Low Temperature Smoothness of the Pressure for Antiferromagnets and other Models
نویسندگان
چکیده
We prove under certain conditions on a grandcanonical Hamiltonian that at low temperature the pressure is infinitely differentiable with respect to the inverse temperature and other parameters in the Hamiltonian, when the parameters are chosen so that the number of Gibbs states is at least equal to the number of ground states. Applications are made to Antiferromagnets and hard-core gases.

Optimization of Low Pressure Vortex Tube via Different Axial Angles of Injection Nozzles
In this article, a Ranque–Hilsch Vortex Tube has been optimized utilizing axial angles for nozzles. Effect of nozzles angles on the flow behavior has been investigated by computational fluid dynamics (CFD) techniques. A finite volume approach with the standard k–ε turbulence model has been used to carry out all the computations. The dimensions of studied vortex tubes are kept the same for all m...
