Quantum Resources in Disorder-Free Localization Dynamics of Gauge Theories
Devendra Singh Bhakuni, Giovanni Cataldi, Jad C. Halimeh +1
Quantum-state complexity diagnostics provide valuable insight into many-body dynamics, information scrambling, and quantum computation. Here, we investigate the real-time dynamics…
Disorder-Free Localization and Fragmentation in a Non-Abelian Lattice Gauge Theory
Giovanni Cataldi, Giuseppe Calajó, Pietro Silvi +2
We investigate how isolated quantum many-body systems dynamically equilibrate under non-Abelian gauge-symmetry constraints. By encoding gauge superselection sectors into static $\m…
Real-Time String Dynamics in a D Non-Abelian Lattice Gauge Theory: String Breaking, Glueball Formation, Baryon Blockade, and Tension Reduction
Giovanni Cataldi, Simone Orlando, Jad C. Halimeh
Understanding flux string dynamics can provide insight into quark confinement and hadronization. First-principles quantum and numerical simulations have mostly focused on toy-model…
Optimal local basis truncation of lattice quantum many-body systems
Peter Majcen, Giovanni Cataldi, Pietro Silvi +1
We show how to optimally reduce the local Hilbert basis of lattice quantum many-body (QMB) Hamiltonians. The basis truncation exploits the most relevant eigenvalues of the estimate…
Hamiltonian Lattice Gauge Theories: emergent properties from Tensor Network methods
Giovanni Cataldi
This thesis develops advanced Tensor Network (TN) methods to address Hamiltonian Lattice Gauge Theories (LGTs), overcoming limitations in real-time dynamics and finite-density regi…
Quantum Many-Body Scarring in a Non-Abelian Lattice Gauge Theory
Giuseppe Calajò, Giovanni Cataldi, Marco Rigobello +5
Quantum many-body scarring (QMBS) is an intriguing mechanism of weak ergodicity breaking that has recently spurred significant attention. Particularly prominent in Abelian lattice…
