Krylov Complexity for Open Quantum System: Dissipation and Decoherence
Arpan Bhattacharyya, Sayed Gool, S. Shajidul Haque
We investigate Krylov complexity in open quantum systems using Lindblad master equations for bosonic bath models, with particular emphasis on the Caldeira--Leggett model. Krylov co…

Probing the self-coherence of primordial quantum fluctuations with complexity
Arpan Bhattacharyya, Suddhasattwa Brahma, S. Shajidul Haque +2
A smoking gun for our current paradigm of the early universe would be direct evidence for the quantum mechanical origin of density perturbations which are conjectured to seed the l…
