We are delighted to share our recent work on “Nonequilibrium Hanbury Brown-Twiss interferometry: Theory and application to binary stars,” published in Physical Review Research. We develop a general formalism of Hanbury Brown and Twiss's experiment for objects at different temperatures. We also apply...

The field of topology or the study of how surfaces behave in different dimensions has profoundly influenced the current understanding of matter. The prime example is the topological insulator, which conducts electricity only on the surface while being completely insulating inside the bulk. Topological insulators behave like a metal, i.e., silver on the surface, but inside, it would behave like glass. These properties are defined using the conductivity or flow of electrons depicting whether there is a highway or a road-block for their motion. One major driver of future applications for topological insulators is in the field of spin-electronic devices since these electrons spin in unison, all aligned with each other while flowing on the surface.

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.

Our recent theory work on the quantum commutation relations for the total angular momentum of light published in Journal of the Optical Society of America B. The total angular momentum of light has received attention for its application in a variety of phenomena such as optical communication...
