Unraveling the Emergence of Slow Dynamics in U(1) Lattice Gauge Theories
Riccardo Andreoni, Zala Lenarčič, Zeno Bacciconi +3
The dynamics of gauge theories is of fundamental interest, with low-dimensional systems displaying a rich phenomenology beyond the rapid thermalization typical of QCD and non-Abeli…
On Rare Nonresonant Regions and Subdiffusive Transport in an Interacting Disordered Quantum Chain
A. Scardicchio, S. L. Sondhi
We study rare nonresonant regions in a canonical one-dimensional disordered quantum spin chain by directly implementing the iterated Schrieffer-Wolff construction underlying the re…
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…
On the Optimal Layout of Two-Dimensional Lattices for Density Matrix Renormalization Group
A. Scardicchio
For quantum spin models defined on a two-dimensional lattice, we look for the best numbering of the lattice sites (a layout) that, at fixed bond dimension and other parameters of t…
Exact results on the hydrodynamics of certain kinetically-constrained hopping processes
Adam J. McRoberts, Vadim Oganesyan, Antonello Scardicchio
We consider a model of interacting random walkers on a triangular chain and triangular lattice, where a particle can move only if the other two sites of the triangle are unoccupied…
