The structure of dissipative dark matter halos [PDF]

open access: yesJournal of Cosmology and Astroparticle Physics, 2019
Dissipative dark matter self-interactions can affect halo evolution and change its structure. We perform a series of controlled N-body simulations to study impacts of the dissipative interactions on halo properties.

L’intérêt géographique de la logique de S. Lupasco et de la théorie de la néoténie : proposition d’un crible transdisciplinaire pour l’étude de la résilience des géosystèmes urbains

open access: yesCybergeo, 2009
This paper proposes to organize an ongoing geographical field of specific questions on spatial systems around a transdisciplinary cybernetic design. Structured as a developer, it is built on the contradictory antagonistic logic of S.

Structure formation and exotic compact objects in a dissipative dark sector [PDF]

open access: yesJournal of Cosmology and Astroparticle Physics, 2018
We present the complete history of structure formation in a simple dissipative dark-sector model. The model has only two particles: a dark electron, which is a subdominant component of dark matter, and a dark photon. Dark-electron perturbations grow from

High-topological-number magnetic skyrmions and topologically protected dissipative structure [PDF]

open access: yes, 2015
The magnetic skyrmion with the topological number of unity ($Q=1$) is a well-known nanometric swirling spin structure in the nonlinear $\sigma$ model with the Dzyaloshinskii-Moriya interaction.

Structure preserving approximation of dissipative evolution problems [PDF]

open access: yesNumerische Mathematik, 2018
We present a framework for the systematic numerical approximation of nonlinear evolution problems with dissipation. The approach is based on rewriting the problem in a canonical form that complies with the underlying energy-dissipation structure. We show

Complex coupling effects and dissipative structure in nonlinear thermodynamic systems

open access: yesAIP Advances, 2019
It is well known that a dissipative structure can only possibly turn out when the nonlinear system is far away from the equilibrium. In this paper, the instability of steady state in an ideal system with two kinds of irreversible processes has been ...
