One-dimensional extended Hubbard model with soft-core potential
Thomas Botzung, Guido Pupillo, Pascal Simon +2
We investigate the phase diagram of a variant of the one-dimensional extended Hubbard model where particles interact via a finite-range soft-shoulder potential. Using Density…
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}…
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…
