Dr. Rudra Shekhar MANNA

Assistant Professor

Education & Experience:

Ph.D.: Goethe University Frankfurt, Germany (2012)
M.Sc.: IIT Bombay
B.Sc.: RKM Vidyamandira, Belur Math, Calcutta University (2004)

Research Interests: 

Experimental condensed matter physics, particularly magnetism and superconductivity.
Experiment: strongly correlated electron phenomena, e.g., spin-orbit coupled iridates, triangular and kagome spin-liquid, Mott metal-insulator transition, superconductivity and magnetism by performing experiments at extreme conditions like very low temperatures, high magnetic fields and high pressures.
Theoretical modelling: First-principles density functional theory (DFT) for electronic band structure calculations focusing the magnetic and transport properties at ambient and finite pressures.
