Dependence of Krylov complexity on the initial operator and state
Sreeram PG, J. Bharathi Kannan, Ranjan Modak +1
Krylov complexity, a quantum complexity measure which uniquely characterizes the spread of a quantum state or an operator, has recently been studied in the context of quantum chaos…

Periodicity of dynamical signatures of chaos in quantum kicked top
Sreeram PG, M. S. Santhanam
A host of dynamical measures of quantum correlations -- out-of-time ordered correlators (OTOC), Loschmidt echo, generalized entanglement and observational entropy -- are useful to…

Probing the localization effects in Krylov basis
J. Bharathi Kannan, Sreeram PG, Sanku Paul +2
Krylov complexity (K-complexity) is a measure of quantum state complexity that minimizes wavefunction spreading across all the possible bases. It serves as a key indicator of opera…
