Latest Paper in Physical Review B
We are delighted to share our recent work on "First-principles study of large gyrotropy in MnBi for infrared thermal photonics", published in Physical Review B. It talks about how nonreciprocal gyrotropic materials have attracted significant interest recently in material physics, nanophotonics, and...
LIGHTING A FIRE WITH VACUUM FRICTION
ONE OF THE SURPRISES OF QUANTUM MECHANICS IS ZERO POINT FLUCTUATIONS WHICH PERVADE BOTH VACUUM AND MATTER. Far from just theoretical interest, practical consequences exist at the nanoscale when these fluctuations cause forces that attract or repel macroscopic bodies. They are also manifested at the...
IN HIGH TEMPERATURES, A NEW CLASS OF CERAMICS CONTROLS HEAT RADIATION
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...
EXPLOITING LOSS
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...
Latest paper in Physical Review Applied
Our recent work on 'Limits to Quantum Gate Fidelity from Near-Field Thermal and Vacuum Fluctuations' has been published in Physical Review Applied. We develop a framework to analyze and engineer near-field thermal and vacuum fluctuations in the quantum computing hardware for achieving high-fidelity...
Light-Matter Interactions in Zerovalent Metal-Intercalated MoS2 by Prof. Ashwin Ramasubramaniam
In this talk, Prof. Ashwin Ramasubramaniam spoke about the ways in which the intercalation of layered compounds is a promising route for the scalable synthesis of 2D heterostructures with novel emergent optoelectronic properties. It investigates, via first-principles calculations, the intercalation...
