Symmetry-Resolved Spread Complexity
Pawel Caputa, Giuseppe Di Giulio, Tran Quang Loc
In this work, we investigate the impact of conserved charges on the dynamics of spread complexity of quantum states. Building on the notion of symmetry-resolved Krylov complexity […
Growth of block diagonal operators and symmetry-resolved Krylov complexity
Pawel Caputa, Giuseppe Di Giulio, Tran Quang Loc
This work addresses how the growth of invariant operators is influenced by their underlying symmetry structure. For this purpose, we introduce the symmetry-resolved Krylov complexi…
Local Quenches from a Krylov Perspective
Pawel Caputa, Giuseppe Di Giulio
In this work, we investigate local quench dynamics in two-dimensional conformal field theories using Krylov space methods. We derive Lanczos coefficients, spread complexity, and Kr…
Measurement-induced symmetry restoration and quantum Mpemba effect
Giuseppe Di Giulio, Xhek Turkeshi, Sara Murciano
Monitoring a quantum system can profoundly alter its dynamical properties, leading to nontrivial emergent phenomena. In this work, we demonstrate that dynamical measurements strong…
Continuous majorization in quantum phase space for Wigner-positive states and proposals for Wigner-negative states
Jan de Boer, Giuseppe Di Giulio, Esko Keski-Vakkuri +1
In quantum resource theory, one is often interested in identifying which states serve as the best resources for particular quantum tasks. If a relative comparison between quantum s…
Wormhole-induced effective coupling in SYK chains
Pablo Basteiro, Giuseppe Di Giulio, Johanna Erdmenger +2
Inhomogeneous quantum chains have recently been considered in the context of developing novel discrete realizations of holographic dualities. To advance this programme, we explore…
On entanglement hamiltonians of an interval in massless harmonic chains
Giuseppe Di Giulio, Erik Tonni
We study the continuum limit of the entanglement hamiltonians of a block of consecutive sites in massless harmonic chains. This block is either in the chain on the infinite line or…
