Pseudo complexity of purification for free scalar field theories
Aranya Bhattacharya, Arpan Bhattacharyya, Sabyasachi Maulik
We compute the pseudo complexity of purification corresponding to the reduced transition matrices for free scalar field theories with an arbitrary dynamical exponent. We plot the b…

Operator growth and Krylov construction in dissipative open quantum systems
Aranya Bhattacharya, Pratik Nandy, Pingal Pratyush Nath +1
Inspired by the universal operator growth hypothesis, we extend the formalism of Krylov construction in dissipative open quantum systems connected to a Markovian bath. Our construc…
