In the past decade, the development of artificial materials exhibiting novel optical properties
has become a major scientific endeavor. One particularly interesting system is synthetic soft …

Osmotic conditions play an important role in the cell properties of human red blood cells
(RBCs), which are crucial for the pathological analysis of some blood diseases such as …

We demonstrate a new class of synthetic colloidal suspensions capable of exhibiting
negative polarizabilities, and observe for the first time robust propagation and enhanced …

It is commonly thought that biological media cannot exhibit an appreciable nonlinear optical
response. We demonstrate, for the first time to our knowledge, a tunable optical nonlinearity …

Robust propagation of self-trapped light over distances exceeding 25 diffraction lengths has
been demonstrated for the first time in plasmonic nanosuspensions. This phenomenon …

We experimentally probed the nonlinear optical response of aqueous nano-colloidal
suspensions to provide a test of the theoretical approaches that have been proposed for the …

We demonstrate, theoretically and experimentally, self-trapping of optical beams in
nanoparticle suspensions by virtue of thermophoresis. We use light to control the local …

A nonintegrable model with the super-Kerr nonlinearity is investigated, which describes the
light-matter interactions in a fluidic suspension of colloidal nanoparticles. Existence of the …

We demonstrate two different types of coupled beam propagation dynamics in colloidal gold
nanosuspensions. In the first case, an infrared (IR) probe beam (1064 nm) is guided by a …

We experimentally demonstrate self-trapping of light, as a result of plasmonic resonant
optical nonlinearity, in both aqueous and organic (toluene) suspensions of gold nanorods …
