Shot Noise in Linear Macroscopic Resistors [PDF]

open access: yes, 2004
We report on a direct experimental evidence of shot noise in a linear macroscopic resistor. The origin of the shot noise comes from the fluctuation of the total number of charge carriers inside the resistor associated with their diffusive motion under ...

Fundamentals and applications of spatial dissipative solitons in photonic devices : [Chapter 6] [PDF]

open access: yes, 2009
We review the properties of optical spatial dissipative solitons (SDS). These are stable, self‐localized optical excitations sitting on a uniform, or quasi‐uniform, background in a dissipative environment like a nonlinear optical cavity.

Stability of solitons in PT-symmetric couplers [PDF]

open access: yes, 2011
Families of analytical solutions are found for symmetric and antisymmetric solitons in the dual-core system with the Kerr nonlinearity and PT-balanced gain and loss. The crucial issue is stability of the solitons.

Coupled-mode theory for photonic band-gap inhibition of spatial instabilities [PDF]

open access: yes, 2005
We study the inhibition of pattern formation in nonlinear optical systems using intracavity photonic crystals. We consider mean-field models for singly and doubly degenerate optical parametric oscillators.

Subcritical patterns and dissipative solitons due to intracavity photonic crystals [PDF]

open access: yes, 2007
Manipulation of the bifurcation structure of nonlinear optical systems via intracavity photonic crystals is demonstrated. In particular, subcritical regions between spatially periodic states are stabilized by modulations of the material's refractive ...

Elementary Excitations of a Bose-Einstein Condensate in an Effective Magnetic Field [PDF]

open access: yes, 2007
We calculate the low energy elementary excitations of a Bose-Einstein Condensate in an effective magnetic field. The field is created by the interplay between light beams carrying orbital angular momentum and the trapped atoms. We examine the role of the
