About me

We are interested in quantum materials: materials that show fascinating behavior that cannot be explained with classical models. Our group focuses on growing them by flux-method and study them with a variety of tools, the primary of which is a scanning tunneling microscope which can perform atomic scale imaging at ultralow temperatures and high magnetic fields.

Biography

Rahul was born in the holy city of Varanasi, Uttar Pradesh. He received his school education at Kendriya Vidyalaya D.L.W. Varanasi up where he finished his std 12th in 2009. Then he moved to IIT-Bombay where he received a B.-Tech M-Tech. Dual Degree in Engineering Physics with a Minor in Electrical Engineering in 2014. He also ended up with the gold medal for the best academic performance across all streams in his class. His love for Physics took him for Ph.D. at Cornell Univeristy with Prof. Seamus Davis where he worked with a dilution fridge STM and completed his thesis titled "Advanced Quasiparticle Interference Imaging for Complex Superconductors" where he shed light on a long-standing problem of superconducting energy-gaps structure of Sr2RuO4 and a new technique to find phase of superconductors from STM imaging implemented on LiFeAs. Motivated by the fascinating world of quantum materials, Rahul moved to Quantum Materials Center, University of Maryland to work with Prof. Johnpierre Paglione on growing quantum materials using flux-growth technique and performing transport based experiments. He joined IISER Berhampur in August 2022 and has stayed here ever since. When not doing Physics, Rahul spends time in kitchen, philosophy and music.
