We present the stochastic thermodynamics analysis of an open quantum system weakly coupled to multiple reservoirs and driven by a rapidly oscillating external field. The analysis i…
Joint Beamforming Optimization and Power Control for Full-Duplex MIMO Two-way Relay Channel
Gan Zheng
In this paper we explore the use of full-duplex radio to improve the spectrum efficiency in a two-way relay channel where two sources exchange information through an multi-antenna…
