Why must we work in the phase space? [PDF]

open access: yes, 2014
We are going to prove that the phase-space description is fundamental both in the classical and quantum physics. It is shown that many problems in statistical mechanics, quantum mechanics, quasi-classical theory and in the theory of integrable systems ...

Understanding quantum mechanics: a review and synthesis in precise language

open access: yesOpen Physics, 2019
This review, of the understanding of quantum mechanics, is broad in scope, and aims to reflect enough of the literature to be representative of the current state of the subject.

On the statistical mechanics of an adiabatic ensemble

open access: yesCondensed Matter Physics, 2004
Different descriptions of an adiabatic process based on statistical thermodynamics and statistical mechanics are discussed. Equality of the so-called adiabatic and isolated susceptibilities and its generalization as well as adiabatic invariants are ...

The BBGKY hierarchy in quantum statistical mechanics [PDF]

open access: yesCommunications in Mathematical Physics, 1973
It is shown that the infinite volume limit of the equilibrium reduced density matrices, shown by Ginibre to exist at low densities, satisfy the quantum time independent BBGKY hierarchy of equations. This extends analogous results for classical systems due to Gallavotti.

Monotonic converging variational approximations to the functional integrals in quantum statistical mechanics

open access: yes, 1975
We show, by making use of the functional integral technique, that, for a large class of useful quantum statistical systems, the partition function is, with respect to the coupling constant, the Laplace transform of a positive measure.

The Entropy-Based Quantum Metric

open access: yesEntropy, 2014
The von Neumann entropy S( D ^ ) generates in the space of quantum density matrices  D ^ the Riemannian metric ds2 = −d2S( D ^ ), which is physically founded and which characterises the amount of quantum information lost by mixing  D ...

Deformation quantization: Quantum mechanics lives and works in phase space

open access: yesEPJ Web of Conferences, 2014
Wigner’s 1932 quasi-probability Distribution Function in phase-space, his first paper in English, is a special (Weyl) representation of the density matrix.

Asymmetric Information and Quantization in Financial Economics

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2012
We show how a quantum formulation of financial economics can be derived from asymmetries with respect to Fisher information. Our approach leverages statistical derivations of quantum mechanics which provide a natural basis for interpreting quantum ...
