Today's Featured Scientist
Dr Bindiya Arora
Assistant Professor
Dept. of Physics, GNDU, Amritsar (India)
During her tenure at GNDU, she has been actively involved in her research and teaching duties. At present, her research group is engaged in understanding the physics behind the use of atomic systems for trapping and cooling of atomic systems, next-generation atomic clocks, quantum computers, cold atom physics and revivals and collapses of quantum systems.
As a part of the research work, a database of atomic properties of monovalent systems has been developed. The research work involves the calculation of magic wavelengths in alkali-metal atoms which facilitates state insensitive optical cooling and trapping and is important for quantum computational schemes, Bose-Einstein condensation, atomic-optical clocks, and many more. She along with her other collaborator from Physical Research Lab, Ahmedabad (India) have proposed a new and effective trapping scheme for neutral atoms using a circularly polarized laser beam. The database has been used for the evaluation of various radiative properties for medium and highly charged ions. These properties have tremendous applications in Astro and plasma physics. The developed database is also used to minimize the uncertainty budget in optical atomic clocks based on Ca+, Sr+, and Ba+ ions, which facilitates the experimental realization of high precision clocks.
Her research group is also involved in the calculation of dispersion and interaction coefficients for interaction among atom-atom, atom-ion, atom-material surfaces, and atom-carbon nanostructures for their further application in ultra-cold atom physics. The research work has been published in international journals and was also presented at various international conferences. At present, her group is involved in the high precision calculation of higher-order shifts in energy levels in the presence of external fields. The cold atom groups around the globe will be benefited from the outcome of this work. Her latest work includes proposing an exceptional optical frequency standard with better short-term and long-term stabilities using the active working principle of optical atomic clocks. The work is being carried out in collaboration with the theoretical group at the Institute Of Physics, China, and the experimental group at Peking University, Beijing, China. Her research work has been recognised by INSA-SCOPUS and she was selected among the top three women scientists by INSA- SCOPUS 2019. One of her recent works includes visualizing the dynamical behaviour of various quantum systems and examining the effect of dissipation on the phenomenon of quantum collapses and revivals. Such visualizations have become increasingly relevant as a pedagogical tool to facilitate the understanding of highly nonclassical and the least intuitive quantum phenomenon. During her stay at GNDU, she has been consistently interacting with the eminent experimentalists in the field of material sciences, which has inculcated her interest in theoretical studies of nanostructures. She along with her experimentalist collaborators from GNDU have started working on the theoretical and experimental study of layered transition metal dichalcogenides (LMTDs) for their application in sensors and solar cells. They plan to use density functional theory (DFT) for electronic-structure calculations and materials modelling at the nanoscale. She also likes to work with various societies and clubs for the promotion of science among the young generation.
