Reversing a granular flow on a vibratory conveyor
R. Grochowski, P. Walzel, M. Rouijaa +2
Experimental results are presented on the transport properties of granular materials on a vibratory conveyor. For circular oscillations of the shaking trough a non-monotonous depen…
Quantum corrected electron holes
A. Luque, H. Schamel, R. Fedele
The theory of electron holes is extended into the quantum regime. The Wigner--Poisson system is solved perturbatively based in lowest order on a weak, standing electron hole. Quant…
Global classical solutions to the spherically symmetric Nordström-Vlasov system
Håkan Andréasson, Simone Calogero, Gerhard Rein
Classical solutions of the spherically symmetric Nordström-Vlasov system are shown to exist globally in time. The main motivation for investigating the mathematical properties of t…
Symmetry and Variation of Hodge Structures
Ingrid C. Bauer, Fabrizio M. E. Catanese
The main problem addressed in the paper is the Torelli problem for n-dimensional varieties of general type, more specifically for varieties with ample canonical bundle. It asks und…
Some new surfaces with
Ingrid C. Bauer, Fabrizio M. E. Catanese
Motivated by a question by D. Mumford : can a computer classify all surfaces with ? we try to show the complexity of the problem. We restrict it to the classification of…
Amplitudes for magnon scattering by vortices in two-dimensional weakly easy-plane ferromagnets
Denis D. Sheka, Ivan A. Yastremsky, Boris A. Ivanov +2
We study magnon modes in the presence of a vortex in a circular easy-plane ferromagnet. The problem of vortex-magnon scattering is investigated for partial modes with different val…
Whirling Hexagons and Defect Chaos in Hexagonal Non-Boussinesq Convection
Yuan-Nan Young, Hermann Riecke, Werner Pesch
We study hexagon patterns in non-Boussinesq convection of a thin rotating layer of water. For realistic parameters and boundary conditions we identify various linear instabilities…
Lévy Statistics for Random Single--Molecule Line Shapes in a Glass
E. Barkai, A. V. Naumov, Yu. G. Vainer +2
We demonstrate that the statistical behavior of random line shapes of single tetra-tert-butylterrylene chromophores embedded in an amorphous polyisobutylene matrix at T=2 K, is des…
Deformations in the large of some complex manifolds, I
Fabrizio Catanese
Main topic of the paper is the determination, for a compact complex manifold , of the class of manifolds which are deformation equivalent to it. If is a complex torus, t…
Fibred K"ahler and quasi-projective Groups
Fabrizio Catanese
We formulate a new theorem giving several necessary and sufficient conditions in order that a surjection of the fundamental group of a compact Kähler manifold onto the fun…
Holomorphic maps onto varieties of non-negative Kodaira dimension
Jun-Muk Hwang, Stefan Kebekus, Thomas Peternell
A classical result in complex geometry says that the automorphism group of a manifold of general type is discrete. It is more generally true that there are only finitely many surje…
From Abel's heritage: transcendental objects in algebraic geometry and their algebrization
Fabrizio Catanese
A mixture of an historical article, and of a survey of recent developments, containing also a couple of new results.
Soliton ratchets out of point-like inhomogeneities
Luis Morales-Molina, Franz G. Mertens, Angel Sanchez
We introduce and study a novel design for a ratchet potential for soliton excitations. The potential is implemented by means of an array of point-like (delta) inhomogeneities in an…
Entanglement and correlation in anisotropic quantum spin systems
Ulrich Glaser, Helmut Büttner, Holger Fehske
Analytical expressions for the entanglement measures concurrence, i-concurrence and 3-tangle in terms of spin correlation functions are derived using general symmetries of the quan…
Internal mode mechanism for collective energy transport in extended systems
Luis Morales-Molina, Niurka R. Quintero, Franz G. Mertens +1
We study directed energy transport in homogeneous nonlinear extended systems in the presence of homogeneous ac forces and dissipation. We show that the mechanism responsible for un…
Towards universal magnetization curves in the superconducting state of RuSr2GdCu2O8
Thomas P. Papageorgiou, Hans F. Braun, Tobias Goerlach +2
Whereas resistivity and ac susceptibility measurements on the magnetic (Tm ~ 130 K) superconductor (Tc,onset ~ 50 K) RuSr2GdCu2O8 (Ru-1212Gd) reported by different research groups…
Dynamics of cholesteric structures in an electric field
O. S. Tarasov, A. P. Krekhov, L. Kramer
Motivated by Lehmann-like rotation phenomena in cholesteric drops we study the transverse drift of two types of cholesteric fingers, which form rotating spirals in thin layers of c…
Nonlinear magnetic field dependence of the conductance in d-wave NIS tunnel junctions
M. Fogelstrom, D. Rainer, J. A. Sauls
The ab-plane NIS-tunnelling conductance in d-wave superconductors shows a zero-bias conductance peak which is predicted to split in a magnetic field. In a pure d-wave superconducto…
Mixed-phase description of colossal magnetoresistive manganites
Alexander Weiße, Jan Loos, Holger Fehske
In view of recent experiments, indicating the spatial coexistence of conducting and insulating regions in the ferromagnetic metallic phase of doped manganites, we propose a refined…
