Ramping through an extensively degenerate point eliminates Kibble-Zurek scaling and damps Stückelberg oscillations, while square-pulse driving at commensurate frequencies creates an approximate emergent U(1) symmetry.
In contrast to the ramp studied earlier where the system passes through the degenerate point only once, these features depend sensitively on τ

Quantum dynamics of a spin model with an extensive degeneracy
Ramping through an extensively degenerate point eliminates Kibble-Zurek scaling and damps Stückelberg oscillations, while square-pulse driving at commensurate frequencies creates an approximate emergent U(1) symmetry.
