Biographic Sketch:
Dr. R. Arun, Assistant Professor of Physics, has been working at the Central University of Tamilnadu since 2013. He received his Ph.D. in theoretical Quantum Optics from Physical Research Laboratory, Ahmedabad. After completing his Ph.D., he worked as Postdoctoral Researcher at the Weizmann Institute of Science, Israel, from 2004 -2007. He also had a teaching experience for four years, from 2009-2013, in a private engineering institute (SRM University) in Chennai. He completed his college education in Chennai and received his UG & PG degrees in Physics from the University of Madras. Dr. Arun's research is in the field of theoretical quantum optics, which deals with the interaction between light and matter using quantum mechanical treatments. He has successfully completed the Ph.D. guidance of one student.

Research Highlights :

Dr. R. Arun’s research work focused on quantum dynamics of cold atoms in cavities during his doctoral studies. His recent works have been mainly on studying quantum interference effects in vacuum induced processes in atoms such as spontaneous emission. His contributions are related to the theoretical study of quantum coherence effects on the resonance fluorescence spectrum, superluminal light propagation, and protection of bipartite entanglement. His teaching interest covers a wide range of courses including quantum optics, laser physics, mathematical physics, electromagnetic theory, and quantum mechanics for undergraduate/postgraduate courses.
