Vanishing spin stiffness in weakly disordered two-dimensional Heisenberg ferromagnets

Jacopo Niedda, Aldo Coraggio, Giacomo Bracci-Testasecca +1

We show that a small fraction of antiferromagnetic bonds qualitatively alters the long-wavelength dynamics of two-dimensional Heisenberg ferromagnets. Although the classical ground…

Semiclassical picture of the Heisenberg spin glass in two dimensions: from weak localization to hydrodynamics

Giacomo Bracci-Testasecca, Jacopo Niedda, Aldo Coraggio +2

The two-dimensional Heisenberg spin-glass model is investigated by means of a semiclassical expansion around classical states. At leading order, we obtain an effective quadratic sp…

Quantum Spin Glass in the Two-Dimensional Disordered Heisenberg Model via Foundation Neural-Network Quantum States

Luciano Loris Viteritti, Riccardo Rende, Giacomo Bracci-Testasecca +4

We investigate the two-dimensional frustrated quantum Heisenberg model with bond disorder on nearest-neighbor couplings using the recently introduced Foundation Neural-Network Quan…
