The temporal dynamics of large quantum systems perturbed weakly by a single excitation can give rise to unique phenomena at the quantum phase boundaries. Here, we develop a time-dependent model to study the temporal dynamics of a single photon interacting with a defect within a large system of...

The gas turbines powering aircraft engines rely on ceramic coatings that ensure structural stability at high temperatures. But these coatings don’t control heat radiation, limiting the performance of the engine. Researchers at Purdue University have engineered ceramic “nanotubes” that behave as...

Manufacturers frequently use coatings to protect the structural stability of engines or power generators operating at high temperatures. Ceramic shields, however, have not been able to adequately address a critical, performance-limiting factor: heat radiation. Researchers have engineered ceramic...

Metamaterials operating at frequency ranges in which the dielectric permittivity is close to zero have been discussed for use across a wide range of optical applications. Sean Molesky and colleagues from the University of Alberta in Canada, have now proposed methods for engineering thermally excited...
