Scientists first to observe plasmons on graphene

With a beam of infrared light, scientists have sent ripples of electrons along the surface of graphene and demonstrated that they can control the length and height of these oscillations, called plasmons, using a simple electrical ...

Nanobelts support manipulation of light

(PhysOrg.com) -- They look like 2-by-4s, but the materials being created in a Rice University lab are more suited to construction with light.

Ripples in the cosmic background

(PhysOrg.com) -- The universe was created 13.73 billion years ago in a blaze of light -- the big bang. We also think that, about 380,000 years later, after matter (mostly hydrogen atoms) had cooled enough for neutral atoms ...

Mathematicians ask: What's in a ripple?

When a fluid or a gas experiences a sudden disturbance, such as a change in pressure or elevation, it often gives rise to a phenomenon known as an undular bore, which consists of a series of rapid oscillations that propagate ...
