The generation of nonclassical light states bears a paramount importance in quantum optics and is largely relying on the interaction between intense laser pulses and nonlinear media. Recently, electron beams, such as tho...

The methodology developed provides for a systematic way to find an infinite number of the novel stable bright and dark ‘‘soliton islands’’ in a ‘’sea of solitary waves’’ of the non linear Schrödinger equation mo...

The Thomas–Reiche–Kuhn (TRK) sum rule is a fundamental consequence of the position–momentum commutation relation for an atomic electron, and it provides an important constraint on the transition matrix elements for...

The aerospace industry is a very unforgiving field, where even the smallest error could have catastrophic consequences. To reduce the risk of disaster, multiple systems are put into place to provide accurate information ...

Manipulation of light-matter interaction is critical in modern physics, especially in the strong coupling regime, where the generated half-light, half-matter bosonic quasiparticles as polaritons are important for fundame...

Optofluidics is a rising technology that combines microfluidics and optics. Its goal is to manipulate light and flowing liquids on the micro/nanoscale and exploiting their interaction in optofluidic chips. The fluid flow...

Kerr-lens mode-locked Ti:sapphire lasers are known to display three coexistent modes of operation: continuous wave, transform limited pulses (P1), and positive chirped pulses (P2). Extreme events (sometimes also called o...

In this study we present the comparison of the performance of two systems to measure intraocular scattering. Measurements were made by using a psychophysical system based on a brightness comparison method that provides a...

This paper presents an analytical formalism that allows for a description of a variety of non linear optical phenomena occurring when an electromagnetic wave propagates through a nematic liquid crystal. First, by using o...

A source of entangled photons based on well-separated laser pump pulses (PDs) with a duration in the nanosecond range may be useful in many applications. Yet, such a source has intrinsic problems arising from the simulta...
