Modular Krylov Complexity as a Boundary Probe of Area Operator and Entanglement Islands
Niloofar Vardian
We show that the area operator of a quantum extremal surface can be reconstructed directly from boundary dynamics without reference to bulk geometry. Our approach combines the oper…

Generalized Krylov Complexity
Amin Faraji Astaneh, Niloofar Vardian
We extend the concept of Krylov complexity to include general unitary evolutions involving multiple generators. This generalization enables us to formulate a framework for generali…

Average Spread Complexity and the Higher-Order Level Spacing
Amin Faraji Astaneh, Niloofar Vardian
We investigate the spread complexity of a generic two-level subsystem of a larger system to analyze the influence of energy level statistics, comparing chaotic and integrable syste…
