Arnab Sarkar

About

Dr. Arnab Sarkar is a postdoctoral researcher in the Ultrafast Science of Quantum Materials (USQM) group, led by Prof. Allan Stewart Johnson, at IMDEA Nanociencia, Madrid, Spain. His research focuses on X-ray coherent imaging and ultrafast magnetism measurements. He earned his Ph.D. from the Indian Institute of Technology Kanpur, where he investigated nonlinear dynamics in nano-electromechanical systems, including the observation of time crystals in classical NEMS devices. He holds a master's degree in physics from the Indian Institute of Technology Bombay. Dr. Sarkar specializes in the application of ultrafast X-ray coherent imaging to explore quantum materials and advanced measurement techniques.
