A recurrent plot based stochastic nonlinear ray propagation model for underwater signal propagation

Kurths, Juergen; Haiyang, Yao; Haiyan, Wang; Xu, Yong

A stochastic nonlinear ray propagation model is proposed to carry out an exploration of the nonlinear ray theory in underwater signal propagation. The recurrence plot method is proposed to quantify the ray chaos and ...

General scaling of maximum degree of synchronization in noisy complex networks

Traxl, Dominik; Boers, Niklas; Kurths, Jürgen

The effects of white noise and global coupling strength on the maximum degree of synchronization in complex networks are explored. We perform numerical simulations of generic oscillator models with both linear and non-linear ...

Cross-sectional TEM preparation of hybrid inorganic/organic materials systems by ultramicrotomy

Kirmse, H; Oehlschlegel, E; Polzer, F; Blumstengel, S; Sparenberg, M; Henneberger, F

Preparation of hybrid inorganic-organic systems (HIOS) for transmission electron microscopy (TEM) in cross sectional view is the key for understanding the interfacial structure. Strikingly different materials properties ...

The readout and control system of the mid-size telescope prototype of the Cherenkov Telescope Array

Oya, Igor; Anguner, O.; Behera, B.; Birsin, E.; Fuessling, M.; Melkumyan, D.; Schmidt, Torsten; Schwanke, Ullrich; Sternberger, R.; Wegner, P.; Wiesand, S.

The Cherenkov Telescope Array (CTA) is one of the major ground-based astronomy projects being pursued and will be the largest facility for ground-based y-ray observations ever built. CTA will consist of two arrays: one in ...

Towards the quark-gluon plasma Equation of State with dynamical strange and charm quarks

Burger, Florian; Ilgenfritz, Ernst-Michael; Lombardo, Maria Paola; Müller-Preussker, Michael; Trunin, Anton

We present an ongoing project aimed at determining the thermodynamic Equation of State (EoS) of quark-gluon matter from lattice QCD with two generations of dynamical quarks. We employ the Wilson twisted mass implementation ...

The role of the Kramers–Henneberger atom in the higher-order Kerr effect

Richter, Maria; Patchkovskii, Serguei; Morales, Felipe; Smirnova, Olga; Ivanov, Misha

We discuss the connection between strong-field ionization, saturation of the Kerr response and the formation of the Kramers–Henneberger (KH) atom and long-living excitations in intense infrared (IR) external fields. We ...

Weakly nonlinear response of noisy neurons

Voronenko, Sergej O; Lindner, Benjamin

We calculate the instantaneous firing rate of a stochastic integrate-and-fire neuron driven by an arbitrary time-dependent signal up to second order in the signal amplitude. For cosine signals, this weakly nonlinear theory ...

No-Slip Boundary Conditions for Electron Hydrodynamics and the Thermal Casimir Pressure

Hannemann, Mandy; Wegner, Gino; Henkel, Carsten

We derive modified reflection coefficients for electromagnetic waves in the THz and far infrared range. The idea is based on hydrodynamic boundary conditions for metallic conduction electrons. The temperature-dependent ...

Topological susceptibility from Nf = 2 + 1 + 1 lattice QCD at nonzero temperature

Trunin, Anton; Burger, Florian; Ilgenfritz, Ernst-Michael; Lombardo, Maria Paola; Müller-Preussker, Michael

We present results for the topological susceptibility at nonzero temperature obtained from lattice QCD with four dynamical quark flavours. We apply different smoothing methods, including gradient Wilson flow and over-improved ...

Amplitude calibration with the HiSCORE-9 array

Epimakhov, S; Brückner, M; Budnev, N; Bogorodskii, D; Chvalaev, O; Dyachok, A; Gress, O; Horns, D; Ivanova, A; Kiruhin, S; Konstantinov, E; Korosteleva, E; Kunnas, M; Kuzmichev, L; Lubsandorzhiev, B;

HiSCORE is a non-imaging wide-angle Cherenkov array for the detection of extensive air showers induced by ultrahigh energy gamma-rays above 10 TeV and cosmic ray studies above 100 TeV. In October 2013 a 9-station engineering ...
