Supersymmetric rotating black hole spacetime tested by geodesics
Valeria Diemer, Jutta Kunz
We present the complete analytical solution of the geodesics equations in the supersymmetric BMPV spacetime \cite{Breckenridge:1996is}. We study systematically the properties of ma…
Hairy Wormholes and Bartnik-McKinnon Solutions
Olga Hauser, Rustam Ibadov, Burkhard Kleihaus +1
We consider Lorentzian wormholes supported by a phantom field and threaded by non-trivial Yang-Mills fields, which may be regarded as hair on the Ellis wormhole. Like the Bartnik-M…
Rotating Boson Stars in Einstein-Gauss-Bonnet gravity
Yves Brihaye, Jürgen Riedel
A self-interacting SU(2)-doublet of complex scalar fields, minimally coupled to Einstein-Gauss-Bonnet gravity is considered in five space-time dimensions. The classical equations a…
Modeling the functional network of primary intercellular Ca wave propagation in astrocytes and its application to study drug effects
Marcelo Pires, Frank Raischel, Sandra Vaz +3
We introduce a simple procedure of multivariate signal analysis to uncover the functional connectivity among cells composing a living tissue and describe how to apply it for extrac…
Extreme events in excitable systems and mechanisms of their generation
Gerrit Ansmann, Rajat Karnatak, Klaus Lehnertz +1
We study deterministic systems, composed of excitable units of FitzHugh-Nagumo type, that are capable of self-generating and self-terminating strong deviations from their regular d…
Rogue Waves In Nonlinear Schrödinger Models with Variable Coefficients: Application to Bose-Einstein Condensates
J. S. He, E. G. Charalampidis, P. G. Kevrekidis +1
We explore the form of rogue wave solutions in a select set of case examples of nonlinear Schrödinger equations with variable coefficients. We focus on systems with constant disper…
Properties of rotating Einstein-Maxwell-Dilaton black holes in odd dimensions
Jose Luis Blazquez-Salcedo, Jutta Kunz, Francisco Navarro-Lerida
We investigate rotating Einstein-Maxwell-Dilaton (EMd) black holes in odd dimensions. Focusing on black holes with equal-magnitude angular momenta, we determine the domain of exist…
The Gregory-Laflamme instability and non-uniform generalizations of NUT strings
Burkhard Kleihaus, Jutta Kunz, Eugen Radu
We explore via linearized perturbation theory the Gregory-Laflamme instability of the NUT string (i.e the D=4 Lorentzian NUT solution uplifted to five dimensions). Our results indi…
Bright soliton quantum superpositions: signatures of high- and low-fidelity states
Bettina Gertjerenken
Scattering quantum bright solitons off barriers has been predicted to lead to nonlocal quantum superpositions, in particular the NOON-state. The focus of this paper lies on signatu…
Large enhancement of Forster resonance energy transfer on graphene platforms
Svend-Age Biehs, Girish S. Agarwal
In the view of the applications of Forster resonant energy transfer (FRET) in biological systems which especially require FRET in the inrared region we investigate the great advant…
Aircraft Landing Problem: Efficient Algorithm for a Given Landing Sequence
Abhishek Awasthi, Oliver Kramer, Jörg Lässig
In this paper, we investigate a special case of the static aircraft landing problem (ALP) with the objective to optimize landing sequences and landing times for a set of air planes…
Spinning gauged boson stars in anti-de Sitter spacetime
Olga Kichakova, Jutta Kunz, Eugen Radu
We study axially symmetric solutions of the Einstein-Maxwell-Klein-Gordon equations describing spinning gauged boson stars in a 3+1 dimensional asymptotically AdS spacetime. These…
Compact (A)dS Boson Stars and Shells
Betti Hartmann, Burkhard Kleihaus, Jutta Kunz +1
We present compact Q-balls in an (Anti-)de Sitter background in D dimensions, obtained with a V-shaped potential of the scalar field. Beyond critical values of the cosmological con…
Isorotating Baby Skyrmions
A. Halavanau, Yakov Shnir
We discuss how internal rotation with fixed angular frequency can affect the solitons in the baby Skyrme model in which the global O(3) symmetry is broken to the SO(2). Two particu…

Wilke Trei
This paper describes several new improvements of modular arithmetic and how to exploit them in order to gain more efficient implementations of commonly used algorithms, especially…
Gauss-Bonnet boson stars
Betti Hartmann, Juergen Riedel, Raluca Suciu
We construct boson stars in (4+1)-dimensional Gauss-Bonnet gravity. We study the properties of the solutions in dependence on the coupling constants and investigate these in detail…
Near-field thermal transistor
Philippe Ben-Abdallah, Svend-Age Biehs
Using a block of three separated solid elements, a thermal source and drain together with a gate made of an insulator-metal transition material exchanging near-field thermal radiat…
A counterexample to a theorem of Bremermann on Shilov boundaries
Marek Jarnicki, Peter Pflug
We give a counterexample to the following theorem of Bremermann on Shilov boundaries: if is a bounded domain in having a univalent envelope of holomorphy, say $\w…
Black Holes in Higher Dimensions (Black Strings and Black Rings)
Jutta Kunz
The main focus of this session was the presentation of new higher-dimensional black hole solutions, including black rings, black strings, and multi black holes, and the study of th…
Rotating Wormholes in Five Dimensions
Vladimir Dzhunushaliev, Vladimir Folomeev, Burkhard Kleihaus +2
We consider rotating Lorentzian wormholes with a phantom field in five dimensions. These wormhole solutions possess equal angular momenta and thus represent cohomogeneity-1 configu…
Angular momentum-area proportionality of extremal charged black holes in odd dimensions
Jose Luis Blazquez-Salcedo, Jutta Kunz, Francisco Navarro-Lerida
Extremal rotating black holes in Einstein-Maxwell theory feature two branches. On the branch emerging from the Myers-Perry solutions their angular momentum is proportional to their…
