An exact treatment of the Anderson Hasegawa two site model, incorporating the presence of superexchange and polarons, is used to compute the heat capacity. The calculated results point to the dominance of the lattice contribution, especially in the ferromagnetic regime. This behavior is in qualitative agreement with experimental findings.

متن کاملThe Parabolic Anderson Model
This is a survey on the intermittent behavior of the parabolic Anderson model, which is the Cauchy problem for the heat equation with random potential on the lattice Z. We first introduce the model and give heuristic explanations of the long-time behavior of the solution, both in the annealed and the quenched setting for time-independent potentials. We thereby consider examples of potentials st...
متن کاملThe heat capacity of the restricted primitive model electrolyte
The constant-volume heat capacity, CV(T ,r), of the restricted primitive model ~RPM! electrolyte is considered in the vicinity of its critical point. It is demonstrated that, despite claims, recent simulations for finite systems do not convincingly indicate the absence of a divergence in CV(T ,r)—which would point to non-Ising-type criticality. The strong qualitative difference between CV for t...
متن کاملDynamic Heat Capacity of the East Ising Model
It has been shown in experiment that the heat capacity of glass formers has a frequency dependence, this is called the dynamic heat capacity. The dynamic heat capacity for a simple spin model known to be a glass former, the east Ising model, is measured by simulation. The result shows stretched exponential decay like relaxation, and the data is fit to the appropriate form. For low temperatures,...
متن کاملHeat capacity in proteins.
Heat capacity (Cp) is one of several major thermodynamic quantities commonly measured in proteins. With more than half a dozen definitions, it is the hardest of these quantities to understand in physical terms, but the richest in insight. There are many ramifications of observed Cp changes: The sign distinguishes apolar from polar solvation. It imparts a temperature (T) dependence to entropy an...
