Self-organization of ultrasound in viscous fluids
V. J. Sanchez-Morcillo, J. Martinez-Mora, I. Perez-Arjona +2
We report the theoretical and experimental demonstration of pattern formation in acoustics. The system is an acoustic resonator containing a viscous fluid. When the system is drive…
Diffusion stabilizes cavity solitons in bidirectional lasers
Isabel Perez-Arjona, Victor Sanchez-Morcillo, Javier Redondo +2
We study the influence of field diffusion on the spatial localized structures (cavity solitons) recently predicted in bidirectional lasers. We find twofold positive role of the dif…
Derivation of the spatio-temporal model equations for the thermoacoustic resonator
Isabel Perez-Arjona, Victor J. Sanchez-Morcillo, German de Valcarcel
We derive the model equations describing the thermoacoustic resonator, that is, an acoustical resonator containing a viscous medium inside. Previous studies on this system have add…
Cavity solitons in bidirectional lasers
Isabel Perez-Arjona, Victor J. Sanchez-Morcillo, Eugenio Roldan
We show theoretically that a broad area bidirectional laser with slightly different cavity losses for the two counterpropagating fields sustains cavity solitons (CSs). These struct…
Ultrasonic cavity solitons
I. Perez-Arjona, V. J. Sanchez-Morcillo, G. J. de Valcarcel
We report on a new type of localized structure, an ultrasonic cavity soliton, supported by large aspect-ratio acoustic resonators containing viscous media. The spatio-temporal dyna…
Pattern formation in parametric sound generation
Isabel Perez-Arjona, Victor J. Sanchez-Morcillo
Pattern formation of sound is predicted in a driven resonator where subharmonic generation takes place. A model allowing for diffraction of the fields (large-aspect ratio limit) is…
Domain wall dynamics in an optical Kerr cavity
Victor J. Sanchez-Morcillo, Victor Espinosa, Isabel Perez-Arjona +3
An anisotropic (dichroic) optical cavity containing a self-focusing Kerr medium is shown to display a bifurcation between static --Ising-- and moving --Bloch-- domain walls, the so…
Ising-Bloch Transition in Degenerate Optical Parametric Oscillators
Isabel Perez-Arjona, Fernando Silva, German J. de Valcarcel +2
Domain walls in type I degenerate optical parametric oscillators are numerically investigated. Both steady Ising and moving Bloch walls are found, bifurcating one into another thro…
