Complexity in two-point measurement schemes
Ankit Gill, Kunal Pal, Kuntal Pal +1
We show that the characteristic function of the probability distribution associated with the change of an observable in a two-point measurement protocol with a perturbation can be…
Spread complexity evolution in quenched interacting quantum systems
Mamta Gautam, Kunal Pal, Kuntal Pal +3
We analyse time evolution of spread complexity (SC) in an isolated interacting quantum many-body system when it is subjected to a sudden quench. The differences in characteristics…
Spread Complexity in free fermion models
Mamta Gautam, Nitesh Jaiswal, Ankit Gill
We study spread complexity and the statistics of work done for quenches in the three-spin interacting Ising model, the XY spin chain, and the Su-Schrieffer-Heeger model. We study t…
Time evolution of spread complexity and statistics of work done in quantum quenches
Kuntal Pal, Kunal Pal, Ankit Gill +1
We relate the probability distribution of the work done on a statistical system under a sudden quench to the Lanczos coefficients corresponding to evolution under the post-quench H…
