Hilbert curve vs Hilbert space: exploiting fractal 2D covering to increase tensor network efficiency
Giovanni Cataldi, Ashkan Abedi, Giuseppe Magnifico +4
We present a novel mapping for studying 2D many-body quantum systems by solving an effective, one-dimensional long-range model in place of the original two-dimensional short-range…

Real Time Dynamics and Confinement in the Schwinger-Weyl lattice model for 1+1 QED
Giuseppe Magnifico, Marcello Dalmonte, Paolo Facchi +3
We study the out-of-equilibrium properties of dimensional quantum electrodynamics (QED), discretized via the staggered-fermion Schwinger model with an Abelian $\mathbb{Z}_{n}…
