Prethermalization in one-dimensional Bose gases: description by a stochastic Ornstein-Uhlenbeck process
Tim Langen, Michael Gring, Maximilian Kuhnert +5
We experimentally study the relaxation dynamics of a coherently split one-dimensional Bose gas using matterwave interference. Measuring the full probability distributions of interf…
Diversity of flux avalanche patterns in superconducting films
J. I. Vestgarden, D. V. Shantsev, Y. M. Galperin +1
The variety of morphologies in flux patterns created by thermomagnetic dendritic avalanches in type-II superconducting films is investigated using numerical simulations. The avalan…
Intrinsic defects in silicon carbide LED as a perspective room temperature single photon source in near infrared
F. Fuchs, V. A. Soltamov, S. Vaeth +4
Generation of single photons has been demonstrated in several systems. However, none of them satisfies all the conditions, e.g. room temperature functionality, telecom wavelength o…
Impact of noise and damage on collective dynamics of scale-free neuronal networks
D. Holstein, A. V. Goltsev, J. F. F. Mendes
We study the role of scale-free structure and noise in collective dynamics of neuronal networks. For this purpose, we simulate and study analytically a cortical circuit model with…
Kuramoto model with frequency-degree correlations on complex networks
B. C. Coutinho, A. V. Goltsev, S. N. Dorogovtsev +1
We study the Kuramoto model on complex networks, in which natural frequencies of phase oscillators and the vertex degrees are correlated. Using the annealed network approximation a…
The Ioffe-Regel criterion and diffusion of vibrations in random lattices
Y. M. Beltukov, V. I. Kozub, D. A. Parshin
We consider diffusion of vibrations in 3d harmonic lattices with strong force-constant disorder. Above some frequency w_IR, corresponding to the Ioffe-Regel crossover, notion of ph…
