Laminar-Turbulent Patterns in Shear Flows : Evasion of Tipping, Saddle-Loop Bifurcation and Log scaling of the Turbulent Fraction
Pavan V. Kashyap, Juan F. Marìn, Yohann Duguet +1
We analyze a one-dimensional two-scalar fields reaction advection diffusion model for the globally subcritical transition to turbulence. In this model, the homogeneous turbulent st…
Fluid motion for reducing the bounce of partially filled containers
Klebbert Andrade, Javiera Catalán, Juan F. Marín +4
Certain spatial distributions of water inside partially filled containers can significantly reduce the bounce of the container. In experiments with containers filled to a volume fr…
Drift instabilities in localised Faraday patterns
Juan F. Marín, Rafael Riveros Ávila, Saliya Coulibaly +2
Nature is intrinsically heterogeneous, and remarkable phenomena can only be observed in the presence of intrinsically nonlinear heterogeneities. Spontaneous pattern formation in na…
Generation of gravity waves by pedal-wavemakers
Isis Vivanco, Bruce Cartwright, A. Ledesma Araujo +2
Experimental wave generation in channels is usually achieved through wavemakers (moving paddles) acting on the surface of the water. Although practical for engineering purposes, wa…
Solitons and instantons in vacuum stability: physical phenomena
J. A. Gonzalez, A Bellorin, L E Guerrero +3
In a previous paper [JCAP06, 033 (2018)] we have proved that it is possible to have a stable false vacuum in a potential that is unbounded from below. In this paper we discuss the…
Bubble nucleation around heterogeneities in -field theories
Juan F. Marin
Localised heterogeneities have been recently discovered to act as bubble-nucleation sites in nonlinear field theories. Vacuum decay seeded by black holes is one of the most remarka…
Shape of a recoiling liquid filament
Francesco Paolo Contò, Juan F. Marín, Arnaud Antkowiak +2
We study the capillary retraction of a Newtonian semi-infinite liquid filament through analytical methods. We derive a long-time asymptotic-state expansion for the filament profile…
Stability of bubble-like fluxons in disk-shaped Josephson junctions in the presence of a coaxial dipole current
Alicia G. Castro-Montes, Mónica A. García-Ñustes, Jorge A. González +2
We investigate analytically and numerically the stability of bubble-like fluxons in disk-shaped heterogeneous Josephson junctions. Using ring solitons as a model of bubble fluxons…
Localized Faraday patterns under heterogeneous parametric excitation
Héctor Urra, Juan F. Marín, Milena Páez-Silva +4
Faraday waves are a classic example of a system in which an extended pattern emerges under spatially uniform forcing. Motivated by systems in which uniform excitation is not plausi…
Bubble-like structures generated by activation of internal shape modes in two-dimensional sine-Gordon line solitons
Mónica A. García-Ñustes, Jorge A. González, Juan F. Marín
Nonlinear waves that collide with localized defects exhibit complex behavior. Apart from reflection, transmission, and annihilation of an incident wave, a local inhomogeneity can a…
