Complexity of PXP scars revisited
Pawel Caputa, Xuhao Jiang, Sinong Liu
We revisit a quantum quench scenario in which either a scarring or thermalizing initial state evolves under the PXP Hamiltonian. Within this framework, we study the time evolution…

Krylov complexity of density matrix operators
Pawel Caputa, Hyun-Sik Jeong, Sinong Liu +2
Quantifying complexity in quantum systems has witnessed a surge of interest in recent years, with Krylov-based measures such as Krylov complexity () and Spread complexity ($C_…
