Ritam Chakraborty pursuing Ph.D.


Ritam did his schooling from Baranagar Ramakrishna Mission Ashrama High School, Kolkata, West Bengal. He obtained his B.Sc.(with Physics major) degree from Jadavpur University, Kolkata in 2017. Subsequently, he got masters in Physics from the same university in 2019.

Ritam joined the Computational Nanoscience group supervised at JNCASR in September,2020.

 Research Interests: 

The interfaces of dye molecules and metal surfaces have unique properties that can be exploited in constructing novel devices. Ritam is using density functional theory to study such systems, motivated by scanning tunneling microscopy (STM) experiments performed in the group of Anthoula Papageorgiou and Johannes Barth at the Technical University, Munich, Germany.

Ritam's extracurricular interests are music, football and food (especially pizza and pasta!) He is looking forward to his first scientific visit to Germany this summer, which will also give him an opportunity to visit Allianz Arena in Munich.

Arpan Das pursuing Ph.D.

Education: Arpan did his schooling from Deulpur High School, Panchla, Howrah, West Bengal. Then he completed his B.Sc. degree in Physics from Uluberia College, Howrah (University of Calcutta) in 2016. He went on to do his masters in Physics from Ramakrishna Mission Residential College, Narendrapur (University of Calcutta) in 2018.

Arpan joined the Computational Nanoscience group at JNCASR for pursuing PhD in August 2018. 

Research interests:

Arpan is simultaneously working on several projects. In all of these, he uses density functional theory (DFT) to see how the lowering of dimensionality affects structural, electronic, magnetic and chemical properties of materials at the nanoscale. These projects are in close collaboration with experimental groups.

Arpan is looking at thin film growth and the formation of surface alloys when one metal is deposited on another. This work is done in collaboration with the group of Prof. Krishna Kumar Menon at the Saha Institute, Kolkata, who perform low energy electron diffraction (LEED) and Angle-Resolved Photo Emission Spectroscopy (ARPES) experiments to study such systems.

Arpan is using DFT and Density Functional Perturbation Theory (DFPT) to study the photoluminescence and optical properties of doped perovskites. This project is in collaboration with the group of Prof. Ranjani Viswanatha, JNCASR, Bangalore. 

Arpan is also using DFT to study the magnetic and electronic properties of the two dimensional electron gas (2DEG) formed at certain oxide interfaces. This project is in collaboration with the group of Prof. Suvankar Chakraverty, INST, Mohali. 

In addition to loving physics, Arpan is particularly happy when he is eating good food. He believes that Bengali food is the best!
