Devvrat Tiwari

I am a PhD student at the Indian Institute of Technology Jodhpur (IITJ), where I focus on quantum chaos and thermodynamics. My research aims to investigate the thermodynamics of strongly coupled quantum systems to create practical quantum thermal devices. Furthermore, I am captivated by quantum chaos, which entails the investigation of the quantum physics of classically chaotic systems and the rate of information scrambling in a quantum system. I aspire to make significant contributions to these and related fields.
