Electrically driven magnetic antenna based on multiferroic composites
X. -G. Wang, A. Sukhov, L. Chotorlishvili +3
We suggest and demonstrate via large scale numerical simulations an electrically operated spin- wave inducer based on composite multiferroic junctions. Specifcally, we consider an…
Interplay of nematic and magnetic orders in FeSe under pressure
Daniel D. Scherer, Anthony Jacko, Christoph Friedrich +4
We offer an explanation for the recently observed pressure-induced magnetic state in the iron-chalcogenide FeSe based on \textit{ab initio} estimates for the pressure evolution of…
Bose-Einstein Condensation of Quasi-Particles by Rapid Cooling
M. Schneider, T. Brächer, D. Breitbach +18
The fundamental phenomenon of Bose-Einstein Condensation (BEC) has been observed in different systems of real and quasi-particles. The condensation of real particles is achieved th…
Energy loss spectroscopy of Buckminster C60 with twisted electrons: Influence of orbital angular momentum transfer on plasmon generation
M. Schüler, J. Berakdar
Recent experimental progress in creating and controlling singular electron beams that carry orbital angular momentum allows for new types of local spectroscopies. We theoretically…
Topological insulator in a helicoidal magnetization field
S. Stagraczynski, L. Chotorlishvili, V. K. Dugaev +4
A key feature of topological insulators is the robustness of the electron energy spectrum. At a surface of a topological insulator, Dirac point is protected by the characteristic s…
Resistive Switching and Voltage Induced Modulation of Tunneling Magnetoresistance in Nanosized Perpendicular Organic Spin Valves
Robert Göckeritz, Nico Homonnay, Alexander Müller +2
Nanoscale multifunctional perpendicular organic spin valves have been fabricated. The devices based on an LaSrMnO/Alq/Co trilayer show resistive switching o…
Kinetics of nano-size Ferroelectrics
S. R. Etesami, A. Sukhov, J. Berakdar
We analyze theoretically the finite-temperature polarization dynamic in displacive-type ferroelectrics. In particular we consider the thermally-activated switching time of a single…
Optimization of the ionization time of an atom with tailored laser pulses: a theoretical study
David Kammerlander, Alberto Castro, Miguel A. L. Marques
How fast can a laser pulse ionize an atom? We address this question by considering pulses that carry a fixed time-integrated energy per-area, and finding those that achieve the dou…
Magnon nodal-line semimetals and drumhead surface states in anisotropic pyrochlore ferromagnets
Alexander Mook, Jürgen Henk, Ingrid Mertig
We introduce a new type of topological magnon matter: the magnonic pendant to electronic nodal-line semimetals. Magnon spectra of anisotropic pyrochlore ferromagnets feature twofol…
A unifying framework for fast randomization of ecological networks with fixed (node) degrees
Corrie Jacobien Carstens, Annabell Berger, Giovanni Strona
The switching model is a Markov chain approach to sample graphs with fixed degree sequence uniformly at random. The recently invented Curveball algorithm for bipartite graphs appli…
Thermally induced magnonic spin current, thermomagnonic torques and domain wall dynamics in the presence of Dzyaloshinskii-Moriya interaction
X. -G. Wang, L. Chotorlishvili, G. -H. Guo +4
Thermally activated domain wall (DW) motion in magnetic insulators has been considered theoretically, with a particular focus on the role of Dzyaloshinskii-Moriya Interaction (DMI)…
The role of electron confinement in Pd films for the oscillatory magnetic anisotropy in an adjacent Co layer
Sujit Manna, M. Przybylski, D. Sander +1
We demonstrate the interplay between quantum well states in Pd and the magnetic anisotropy in Pd/Co/Cu(001) by combined scanning tunneling spectroscopy (STS) and magneto optical Ke…
Optical vortices discern attosecond time delay in electron emission from magnetic sublevels

A quantum thermodynamic cycle with a chiral multiferroic working substance such as is presented. Shortcuts to adiabaticity are employed to achieve…
Pulse and quench induced dynamical phase transition in a chiral multiferroic spin chain
M. Azimi, M. Sekania, S. K. Mishra +3
Quantum dynamics of magnetic order in a chiral multiferroic chain is studied. We consider two different scenarios: Ultrashort terahertz (THz) excitations or a sudden electric field…

Marius Erbert, Steffen Rechner, Matthias Müller-Hannemann
A basic task in bioinformatics is the counting of -mers in genome strings. The -mer counting problem is to build a histogram of all substrings of length in a given genome…
Vertex corrections for positive-definite spectral functions of simple metals
