Graduate student Farid Kahlor gave a talk on "Quantum Sensing of Photonic Spin Density Using a Single Spin Qubit" at the 2021 OSA Imaging and Applied Optics Congress. You can read more about it in this Arxiv version of the paper.

Researchers have detected the rolling movement of a nano-acoustic wave predicted by the famous physicist and Nobel prize winner Lord Rayleigh in 1885. This phenomenon can find applications in acoustic quantum technologies or in so-called “phononic” components, which are used to control the...

Congratulations to Mohammad Ali Javidian on the acceptance of an abstract about Quantum Causal Inference: An Entropic Approach which was presented virtually at the Causal Inference Workshop at UAI on July 30th, 2021

Congratulations to Farhad on his paper “Ultrafast electron cycloids driven by the transverse spin of a surface acoustic wave” which was published in Science Advances. Check out the publication in Science Advances .

Nitrogen-vacancy (NV) centers in diamond have emerged as promising room-temperature quantum sensors for probing condensed matter phenomena ranging from spin liquids, two-dimensional (2D) magnetic materials, and magnons to hydrodynamic flow of current. Here we propose and demonstrate that the...

Congratulations to Ashwin for winning the Emil Wolf best student paper prize at Frontiers of Optics 2021. His research is related to dipole-dipole interactions in nanophotonics. These interactions occur between atoms or molecules and are responsible for phenomena like Van Der Waals forces - think...

Professor Zubin Jacob has been elected as one of the Optica (formerly OSA) 2022 Fellows Class. He is among 106 new fellows from 24 countries who were selected based on several factors, including distinguished contributions to education, research, engineering, business, and serving the community...

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.

Congratulations to Yifan and Chinmay on their paper, “Broadband circularly polarized thermal radiation from magnetic Weyl semimetals” being published in Optical Materials Express. The paper demonstrates that a planar slab made of magnetic Weyl semimetal (a class of topological materials) can emit...
