Fluctuations of intensive quantities in statistical thermodynamics
Artur E. Ruuge
In phenomenological thermodynamics, the canonical coordinates of a physical system split in pairs with each pair consisting of an extensive quantity and an intensive one. In the pr…
Pauli problem in thermodynamics
Artur E. Ruuge
A thermodynamic analogue of the Pauli problem (reconstruction of a wavefunction from the position and momentum distributions) is formulated. The coordinates of a quantum system are…
New Examples of Kochen-Specker Type Configurations on Three Qubits
Artur E. Ruuge
A new example of a saturated Kochen-Specker (KS) type configuration of 64 rays in 8-dimensional space (the Hilbert space of a triple of qubits) is constructed. It is proven that th…
Microlagrangian manifolds and quasithermodynamic fluctuations of nonequilibrium states
Artur Ruuge
The paper deals with "quantization" and "second quantization" of phenomenological thermodynamics with respect to the Boltzmann's constant. It is suggested to perceive the quasither…
q-Legendre Transformation: Partition Functions and Quantization of the Boltzmann Constant
Artur E. Ruuge, Freddy van Oystaeyen
In this paper we construct a q-analogue of the Legendre transformation, where q is a matrix of formal variables defining the phase space braidings between the coordinates and momen…
Distortion of the Poisson Bracket by the Noncommutative Planck Constants
Artur E. Ruuge, Freddy van Oystaeyen
In this paper we introduce a kind of "noncommutative neighbourhood" of a semiclassical parameter corresponding to the Planck constant. This construction is defined as a certain fil…
Exceptional and Non-crystallographic Root Systems and the Kochen-Specker Theorem
Artur Ruuge
The Kochen-Specker theorem states that a 3-dimensional complex Euclidean space admits a finite configuration of projective lines such that the corresponding quantum observables (th…
Non-bicolourable Finite Configurations of Rays and Their Deformations
Artur Ruuge
A new infinite family of examples of finite non-bicolorable configurations of rays in Hilbert space is described. Such configurations appear in the analysis of quantum mechanics in…
New Families of Finite Coherent Orthoalgebras without Bivaluations
Artur Ruuge, Fred Van Oystaeyen
In the present paper we study the following problem: how to construct a coherent orthoalgebra which has only a finite number of elements, but at the same time does not admit a biva…
