The Lattice Schwinger Model and Its Quantum Simulation
Joao C. Pinto Barros, Pierpaolo Fontana, Pasquale Sodano +1
In this chapter we review results on the lattice Schwinger model. In par-ticular, we show how the effect of the anomaly is reproduced on the lattice. We connect these results to re…
Renormalized dual basis for scalable simulations of 2+1D compact quantum electrodynamics
Marc Miranda-Riaza, Pierpaolo Fontana, Alessio Celi
The classical and quantum simulation of lattice gauge theories (LGTs) with Lie groups is hindered by the infinite-dimensional Hilbert space of gauge degrees of freedom. In a recent…
An efficient finite-resource formulation of non-Abelian lattice gauge theories beyond one dimension
Pierpaolo Fontana, Marc Miranda Riaza, Alessio Celi
Non-Abelian gauge theories provide the most accurate description of fundamental interactions, showing remarkable agreement with experimental data in cosmology and particle physics.…
Reformulation of gauge theories in terms of gauge invariant fields
Pierpaolo Fontana, Joao C. Pinto Barros, Andrea Trombettoni
We present a reformulation of gauge theories in terms of gauge invariant fields. Focusing on Abelian theories, we show that the gauge and matter covariant fields can be recombined…
