Arpan Bhattacharyya
IIT-Gandhinagar
After completing a Ph.D. from the Centre for High Energy Physics at the Indian Institute of Science, Bengaluru, in 2015, Arpan joined as a postdoctoral fellow at Fudan University, China. He was a JSPS Postdoctoral Fellow at the Yukawa Institute for Theoretical Physics at Kyoto University, Japan. Presently, he is an Assistant Professor in the Physics Department of IIT-Gandhinagar. His research interests include the application of quantum information in quantum many-body systems and quantum gravity (AdS/CFT), as well as understanding gravitational wave physics through the lens of scattering amplitude. He was selected Associate of IASc in 2023.

Some Explorations into Krylov/Spread Complexity
Motivated by recent progress in understanding quantum chaos through the notion of operator growth, we explore some applications of Krylov complexity/spread complexity for certain quantum many-body systems and probe their dynamics (in both open and closed setups) through the complexity and see what interesting lesson we can learn from this.
