Thermodynamics of thermal CVD process by thermodynamics, phase diagram, and transfer rate theory.

Thermodynamics of the UPt3 superconducting phase diagram.

Irreversible Thermodynamics and Rate Theory.

Introduction.-The "classical theory of irreversible thermodynamics"1 may be said to have its origin in the formulation of the "reciprocity relations" by Onsager.2 The basis of this theory may be summarized briefly as follows (for a complete discussion see works cited in ref. 1 and 2): in the limit of small excursions from thermodynamic equilibrium, changes in the properties of any system are de...

Variational theory for thermodynamics of thermal waves.

We discuss description of macroscopic representations of thermal fields with finite signal speed by composite variational principles involving suitably constructed potentials along with original physical variables. A variational formulation for a given vector field treats all field equations as constraints that are linked by Lagrange multipliers to the given kinetic potential. We focus on the e...

Thermodynamics and phase diagram of high temperature superconductors.

Thermodynamic quantities are derived for superconducting and pseudogap regimes by taking into account both amplitude and phase fluctuations of the pairing field. In the normal (pseudogap) state of the underdoped cuprates, two domains have to be distinguished: near the superconducting region, phase correlations are important up to temperature T(phi). Above T(phi), the pseudogap region is determi...

Information theory and Thermodynamics

A communication theory for a transmitter broadcasting to many receivers is presented. In this case energetic considerations cannot be neglected as in Shannon theory. It is shown that, when energy is assigned to the information bit, information theory complies with classical thermodynamic and is part of it. To provide a thermodynamic theory of communication it is necessary to define equilibrium ...
