Key Points

  • The study shows that the critical dynamics at the tricritical point can still be described by finite-time scaling despite the breakdown of the Kibble-Zurek mechanism.
  • Key metrics include dimensions of driving rates: r μ = z + 1/ ν μ and r p = z + 1/ ν p, emphasizing distinct behavior along two independent directions.
  • Using a time-dependent variational principle, this research investigates dynamics near a one-dimensional supersymmetric Ising tricritical point.
  • The findings illuminate nonequilibrium critical dynamics and have implications for programmable quantum processors in Rydberg atomic systems.

Abstract

Abstract The conventional Kibble-Zurek (KZ) mechanism, describing driven dynamics across critical points based on the adiabatic-impulse scenario (AIS), has attracted broad attentions. However, the driven dynamics in the tricritical point with two independent relevant directions has not been adequately studied. Here, we employ time-dependent variational principle to study the driven critical dynamics at a one-dimensional supersymmetric Ising tricritical point. For the relevant direction along the Ising critical line, the AIS apparently breaks down. Nevertheless, we find that the critical dynamics can still be described by the finite-time scaling in which the driving rate has the dimension of r μ = z + 1/ ν μ with z and ν μ being the dynamic exponent and correlation length exponent in this direction, respectively. For driven dynamics along other direction, the driving rate has the dimension r p = z + 1/ ν p with ν p being the other correlation length exponent. Our work brings new fundamental perspective into the nonequilibrium critical dynamics near the tricritical point, which could be realized in programmable quantum processors in Rydberg atomic systems.
