Pattern orientation in finite domains without boundaries
Lisa Rapp, Fabian Bergmann, Walter Zimmermann
We investigate the orientation of nonlinear stripe patterns in finite domains. Motivated by recent experiments, we introduce a control parameter drop from supercritical inside a do…
Piecewise linearity in the approximation for accurate quasiparticle energy predictions
Matthias Dauth, Fabio Caruso, Stephan Kümmel +1
We identify the deviation from the straight line error (DSLE) -- i.e., the spurious non-linearity of the total energy as a function of fractional particle number -- as the main sou…
The Maximum Scatter TSP on a Regular Grid
Isabella Hoffmann, Sascha Kurz, Jörg Rambau
In the maximum scatter traveling salesman problem the objective is to find a tour that maximizes the shortest distance between any two consecutive nodes. This model can be applied…
Key drivers of EU budget allocation: Does power matter?
Vera Zaporozhets, María García-Valiñas, Sascha Kurz
We examine the determinants of the EU budget expenditures allocation among different countries. In line with earlier literature, we consider two alternative explanations for the EU…
Coset Construction for Subspace Codes
Daniel Heinlein, Sascha Kurz
One of the main problems of the research area of network coding is to compute good lower and upper bounds of the achievable cardinality of so-called subspace codes in $\operatornam…
Constructions and Bounds for Mixed-Dimension Subspace Codes
Thomas Honold, Michael Kiermaier, Sascha Kurz
Codes in finite projective spaces equipped with the subspace distance have been proposed for error control in random linear network coding. The resulting so-called \emph{Main Probl…
Improved upper bounds for partial spreads
Sascha Kurz
A partial -spread in is a collection of -dimensional subspaces with trivial intersection, i.e., each point is covered at most once. So far…
K3 transitions and canonical 3-folds
Stephen Coughlan
We introduce K3 transitions as a geometric approach to studying canonical 3-folds. These transitions link different deformation classes of canonical 3-folds via a combination of bi…
Fossilized condensation lines in the Solar System protoplanetary disk
A. Morbidelli, B. Bitsch, A. Crida +6
The terrestrial planets and the asteroids dominant in the inner asteroid belt are water poor. However, in the protoplanetary disk the temperature should have decreased below water…
Multiple origins of asteroid pairs
Seth A. Jacobson
Rotationally fissioned asteroids produce unbound daughter asteroids that have very similar heliocentric orbits. Backward integration of their current heliocentric orbits provides a…
Particle Conservation in Dynamical Density Functional Theory
Daniel de las Heras, Joseph M. Brader, Andrea Fortini +1
We present the exact adiabatic theory for the dynamics of the inhomogeneous density distribution of a classical fluid. Erroneous particle number fluctuations of dynamical density f…
Non-Kähler complex structures on II
Antonio J. Di Scala, Naohiko Kasuya, Daniele Zuddas
We follow our study of non-Kähler complex structures on that we defined in a previous paper. We prove that these complex surfaces do not admit any smooth complex compactifica…
Quench dynamics of a confined ultracold Fermi gas: Direct visibility of the Goldstone mode in the single-particle excitations
P. Kettmann, S. Hannibal, M. D. Croitoru +2
We present a numerical study of a confined ultracold Fermi gas showing that the Goldstone mode of the BCS gap is directly visible in the dynamics of the single-particle excitations…
Temperature (de)activated patchy colloidal particles
Daniel de las Heras, Margarida M. Telo da Gama
We present a new model of patchy particles in which the interaction sites can be activated or deactivated by varying the temperature of the system. We study the thermodynamics of t…
Spacings - An Example for Universality in Random Matrix Theory
Thomas Kriecherbauer, Kristina Schubert
Universality of local eigenvalue statistics is one of the most striking phenomena of Random Matrix Theory, that also accounts for a lot of the attention that the field has attracte…
On the Robustness of Regularized Pairwise Learning Methods Based on Kernels
Andreas Christmann, Ding-Xuan Zhou
Regularized empirical risk minimization including support vector machines plays an important role in machine learning theory. In this paper regularized pairwise learning (RPL) meth…
Spatiotemporal complexity of electroconvection patterns in nematic liquid crystals
Alexei Krekhov, Bernd Dressel, Werner Pesch +2
We investigate a number of complex patterns driven by the electro-convection instability in a planarly aligned layer of a nematic liquid crystal. They are traced back to various se…
Gravitational collapse and the Vlasov-Poisson system
Gerhard Rein, Lukas Taegert
A self-gravitating homogeneous ball of a fluid with pressure zero where the fluid particles are initially at rest collapses to a point in finite time. We prove that this gravitatio…
Pressure induced crossing of the core-levels in 5d metals
Alexey A. Tal, Mikhail I. Katsnelson, Marcus Ekholm +4
Pressure induced interaction between core electrons, the core level crossing (CLC) transition has been observed in hcp Os at P~400 GPa [L. Dubrovinksy, et al., Nature 525, 226-229…
Formation of the Janus-Epimetheus system through collisions
Lucas Luigi Treffenstädt, Décio C. Mourão, Othon C. Winter
Context: Co-orbital systems are bodies that share the same mean orbit. They can be divided into different families according to the relative mass of the co-orbital partners and the…
The Formation of Striae within Cometary Dust Tails by a Sublimation-Driven YORP-like Effect
Jordan K. Steckloff, Seth A. Jacobson
Sublimating gas molecules scatter off of the surface of an icy body in the same manner as photons. This means that for every photon-driven body force, there should be a sublimation…
Relaxation and coherent oscillations in the spin dynamics of II-VI diluted magnetic quantum wells
Florian Ungar, Moritz Cygorek, Pablo I. Tamborenea +1
We study theoretically the ultrafast spin dynamics of II-VI diluted magnetic quantum wells in the presence of spin-orbit interaction. We extend a recent study where it was shown th…
Non-Markovian Effects in the Spin Transfer Dynamics in Diluted Magnetic Semiconductors due to Excitation in Proximity to the Band Edge
Moritz Cygorek, Vollrath Martin Axt
The non-Markovian effects in the spin dynamics in diluted magnetic semiconductors found in quantum kinetic calculations can be reproduced very well by a much simpler effective sing…
Comparison between a quantum kinetic theory of spin transfer dynamics in Mn doped bulk semiconductors and its Markov limit for non-zero Mn magnetization
Moritz Cygorek, Vollrath Martin Axt
We investigate the transfer between carrier and Mn spins due to the s-d-exchange interaction in a Mn doped bulk semiconductor within a microscopic quantum kinetic theory. We demons…
