Mode-locking transitions in nano-structured weakly disordered lasers
L. Angelani, C. Conti, L. Prignano +2
We report on a statistical approach to mode-locking transitions of nano-structured laser cavities characterized by an enhanced density of states. We show that the equations for the…
Liquid-like behavior of supercritical fluids
Federico Gorelli, Mario Santoro, Tullio Scopigno +2
The high frequency dynamics of fluid oxygen have been investigated by Inelastic X-ray Scattering. In spite of the markedly supercritical conditions (, )…
Aging of the Nonlinear Optical Susceptibility of colloidal solutions
Neda Ghofraniha, Claudio Conti, Giancarlo Ruocco
Using Z-scan and dynamic light scattering measurements we investigate the nonlinear optics response of a colloidal solution undergoing dynamics slowing down with age. We study the…
Laser beam filamentation in fractal aggregates
Claudio Conti, Neda Ghofraniha, Giancarlo Ruocco +1
We investigate filamentation of a cw laser beam in soft matter such as colloidal suspensions and fractal gels. The process, driven by electrostriction, is strongly affected by mate…
Aging after shear rejuvenation in a soft glassy colloidal suspension: evidence for two different regimes
F. Ianni, R. Di Leonardo, S. Gentilini +1
The aging dynamics after shear rejuvenation in a glassy, charged clay suspension have been investigated through dynamic light scattering (DLS). Two different aging regimes are obse…
Light diffusion and localization in 3D nonlinear disordered media
Claudio Conti, Luca Angelani, Giancarlo Ruocco
Using a 3D Finite-Difference Time-Domain parallel code, we report on the linear and nonlinear propagation of light pulses in a disordered assembly of scatterers, whose spatial dist…
