Name of the candidate: Dr. Krishnendu Kundu
About the Speaker: Dr. Krishnendu Kundu is an EPR spectroscopist. He obtained his PhD in Chemistry from TIFR-Mumbai under the guidance of Prof. Ranjan Das. Then, he shifted to the Weizmann Institute of Science, Israel worked with the late Prof. Shimon Vega and Prof. Daniella Goldfarb, and developed a theory of a very popular EPR-NMR hybrid technique, utilized to enhance NMR signal. Subsequently, Dr. Kundu moved to the National High Magnetic Field Laboratory, Tallahassee, and worked in quantum information sciences with Prof. Stephen Hill. In addition to focusing on magnetic resonance, he also has a keen interest in teaching, popularizing science, and designing laboratory experiments for the school and undergraduate levels.
Title of the talk: Applications of EPR Spectroscopy in Quantum Information Sciences and Enhancing NMR Sensitivity
Abstract of the talk: Electron spins in molecules have been proposed as potential qubits in quantum computers. But quantumness (coherence) of electron spin is very fragile due to several types of magnetic fluctuations present in EPR experiments. However, engineering on the spin energy-levels can protect (partially) the spin-coherence against magnetic noise. I will briefly discuss the success and challenges of this approach in the context of coherence enhancement.
Additionally, I will briefly talk about the Dynamic Nuclear Polarisation (DNP) technique, which is widely used to enhance NMR signal by several orders of magnitude utilizing EPR technique. The focus will be on the mechanistic details of the process, emphasizing the role of (double resonance) EPR spectroscopy to substantiate the theory.
Furthermore, I will discuss a recent hardware development in implementing frequency-swept (chirp) technique in EPR to enable a conventional EPR spectrometer to perform in the Fourier Transform domain.
