Nitin Gupta is a postdoctoral fellow at HKUST, where his research spans quantum chaos and phase transitions. His current work centres on Krylov complexity—a recently introduced quantity serving as a generic order parameter for diverse quantum phase transitions. In earlier collaborations, Gupta demonstrated the effectiveness of Krylov complexity in diagnosing dynamical PT-symmetric and topological phase transitions in paradigmatic quantum many-body models, including the linearly coupled Bateman oscillator and the Kitaev chain. His methodological approach combines analytical techniques with, more recently, numerical simulations. Gupta has also cultivated a growing interest in the topological aspects of quantum field theory in many-body systems.
