Dr Subhasish Saha

About

Hi, I am Dr. Subhasish Saha, with expertise in theoretical physics, focusing on teaching, research, and mentoring students. I obtained my Ph.D. in Physics from the Indian Institute of Technology (IIT) Patna, specializing in electronic structure and photoionization dynamics of confined atomic systems using advanced relativistic many-body methods. After completing my Ph.D., I joined The Ohio State University, USA, as a Postdoctoral Researcher, where I continued my research in computational atomic physics. Subsequently, I worked as a Postdoctoral Researcher at the Indian Institute of Science Education and Research (IISER) Kolkata, where my research expanded into computational molecular physics and the theoretical design of organic light-emitting diode (OLED) materials. Prior to joining RV University, I served as an Assistant Professor at MLR Institute of Technology, Hyderabad, teaching undergraduate engineering physics and mentoring student research projects..

Teaching has always been an integral part of my academic career. I enjoy creating an interactive learning environment that encourages curiosity, critical thinking, and scientific reasoning. My teaching interests include Quantum Mechanics, Classical Mechanics, Electromagnetic Theory, Mathematical Physics, Thermodynamics and Statistical Mechanics, Solid State Physics, Atomic and Molecular Physics, Electronics, and Special Theory of Relativity. I strive to make complex physical concepts accessible by combining theoretical foundations with computational techniques and real-world applications. I also look forward to mentoring undergraduate, postgraduate, and doctoral students in their academic and research pursuits.

My research interests lie in computational atomic and molecular physics, quantum mechanics, and quantum materials. During my doctoral research, I employed advanced many-body relativistic methods such as the Relativistic Random Phase Approximation (RRPA) and Multi-Configuration Dirac–Fock (MCDF) theory to investigate the electronic structure, electron correlation, and photoionization dynamics of free and endohedrally confined atomic systems. My postdoctoral research further broadened my expertise to include wavefunction-based quantum chemical methods, Density Functional Theory (DFT), and Time-Dependent Density Functional Theory (TDDFT) for understanding excited-state properties and screening high-performance OLED materials.

At RV University, I aim to build an active and collaborative research programme in computational quantum science, establish interdisciplinary collaborations, attract externally funded research projects, and contribute to the growth of teaching, research, and innovation. I am committed to mentoring the next generation of scientists by fostering an environment that promotes scientific curiosity, creativity, and excellence in both teaching and research.
