Prof. Ram Kuntal Hazra
(Professor)
Prof. Ram Kuntal Hazra is currently serving the Department of Chemistry as a professor. His association with the department dates back to April 2010.
He obtained his Master’s degree in Chemistry from IIT Roorkee, Uttarakhand. He qualified the National Eligibility Test (NET, UGC-CSIR) in December 2000 and in June 2003, out of which in the former case he secured a position within top 20%, resulting in himself getting called for Dr. Shyama Prasad Mukherjee Fellowship. He qualified the Graduate Aptitude Test of Engineering (IIT Kanpur, February 2001 with rank 44).
After having a brief stint as a scholar with the Tata Institute of Fundamental Research, Mumbai, Prof. Hazra worked for his doctoral degree at the Department of Physical Chemistry, Indian Association for the Cultivation of Science (IACS), under the supervision of Prof. Shankar Prasad Bhattacharyya and was awarded the degree by the Jadavpur University, Kolkata. He did his research work as a theoretical chemist in the realm of optical responses, controlled excitation, and impact of impurities on single 2D quantum dots.
Prof. Hazra joined the theoretical/computational group of Professor Dr. Michelle Parrinello in Swiss Federal Institute of Technology, ETH-Zurich (2008-2009). He was awarded Dr. D. S. Kothari Post-Doctoral Fellowship under the mentorship of Professor Kamal Bhattacharya at the Department of Chemistry, University of Calcutta.
His research group mainly focusses on development of many-body interactions in lateral (electrical) and transverse (magnetic) confinements by Coulomb’s Green function and Neumann’s expansion in generic coordinates. Condensed matter physics generally deals with electron-electron, electron-hole, and electron-phonon interactions. On the other hand, chemistry deals with atoms, molecules and ions that can be imagined as many-centre many-electron structures where the two-centre one-electron and the two-centre two-electron systems act as building blocks. Therefore, they are currently trying to develop feasible analytical quantum mechanical methods for moderately large systems, e.g., small microclusters.
The current research interest of Prof. Hazra hovers over a wide range of topics encompassing frontline areas of quantum and statistical mechanics involving quite a phenomenal mathematical intervention.
Prof. Hazra has been actively guiding research for the degree of PhD and has several publications in national and international journals of repute.
