'THERMAL METAMATERIAL’ INNOVATION COULD HELP BRING WASTE-HEAT HARVESTING TECHNOLOGY TO POWER PLANTS, FACTORIES
An international research team has used a "thermal metamaterial" to control the emission of radiation at high temperatures, an advance that could bring devices able to efficiently harvest waste heat from power plants and factories. Roughly 50 to 60 percent of the energy generated in coal and oil...
CONTROLLING HEAT WITH CERAMIC NANOTUBES
New ceramic nanotubes could prolong aircraft engine coatings by controlling high-temperature heat radiation. Idha Valeur reports. In an attempt to increase the lifetime of ceramic coatings used for gas turbines in aircrafts, researchers have developed a new material that can control the engine’s...

Topological optical N-insulators
Quantum gyroelectric effect: Photon spin-1 quantization in continuum topological bosonic phases Topological phases of matter arise in distinct fermionic and bosonic flavors. The fundamental differences between them are encapsulated in their rotational symmetries—the spin. Although spin quantization...
Dipole-dipole interactions in nanophotonics
Single photon pulse induced transient entanglement force We show that a single photon pulse incident on two interacting two-level atoms induces a transient entanglement force between them. After absorption of a multi-mode Fock state pulse, the time-dependent atomic interaction mediated by the vacuum...
Vacuum Fluctuations & Casimir forces
Singular evanescent wave resonances in moving media Resonators fold the path of light by reflections leading to a phase balance and thus constructive addition of propagating waves. However, amplitude decrease of these waves due to incomplete reflection or material absorption leads to a finite...
Electron Energy Loss Spectroscopy
Strong nanoscale light–matter interaction is often accompanied by ultraconfined photonic modes and large momentum polaritons existing far beyond the light cone. A direct probe of such phenomena is difficult due to the momentum mismatch of these modes with free space light, however, fast electron...
Machine Perception
Machine perception uses advanced sensors to collect information about the surrounding scene for situational awareness. State-of-the-art machine perception using active sonar, radar and LiDAR to enhance camera vision 9 faces difficulties when the number of intelligent agents scales up. Exploiting...
