Research Achievements:

 

• The standard model for chemical reactions in solution would be a particle executing one-dimensional random walk on a harmonic potential, in presence of a point sink, located at an arbitrary position. Very recently an exact time domain solution to this model was proposed by us. This has been an unsolved problem for long time  and is of considerable importance as a model for chemical reaction in solution.

• Two sate model for diffusion-reaction system deals with one dimensional random walk on two  potential wells in presence of coupling between them. Exact Laplace domain solution of this model for point-like coupling between two potentials was proposed by us. This is an interesting & very important work in this field [A. Chakraborty, J. Chem. Phys. 139, 094101 (2013)]. Very recently we have proposed  an exact time domain solution of this same model, which was so far considered to be analytically intractable.



 Teaching Achievements:

 

• More than 1150 lectures are given to ~1500 students of different areas of sciences & engineering with average TCF 4.4/5.0. Total 35 courses were offered, these includes theory courses, Laboratory courses as well as project-based courses.
• Established B. Tech. Chemsitry Laboratory in 2010, this was the first fully functional teaching laboratory in IIT Mandi.

Mentoring of Students:

 

Mentored a large number of students (Chemistry, Physics, Biology, Mathematics & Engineering), at various levels and most of them have continued in research.

1. Number of students at Doctoral level: 8 (one has graduated, one has submitted thesis & three more will be submiiting thesis soon).
2. Total 23 students at the Masters level (thesis). Almost all have continued to do their Ph.D. in theoretical work in well reputed places (IIT/IISc.) in India and abroad.
   
3. Total 56 students at the Bachelor & Master's level for internship or project work. Again most have continued to do research.
4. One Ph.D. student will be joining as post-doc under the legendary professor R. D. Levine in the Hebrew University of Jerusalem.
   

 

 

 

Science Education:

 

Dr. Chakraborty is very active in promoting science Education. This includes giving talks at various levels to students, and writing articles at a level that can be understood by under graduate and post graduate students. Theoretical chemistry is not a very popular subject in Himachal Pradesh. For making theoretical chemistry popular in Himachal Pradesh, Dr. Chakraborty has taken a large number of students from Himachal Pradesh for internships. Dr. Chakraborty coordinated* the first RSC-Salters' Chemistry Camp in Himachal Pradesh.
