“…The nonlinear wave field in such gases represents a particular case of integrable turbulence, often called soliton turbulence (with the caveat that the latter term has also been used in the context of nonintegrable wave dynamics, see e.g. [19,20]). Generally, soliton gas and soliton turbulence represent two complementary aspects of the same physical object, the natural counterparts of the wave-particle duality of a single soliton.…”

We review the spectral theory of soliton gases in integrable dispersive hydrodynamic systems. We first present a phenomenological approach based on the consideration of phase shifts in pairwise soliton collisions and leading to the kinetic equation for a non-equilibrium soliton gas. Then, a more detailed theory is presented in which soliton gas dynamics are modelled by a thermodynamic type limit of modulated finite-gap spectral solutions of the Korteweg–de Vries and the focusing nonlinear Schrödinger (NLS) equations. For the focusing NLS equation the notions of soliton condensate and breather gas are introduced that are related to the phenomena of spontaneous modulational instability and the rogue wave formation. The integrability properties of the kinetic equation for soliton gas are discussed and some physically relevant solutions are presented and compared with direct numerical simulations of dispersive hydrodynamic systems.

“…The theory of the proximity effect in S/F systems containing magnetic inhomogeneities was comprehensively developed in [1][2][3]; however, many three-dimensional problems are technically difficult. One of these problems is to calculate the critical temperature of the S/F system containing a magnetic vortex or a domain wall [21,22]. In this work, we propose an approximate approach to such problems based on the transition to a new basis by a unitary transformation in the spin space of an itinerant electron.…”

Contact between a superconductor and a chiral ferromagnet containing complex magnetic structures (helical or conical texture, skyrmion, and chiral float) has been considered. The case of a single skyrmion has been studied more thoroughly. The influence of these magnetic inhomogeneities on the critical temperature becomes significant only for nanoscale spin structures (about 100 nm or smaller). Skyrmion lattices and single skyrmions of such sizes have recently been observed in experiments with thin magnetic layers. Within the proximity effect theory in the dirty limit, an approximate approach has been proposed to calculate the critical temperature in these systems. Great influence of nanoscale spin vortices on the critical temperature, in combination with topological stability and a low current density that is necessary for their motion, makes it possible to use these systems as efficient superconducting spin valves.
