Specifically, the two tuning nanoscatterers set the resonator at an "exceptional point," a special state of a system at which unusual phenomena may occur. The third nanoscatterer perturbs the system, ...
Let’s say you’re trying to pinpoint when a particular past event occurred, but your best possible estimate puts it only within a span of 10,000 years. Now imagine if something could shrink that window...
A team of researchers, led by a group at the University of California, Riverside, have demonstrated for the first time the transmission of electrical signals through insulators in a sandwich-like stru...

In May 2011, when the U.S. Army Corps of Engineers used explosives to breach a levee south of Cairo, Ill., diverting the rising waters of the Mississippi and Ohio rivers to prevent flooding in the tow...
On the better behaved version of the GKZ hypergeometric system
the better behaved version the GKZ hypergeometric system
2010/12/27
We define a version of the generalized hypergeometric system introduced by Gelfand, Kapranov and Zelevinski (GKZ) suited for the case when the underlying lattice is replaced by a finitely generated a...

We show how to improve the molecular dynamics step of Hybrid Monte Carlo, both by tuning the integrator using Poisson brackets measurements and by the use of force gradient integrators. We present res...

Decoherence in Bose-Einstein Condensates: towards Bigger and Better Schroedinger Cats
Decoherence Bose-Einstein Condensates Schroedinger Cats
2010/10/18
We consider a quantum superposition of Bose-Einstein condensates in two immiscible
internal states. A decoherence rate for the resulting Schr¨odinger cat is calculated and
shown to be a significant ...
