Research at Physics in SPSU

The members of the department are actively involved in various theoretical and computational studies in the fields of atomic physics & molecular physics, non-linear dynamics & chaos theory, cryptography with chaos, quasigroups & fractional integral transforms etc, and experimental studies in nanoscience & nanotechnology and nonlinear electronic circuits. Particularly the members have contributed more than ten different private key cryptographic protocols (for images as well as text data) and three pseudo random bit/number generators by exploiting the interesting properties (mixing, ergodicity, sensitivity on initial conditions/system parameters etc.) of various chaotic dynamical systems. Faculty members are also involved in the calculation of triple differential cross sections and spin asymmetries for the electron/positron impact single ionization processes on Inert gases (He, Ne, Ar, Kr and Xe), alkali, alkali earth targets and various ionic targets having relevance to the plasma field. Recently the department has started to work on the study of charge particle interaction with the simple diatomic molecules and molecules of biological interests. The members have also contributed in the experimental work on synthesis and characterization of magnetic materials like Co-Zn-Ferrites. For the characterization of these materials XRD, TEM, VSM measurements and Mossbauer spectroscopic (RT & LT) techniques have been used. The department also offers Ph.D. Programme in the above mentioned research areas. Few recent achievements of faculty members of physics department include JSPS Long Term Fellowship award, APS-IUSSTF Professorship award and ICM2018 Open Arms Travel Grant award.

Prof. Ghanshyam Purohit received JSPS Invitation Fellowship Long-term FY2017 from Japan Society for the Promotion of Science (JSPS) to work on the research project entitled “Calculation of (e, 2e) cross sections for beryllium and its hydride in low temperature plasmas”. He stayed for the period of 10 months (June 2017 – April 2018) at the National Institute for Fusion Science (NIFS), Toki, Japan to work on the JSPS project. Dr. Prithvi Singh visited Missouri University of Science and Technology (MST), Missouri Rolla, USA under the APS-IUSSTF Professorship grant for the duration of four weeks. He delivered lectures on the topics of atomic and molecular physics to the students of MST. Prof. Vinod Patidar will be presenting research paper “A robust chaos based masking and scrambling in fractional Fourier transform domain for image encryption” at the 28th International Congress of Mathematicians to be held in Rio de Janeiro, Brazil during August 2018. For this visit to Brazil, He has been awarded the ICM2018 Open Arms Travel Grant jointly sponsored by the Instituto de Matemática Pura e Aplicada (IMPA), Sociedade Brasileira de Matemática (SBM) and International Mathematical Union (IMU)</P)
