Understanding real-time string dynamics in three spatial dimensions is essential for connecting quantum simulations of lattice gauge theories (LGTs) to the physical dimensionality…
Statistics as a local phase: crystalline order and quench dynamics of emergent dimers in Ising gauge theories

How does the Bose or Fermi statistics of microscopic particles survive when confinement binds them into emergent bosonic composites? We address this question in the strong-coupling…
Observation of far-from-equilibrium scaling in the transient dynamics of 2D quantum magnets
Fabio Bensch, Umberto Borla, Federico Balducci +7
The transient regime of far-from-equilibrium quantum many-body dynamics lacks the established organizing principles that universality and scaling provide in equilibrium. It is leas…
