In this talk, Dr. Chen-Ting Liao introduced the topology of light – the light carrying orbital angular momentum (OAM). The OAM of light can be static, dynamic, or spatiotemporal. Static OAM of light has been known for three decades and has found numerous applications, from optical trapping, and...

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...

Our article from Phys.org, discussing our recent work on "Observation of nonvanishing optical helicity in thermal radiation from symmetry-broken metasurfaces" has been published in Science Advances (2023). Spinning thermal radiation is a unique phenomenon observed in condensed astronomical objects...

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...

Our recent work on ‘Observation of nonvanishing optical helicity in thermal radiation from symmetry-broken metasurfaces’ has been published in Science Advances . We uncover a new method for generating spinning thermal radiation in a controlled & efficient manner using metasurfaces. Spinning thermal...

Quantum causality is an emerging field of study which has the potential to greatly advance our understanding of quantum systems. In this paper, we put forth a theoretical framework for merging quantum information science and causal inference by exploiting entropic principles. For this purpose, we...
