Interaction renormalization and the plasma staircase
Alexander V. Milovanov, Alexander Iomin, Jens Juul Rasmussen
We resolve an existing question concerning dynamical and structural stability of the E {\times} B staircases in magnetically confined fusion plasma. The problem has stirred conside…
Turbulence spreading and anomalous diffusion on combs
Alexander V. Milovanov, Alexander Iomin, Jens Juul Rasmussen
This paper presents a simple model for such processes as chaos spreading or turbulence spillover into stable regions. In this simple model the essential transport occurs via inelas…
Turbulence spreading by the resonant wave-wave interactions: A fractional kinetics approach
Alexander V. Milovanov, Jens Juul Rasmussen
This paper is concerned with the processes of spatial propagation and penetration of turbulence from the regions where it is locally excited into initially laminar regions. The phe…
A mixed SOC-turbulence model for nonlocal transport and Levy-fractional Fokker-Planck equation
Alexander V. Milovanov, Jens Juul Rasmussen
The phenomena of nonlocal transport in magnetically confined plasma are theoretically analyzed. A hybrid model is proposed, which brings together the notion of inverse energy casca…
A mixed SOC-turbulence model for nonlocal transport and space-fractional Fokker-Planck equation
Alexander V. Milovanov, Jens Juul Rasmussen
The phenomena of nonlocal transport in magnetically confined plasma are theoretically analyzed. A hybrid model is proposed, which brings together the notion of inverse energy casca…
Modulational instability, solitons and beam propagation in spatially nonlocal nonlinear media
W. Krolikowski, O. Bang, N. I. Nikolov +4
We present an overview of recent advances in the understanding of optical beams in nonlinear media with a spatially nonlocal nonlinear response. We discuss the impact of nonlocalit…
Fracton pairing mechanism for "strange" superconductors: Self-assembling organic polymers and copper-oxide compounds
Alexander V. Milovanov, Jens J. Rasmussen
Self-assembling organic polymers and copper-oxide compounds are two classes of "strange" superconductors, whose challenging behavior does not comply with the traditional picture of…
Modulational instability in nonlocal nonlinear Kerr media
Wieslaw Krolikowski, Ole Bang, Jens Juul Rasmuss +1
We study modulational instability (MI) of plane waves in nonlocal nonlinear Kerr media. For a focusing nonlinearity we show that, although the nonlocality tends to suppress MI, it…
Finite time singularities in a class of hydrodynamic models
V. P. Ruban, D. I. Podolsky, J. J. Rasmussen
Models of inviscid incompressible fluid are considered, with the kinetic energy (i.e., the Lagrangian functional) taking the form in 3…
