Krylov-Space Memory Cores
Mohsen Alishahiha, Mohammad Javad Vasli
The paper defines Krylov-space memory cores as stationary, depth‑resolved structures that pinpoint where anomalous quantum memory persists in the Krylov space of otherwise thermali…
Krylov Distribution and Spectral Convergence of Quantum Fisher Information
Mohsen Alishahiha, Fatemeh Tarighi Tabesh, Mohammad Javad Vasli
We establish a direct correspondence between the Krylov hierarchy of quantum Fisher information (QFI) and a Krylov-resolved decomposition of the symmetric logarithmic derivative (S…
Krylov Distribution
Mohsen Alishahiha, Mohammad Javad Vasli
We introduce the Krylov distribution , a static Krylov-space diagnostic that characterizes how inverse-energy response is organized in Hilbert space. The central o…
Scrambling Without Chaos in Random Free-Fermionic Systems
Ali Mollabashi, Mohammad-Javad Vasli
We study the role of randomness in the scrambling of quantum information within integrable free-fermionic systems. Considering quadratic Hamiltonians with varying degrees of random…
On Krylov Complexity as a Probe of the Quantum Mpemba Effect
Mohsen Alishahiha, Mohammad Javad Vasli
We investigate Krylov state complexity as a probe of the quantum Mpemba effect in quantum spin chains. For models without global symmetry, Krylov complexity exhibits clear M…
Krylov Complexity as a Probe for Chaos
Mohsen Alishahiha, Souvik Banerjee, Mohammad Javad Vasli
In this work, we explore in detail, the time evolution of Krylov complexity. We demonstrate, through analytical computations, that in finite many-body systems, while ramp and plate…
