Krylov-Space Memory Cores
Mohsen Alishahiha, Mohammad Javad Vasli
We introduce Krylov-space memory cores as stationary, depth-resolved structures that reveal how anomalous initial-state memory is organized inside the Krylov space of otherwise the…
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 ob…
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…
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…
Eigenstate Thermalization Hypothesis: A Primer
Mohsen Alishahiha, Mohammad Javad Vasli
How does an isolated quantum system evolve toward thermal equilibrium from a far-from-equilibrium initial state-for instance, one prepared by a global quantum quench? This question…
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…
Entanglement in Lifshitz Fermion Theories
Mohammad Javad Vasli, Komeil Babaei Velni, M. Reza Mohammadi Mozaffar +1
We study the static entanglement structure in (1+1)-dimensional free Dirac-fermion theory with Lifshitz symmetry and arbitrary integer dynamical critical exponent. This model is di…
Thermalization in Krylov Basis
Mohsen Alishahiha, Mohammad Javad Vasli
We study thermalization in closed non-integrable quantum systems using the Krylov basis. We demonstrate that for thermalization to occur, the matrix representation of typical local…
Krylov Complexity in Lifshitz-type Scalar Field Theories
M. J. Vasli, K. Babaei Velni, M. R. Mohammadi Mozaffar +2
We investigate various aspects of the Lanczos coefficients in a family of free Lifshitz scalar theories, characterized by their integer dynamical exponent, at finite temperature. I…
Holographic Study of Reflected Entropy in Anisotropic Theories
Mohammad Javad Vasli, M. Reza Mohammadi Mozaffar, Komeil Babaei Velni +1
We evaluate reflected entropy in certain anisotropic boundary theories dual to nonrelativistic geometries using holography. It is proposed that this quantity is proportional to the…
Entanglement Wedge Cross Section in Holographic Excited States
Mohammad Sahraei, Mohammad Javad Vasli, M. Reza Mohammadi Mozaffar +1
We evaluate the entanglement wedge cross section (EWCS) in asymptotically AdS geometries which are dual to boundary excited states. We carry out a perturbative analysis for calcula…
