Wave breaking in an optical fiber forms dispersive shock waves similar to undular bores in fluids.
The quantum behavior of a neutron bouncing in the gravitational field of the Earth can improve what we know about dark energy and dark matter.
A predicted class of materials called hyperferroelectrics could prove more stable against the depolarizing internal electric fields known to impede ferroelectricity in thin films.
The thermal wake left in air by a bundle of intense laser pulses can act as a channel for sending subsequent laser light over long distances.
New theoretical calculations show that an x-ray free-electron-laser pulse can generate transitions in excited nuclei via an indirect process involving electron capture.
