Unraveling the Emergence of Slow Dynamics in U(1) Lattice Gauge Theories
Riccardo Andreoni, Zala Lenarčič, Zeno Bacciconi +3
The dynamics of gauge theories is of fundamental interest, with low-dimensional systems displaying a rich phenomenology beyond the rapid thermalization typical of QCD and non-Abeli…

Confinement and string breaking are two fundamental phenomena in gauge theories. Signatures of both are currently pursued in quantum-simulator experiments, opening a new angle on s…
Superdiffusion and anomalous fluctuations in chiral integrable dynamics
Cristiano Muzzi, Devendra Singh Bhakuni, Marcello Dalmonte +2
Symmetries strongly influence transport properties of quantum many-body systems, and can lead to deviations from the generic case of diffusion. In this work, we study the impact of…
Anomalously fast transport in non-integrable lattice gauge theories

We investigate the electric-field driven power-law random banded matrix(PLRBM) model where a variation in the power-law exponent yields a delocalization-to-localization phase t…
Local vs non-local dynamics in cavity-coupled Rydberg atom arrays
Zeno Bacciconi, Hernan B. Xavier, Matteo Marinelli +2
Locality is a transversal principle that governs quantum dynamics of many-body systems. However, for cavity embedded systems, such fundamental notion is hindered by the presence of…
