The holographic principle is one of our best hopes to understand quantum gravity. One of its most prominent examples is the AdS/CFT correspondence, which is also deeply connected to diverse branches of physics, such as condensed matter, quantum information, and optics. During her Fulbright-Nehru Postdoctoral Research fellowship, Dr. Nandi is investigating the interface of quantum theory of gravity and theory of quantum computation. She is working to understand aspects of quantum information theory for non-Lorentzian field theories, in the context of flat-space holography, and also the dynamics of quantum systems.

Kuljeet Kaur Marhas

Dr. Kuljeet Kaur Marhas is a Professor in Planetary Science Division at Physical Research Laboratory. She has been working in three sub divisions of planetary sciences (A) early evolution of Solar system (analyzing early forming solids to understand origin and evolution of Solar System), (B) presolar grains and nucleosynthesis (analyzing presolar/circumstellar grains to understand stellar evolution), (C) differentiated objects (other Solar system bodies like Moon, Mars via meteorites). Dr. Marhas has also been involved in analyzing samples from sample return missions by NASA, JAXA to understand several aspects of solar system formation. Several new scientific (theoretical and experimental) and technical projects have been initiated by her, with her recent/new interest in hydrothermal alterations and volatile transport in/at asteroidal regions.

Dr. Marhas earned her Ph.D. from Physical Research Laboratory (PRL), India, in 2001.

The grand objective of the Dr. Marhas’s Fulbright-Nehru project is to understand nucleosynthesis and temporal evolution of physico-cosmochemical conditions in novae by isotopic studies of sulphur and other elements in presolar nova grains found in meteorites. Specifically, the proposal approach is to analyze a few tens of potential presolar novae grains using C and N isotopic measurements, and subsequently measure their S isotopes to compare them with the latest nova and SN models to unequivocally establish their genealogy and provenance.
