Hadrons in (1+1)D Hamiltonian hardcore lattice QCD
Marco Rigobello, Giuseppe Magnifico, Pietro Silvi +1
We study 2-flavor Hamiltonian lattice QCD in (1+1)D with hardcore gluons, at zero and finite density, by means of matrix product states. We introduce a formulation of the theory wh…
A relativistic discrete spacetime formulation of 3+1 QED
Nathanaël Eon, Giuseppe Di Molfetta, Giuseppe Magnifico +1
This work provides a relativistic, digital quantum simulation scheme for both and dimensional quantum electrodynamics (QED), based on a discrete spacetime formulation o…
Unsupervised and supervised learning of interacting topological phases from single-particle correlation functions
Simone Tibaldi, Giuseppe Magnifico, Davide Vodola +1
The recent advances in machine learning algorithms have boosted the application of these techniques to the field of condensed matter physics, in order e.g. to classify the phases o…
Adaptive-weighted tree tensor networks for disordered quantum many-body systems
Giovanni Ferrari, Giuseppe Magnifico, Simone Montangero
We introduce an adaptive-weighted tree tensor network, for the study of disordered and inhomogeneous quantum many-body systems. This ansatz is assembled on the basis of the random…
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…
Lattice Quantum Electrodynamics in (3+1)-dimensions at finite density with Tensor Networks
Giuseppe Magnifico, Timo Felser, Pietro Silvi +1
Gauge theories are of paramount importance in our understanding of fundamental constituents of matter and their interactions. However, the complete characterization of their phase…
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}…
Entanglement topological invariants for one-dimensional topological superconductors
Pierre Fromholz, Giuseppe Magnifico, Vittorio Vitale +2
Entanglement is known to serve as an order parameter for true topological order in two-dimensional systems. We show how entanglement of disconnected partitions defines topological…
Topological phases in two-legged Heisenberg ladders with alternating interactions
Greta Ghelli, Giuseppe Magnifico, Cristian Degli Esposti Boschi +1
We analyze the possible existence of topological phases in two-legged spin ladders considering a staggered interaction in both chains. When the staggered interaction in one chain i…
gauge theories coupled to topological fermions: QED with a quantum-mechanical angle
G. Magnifico, D. Vodola, E. Ercolessi +3
We present a detailed study of the topological Schwinger model [Phys. Rev. D 99, 014503 (2019)], which describes (1+1) quantum electrodynamics of an Abelian gauge field coup…
Diagnosing Potts criticality and two-stage melting in one-dimensional hard-boson models
Giuliano Giudici, Adriano Angelone, Giuseppe Magnifico +4
We investigate a model of hard-core bosons with infinitely repulsive nearest- and next-nearest-neighbor interactions in one dimension, introduced by Fendley, Sengupta and Sachdev i…
Symmetry-protected topological phases in lattice gauge theories: topological QED
G. Magnifico, D. Vodola, E. Ercolessi +3
The interplay of symmetry, topology, and many-body effects in the classification of possible phases of matter poses a formidable challenge that is attracting great attention in con…
Phase Transitions in Gauge Models: Towards Quantum Simulations of the Schwinger-Weyl QED
Elisa Ercolessi, Paolo Facchi, Giuseppe Magnifico +2
We study the ground-state properties of a class of lattice gauge theories in 1 + 1 dimensions, in which the gauge fields are coupled to spinless fermionic matter. Th…
