Landau khalatnikov方程
TīmeklisObserved hysteresis loops usually look much thinner and sloped than Landau-Khalatnikov ones [2], [7], [9], [24], [25], [26]. Also equations of Landau-Khalatnikov type describe homogeneous pyroelectric coefficient switching with the sharp peak near the thermodynamic coercive field value. Tīmeklis2012. gada 15. jūn. · It can be described by Landau–Khalatnikov kinetics and takes place only for the external field larger than the coercive one. It is shown that for …

TīmeklisINVARIANT LANDAU–KHALATNIKOV THEORY Since the Ginzburg–Landau equation has proven to be very successful when applied to equi-librium superconductivity, it is reasonable to try to formulate a time-dependent theory based on this equation. Schmid [4] advanced the following gauge invariant modification of the theory [1,2]. Tīmeklis2024. gada 13. dec. · Abstract.

TīmeklisWe present the circuit equivalent of the Landau-Khalatnikov dynamical ferroelectric model. The differential equation for hysteretic behavior is subject to numerical computer simulations. The size and shape of the simulated hysteretic loops depend strongly on the frequency and the amplitude of the driving electric field.
