Magnetoelectric coupling in a ferroelectric/ferromagnetic chain revealed by ferromagnetic resonance
A. Sukhov, P. P. Horley, C. -L. Jia +1
Understanding the multiferroic coupling is one of the key issues in the feld of multiferroics. As shown here theoretically, the ferromagnetic resonance (FMR) renders possible an ac…
Lagrange duality, stability and subdifferentials in vector optimization
Elvira Hernández, Andreas Löhne, Luis Rodríguez-Marín +1
Langrange duality theorems for vector and set optimization problems which are based on an consequent usage of infimum and supremum (in the sense greatest lower and least upper boun…
Time-evolution of excitations in normal Fermi liquids
Y. Pavlyukh, A. Rubio, J. Berakdar
We inspect the initial and the long time evolution of excitations a Fermi liquids by analyzing the time behavior of the electron spectral function. Focusing on the short-time limit…
The Connection between the Number of Realizations for Degree Sequences and Majorization
Annabell Berger
The \emph{graph realization problem} is to find for given nonnegative integers a simple graph (no loops or multiple edges) such that each vertex has degree $a…
Nonlinear anomalous Hall effect and negative magnetoresistance in a system with random Rashba field
V. K. Dugaev, M. Inglot, E. Ya. Sherman +2
We predict two spin-dependent transport phenomena in two-dimensional electron systems, which are induced by spatially fluctuating Rashba spin-orbit interaction. When the electron g…
Theoretical proposal for the dynamical control of the nonlinear optical response frequency
L. Chotorlishvili, A. Sukhov, S. Wimberger +1
We propose theoretically a method for the control of the frequency of the nonlinear optical response of a model nonlinear medium driven by an electric field and suggest an experime…
An Algorithm to Solve Polyhedral Convex Set Optimization Problems
Andreas Löhne, Carola Schrage
An algorithm which computes a solution of a set optimization problem is provided. The graph of the objective map is assumed to be given by finitely many linear inequalities. A solu…
Strategies in crowd and crowd structure
P. Gawronski, K. Malarz, M. J. Krawczyk +6
In an emergency situation, imitation of strategies of neighbours can lead to an order-disorder phase transition, where spatial clusters of pedestrians adopt the same strategy. We a…
Controlling shot noise in double-barrier magnetic tunnel junctions
J. P. Cascales, D. Herranz, F. G. Aliev +6
We demonstrate that shot noise in Fe/MgO/Fe/MgO/Fe double-barrier magnetic tunnel junctions is determined by the relative magnetic configuration of the junction and also by the asy…
Semi-classical approximation for the second harmonic generation in nanoparticles
Y. Pavlyukh, J. Berakdar, W. Hübner
Second harmonic generation by spherical nanoparticles is a non-local optical process that can also be viewed as the result of the non-linear response of the thin interface layer. T…
Scattering function of semiflexible polymer chains under good solvent conditions
Hsiao-Ping Hsu, Wolfgang Paul, Kurt Binder
Using the pruned-enriched Rosenbluth Monte Carlo algorithm, the scattering functions of semiflexible macromolecules in dilute solution under good solvent conditions are estimated b…
On an endomorphism ring of local cohomology
Majid Eghbali, Peter Schenzel
Let be an ideal of a local ring with For the local cohomology module it is a well-known fact that it vanishes for and is an A…
Lagrange Duality in Set Optimization
Andreas H. Hamel, Andreas Löhne
Based on the complete-lattice approach, a new Lagrangian duality theory for set-valued optimization problems is presented. In contrast to previous approaches, set-valued versions f…
Negative differential magneto-resistance in ferromagnetic wires with domain walls
Nicholas Sedlmayr, Jamal Berakdar
A domain wall in a ferromagnetic one-dimensional nanowire experiences current induced motion due to its coupling with the conduction electrons. When the current is not sufficient t…

Martin Meyries, Mark Veraar
In this paper we characterize the trace spaces of a class of weighted function spaces of intersection type with mixed regularities. To a large extent we can overcome the difficulty…

Inspired by the models of A. Rebei and G. J. Parker and A. Rebei et. al., we study a physical model which describes the behaviour of magnetic moments in a ferromagnet. The magnetic…
Attosecond tracking of light absorption and refraction in fullerenes
A. S. Moskalenko, Y. Pavlyukh, J. Berakdar
The collective response of matter is ubiquitous and widely exploited, e.g. in plasmonic, optical and electronic devices. Here we trace on an attosecond time scale the birth of coll…
