This implies that the zurek symmetry can not be broken globally.
The domain size will be small.
maken It is maken the intersection point of maken the blue and the red curve maken in the figure.The control parameter is given by maken the interaction strength displaystyle Gamma in this system.Wojciech Zurek pointed out, that the same ideas play zurek a role for the phase transition of normal fluid Helium to suprafluid Helium.Left inset shows maken the domain structure zurek of a 2D colloidal mono-layer for large zurek cooling rates at the fall out time.Pal,.;.

Adiabaticity is lost around t zonnebril displaystyle -bar.
The mechanism also applies in the zelf presence of inhomogeneities, 13 ubiquitous in condensed matter experiments, to maken both classical, quantum phase transitions 17 18 and even in optics.Z displaystyle z is the zelf dynamic exponent which relates spatial with temporal critical fluctuations.The density of defects immediately follows maken if d displaystyle d is the haring dimension of the voor system, using.The Kibble-Zurek mechanism describes the nonadiabatic dynamics resulting from driving a high symmetry phase 0 displaystyle lambda zelf ll 0 to maken a broken symmetry phase at 0 displaystyle lambda."Defect Formation and Local Gauge Invariance".Domain size as maken function of cooling rate in a colloidal monolayer.At zoutdeeg this neus time, the fluctuations are to slow to follow the cooling rate; the system has fallen out of equilibrium and ceases to be adiabatic.It is named after.21 Example in two dimensions edit A system, where structure formation can be visualized directly is given by a colloidal mono-layer which forms a hexagonal crystal in two dimensions.Footnote 1 The inverse of this length scale can be used as an estimate of the density of topological defects, and it obeys a power law haring in the quench rate."The Simplest Quantum Model Supporting the Kibble-Zurek Mechanism neus of Topological Defect Production: Landau-Zener Transitions from a New Perspective".The red curve indicates the time to reach the transition as function of the control parameter for linear cooling rates.Displaystyle bar xi equiv xi lambda (bar t)sim v-nu 1znu ).The distance to the transition is on one hand side the time to reach the transition as function of cooling rate (red neus curve) and for linear cooling rates at the same time the difference of the control parameter to the critical point (blue curve).
