Topological Control of Quantum Chaos Diagnostics: OTOCs, Spectral Statistics, and Information Scrambling in Ising Model
Reza Pirmoradian, Soheir Rouhani, M. Reza Tanhayi
We investigate the integrability-to-chaos transition and information scrambling in Ising spin networks via a graph-theoretic formulation. Modeling spins as vertices and interaction…

Entanglement Structure of Nonlocal Field Theories
Reza Pirmoradian, M. Hossein Bek-Khoshnevis, Sadaf Ebadi +1
Nonlocal interactions are known to generate volume-law entanglement entropy. However, their deeper impact on the fine structure of quantum correlations remains a key open question.…

Symmetry-Resolved Entanglement Entropy for Local and Non-local QFTs
Reza Pirmoradian, Mohammad Reza Tanhayi
In this paper, we investigate symmetry-resolved entanglement entropy (SREE) in free bosonic quantum many-body systems. Utilizing a lattice regularization scheme, we compute symmetr…
