Kibble-Zurek mechanism is a theory of defect formation in a non-equilibrium continuous phase transition. So far the theory has been successfully tested by numerical simulations and condensed matter experiments in a number of systems with small thermal fluctuations. This paper reports first numerical ...
The transition out of the period-four phase is the main focus of the rest of this section. Our first task is to locate the point on the phase boundary where the chiral perturbation vanishes, hence where the transition can be expected to be described by a conformal field theory. Note that ...
近年来,他的研究领域主要集中在引力全息原理在非平衡态中的应用,尤其在全息Kibble-Zurek机制方面做了一定的工作。他与合作者率先研究了拓扑缺陷在全息超导体中的形成,发现缺陷的数目满足Kibble-Zurek机制;但是,当规范场的贡献更大时,Kibble-Zurek机制将会被Flux-Trapping机制所取代,则拓扑缺陷就会形成同号的簇分布。
Now we consider a fully PT-symmetric Kibble–Zurek problem, when the instantaneous spectrum is always real. We choose Δ = Δ0, Γ = Δ0t/τsuch that the time evolution ends exactly at an EP. The spin expectation values are 〈σy(τ)〉 + Δ0ln(W/Δ0)/π ~ τ...

The results support the adiabatic-impulse approximation, which is the core of Kibble–Zurek theory. Moreover, the developed high-fidelity multistage optical interferometer can support more complex linear optical quantum simulations.Xiao-YeXu

ZurekmechanismThe Kibble Zurek mechanism in a relativistic ?~4 scalar field theory in D = (1 + 1) is studied using uniform matrix product states. The equal time two point function in momentum space G_2(k) is approximated as the system is driven through a quantum phase transition at a ...
In the limiting cases of overdamped and underdamped dynamics, the Fokker-Planck method confirms the theoretical predictions of the Kibble-Zurek scaling theory. The developed framework is computationally efficient, enables the prediction of finite-size scaling functions, and is applicable to microscopic ...
