Effective Equations for the Precession Dynamics of Electron Spins and Electron-Impurity Correlations in Diluted Magnetic Semiconductors
Moritz Cygorek, Vollrath Martin Axt
Starting from a quantum kinetic theory for the spin dynamics in diluted magnetic semiconductors, we derive simplified equations that effectively describe the spin transfer between…
Sedimentation stacking diagram of binary colloidal mixtures and bulk phases in the plane of chemical potentials
Daniel de las Heras, Matthias Schmidt
We give a full account of a recently proposed theory that explicitly relates the bulk phase diagram of a binary colloidal mixture to its phase stacking phenomenology under gravity…
SCULPT: A Schema Language for Tabular Data on the Web
Wim Martens, Frank Neven, Stijn Vansummeren
Inspired by the recent working effort towards a recommendation by the World Wide Web Consortium (W3C) for tabular data and metadata on the Web, we present in this paper a concept f…
The cost of getting local monotonicity
Josep Freixas, Sascha Kurz
Manfred Holler introduced the Public Good index as a proposal to divide a public good among players. In its unnormalized version, i.e., the raw measure, it counts the number of tim…
Large sets of subspace designs
Michael Braun, Michael Kiermaier, Axel Kohnert +1
In this article, three types of joins are introduced for subspaces of a vector space. Decompositions of the Graßmannian into joins are discussed. This framework admits a generaliza…
Optimal control of the convergence time in the Hegselmann--Krause dynamics
Sascha Kurz
We study the optimal control problem of minimizing the convergence time in the discrete Hegselmann--Krause model of opinion dynamics. The underlying model is extended with a set of…
Accretion and differentiation of the terrestrial planets with implications for the compositions of early-formed Solar System bodies and accretion of water
David C. Rubie, Seth A. Jacobson, Alessandro Morbidelli +5
In order to test planetary accretion and differentiation scenarios, we integrated a multistage core-mantle differentiation model with N-body accretion simulations. Impacts between…
Small asteroid system evolution
Seth A. Jacobson
Observations with radar, photometric and direct imaging techniques have discovered that multiple asteroid systems can be divided clearly into a handful of different morphologies, a…
Simultaneous torsion in the Legendre family
Michael Stoll
We improve a result due to Masser and Zannier, who showed that the set i…
The jumping coefficients of non-Q-Gorenstein multiplier ideals
Patrick Graf
Let be a coherent ideal sheaf on a normal complex variety , and let be a real number. De Fernex and Hacon associated a multiplier id…
Role of defects in the onset of wall-induced granular convection
Andrea Fortini, Kai Huang
We investigate the onset of the wall-induced convection in vertically vibrated granular matter by means of experiments and two-dimensional computer simulations. In both simulations…
A Characterization for Decidable Separability by Piecewise Testable Languages
Wojciech Czerwiński, Wim Martens, Lorijn van Rooijen +2
The separability problem for word languages of a class by languages of a class asks, for two given languages and from , whether the…
Deviations from piecewise linearity in the solid-state limit with approximate density functionals
Vojtěch Vlček, Helen R. Eisenberg, Gerd Steinle-Neumann +2
In exact density functional theory (DFT) the total ground-state energy is a series of linear segments between integer electron points, a condition known as "piecewise linearity". D…
Post-main-sequence debris from rotation-induced YORP break-up of small bodies
Dimitri Veras, Seth A. Jacobson, Boris T. Gaensicke
Although discs of dust and gas have been observed orbiting white dwarfs, the origin of this circumstellar matter is uncertain. We hypothesize that the in-situ breakup of small bodi…
On seed island generation and the non-linear self-consistent interaction of the tearing mode with electromagnetic gyro-kinetic turbulence
William Hornsby, Pierluigi Migliano, Rico Buchholz +4
The multi-scale interaction of self-consistently driven magnetic islands with electromagnetic turbulence is studied within the three dimensional, toroidal gyro-kinetic framework. I…
The role of phonons for exciton and biexciton generation in an optically driven quantum dot
D. E. Reiter, T. Kuhn, M. Glassl +1
For many applications of semiconductor quantum dots in quantum technology a well controlled state preparation of the quantum dot states is mandatory. Since quantum dots are embedde…
Flashing flexodomains and electroconvection rolls in a nematic liquid crystal
Peter Salamon, Nandor Eber, Alexei Krekhov +1
Pattern forming instabilities induced by ultralow frequency sinusoidal voltages were studied in a rod-like nematic liquid crystal by microscopic observations and simultaneous elect…
Generalized Burniat type surfaces and Bagnera-de Franchis varieties
Ingrid Bauer, Fabrizio Catanese, Davide Frapporti
In this article we construct three new families of surfaces of general type with p_g = q = 0,K^2 = 6, and seven new families of surfaces of general type with p_g = q = 1, K^2 = 6,…
Phonon-assisted robust and deterministic two-photon biexciton preparation in a quantum dot
S. Bounouar, M. Müller, A. M. Barth +3
We investigate both experimentally and theoretically a simple yet more robust and flexible alternative to Rabi oscillation-type biexciton preparation protocols traditionally used f…
Infinite Geometric Frustration in a Cubic Dipole Cluster
Johannes Schönke, Tobias M. Schneider, Ingo Rehberg
The geometric arrangement of interacting (magnetic) dipoles is a question of fundamental importance in physics, chemistry and engineering. Motivated by recent progress concerning t…
On the radial propagation of turbulence in gyro-kinetic toroidal systems
P. Migliano, R. Buchholz, S. R. Grosshauser +2
In this paper a conservation equation is derived for the radially dependent entropy in toroidal geometry using the local approximation of the gyro-kinetic framework. This equation…
Superadiabatic forces in Brownian many-body dynamics
Andrea Fortini, Daniel de las Heras, Joseph M. Brader +1
Theoretical approaches to nonequilibrium many-body dynamics generally rest upon an adiabatic assumption, whereby the true dynamics is represented as a sequence of equilibrium state…
Bloch's conjecture for Generalized Burniat Type surfaces with
Ingrid Bauer, Davide Frapporti
The aim of this article is to prove Bloch's conjecture, asserting that the group of rational equivalence classes of zero cycles of degree 0 is trivial for surfaces with geometric g…
Movable curves and semistable sheaves
Daniel Greb, Stefan Kebekus, Thomas Peternell
This paper extends a number of known results on slope-semistable sheaves from the classical case to the setting where polarisations are given by movable curve classes. As applicati…
