Anharmonic Crystals

A unified theory of phase transitions and quantum effects in quantum anharmonic crystals is presented. In its framework, the relationship between these two phenomena is analyzed. The theory is based on the representation of the model Gibbs states in terms of path measures (Euclidean Gibbs measures). It covers the case of crystals without translation invariance, as well as the case of asymmetric anharmonic potentials. The results obtained are compared with those known in the literature.

In Infants And Children

In the forward Frederic A. Gibbs states "Changed attitudes toward feeblemindedness allow the present text to start from a simple, logical, and completely realistic premise, viz., that mental retardation is due to brain disorder." Hopefully, many more physicians accept this statement as correct, but it is unfortunately clear that there are still many physicians who have not yet accepted the fact that mental retardation is a reasonable and profitable area of concern and investigation. The authors carefully and persistently present the mass of information now available to support Gibbs' statement.

Classical Particles

We present two independent approaches for computing the thermodynamics for classical particles interacting via the Moser-Calogero potential Combining the results we conjecture the form of equation of state or, what is equivalent, the asymptotics of the Jacobian between volume elements corresponding to two symplectic structures on the phase space.

Transport Maps

We construct non-commutative analogs of transport maps among free Gibbs state satisfying a certain convexity condition. Unlike previous constructions, our approach is non-perturbative in nature and thus can be used to construct transport maps between free Gibbs states associated to potentials which are far from quadratic, i.e., states which are far from the semicircle law. An essential technical ingredient in our approach is the extension of free stochastic analysis to non-commutative spaces of functions based on the Haagerup tensor product.
