We consider the combined mean-field and semiclassical limit for a system of the N fermions interacting through singular potentials. We prove the uniformly in the Planck constant h propagation of quant...
A Simplified, Bohr Quantum Theoretical Derivation of the Unruh Temperature, Entropy, and Evaporation

In this work we reproduce Unruh temperature for a spherical physical system using a simplified rule, very similar to Bohr angular momentum quantization postulate interpreted via de Broglie relation, a...

Conventional quantum mechanics with a complex Hilbert space and the Born Rule is derived from five axioms describing properties of probability distributions for the outcome of measurements. Axioms I,...
Derivation of reduced two-dimensional fluid models via Dirac's theory of constrained Hamiltonian systems
two-dimensional fluid models Dirac's theory Hamiltonian systems
2010/4/1
We present a Hamiltonian derivation of a class of reduced plasma two-dimensional fluid models, an example being the Charney-Hasegawa-Mima equation. These models are obtained from the same parent Hamil...
Derivation of sensitivity of a Geiger mode APDs detector from a given efficiency for QKD experiments
Quantum Cryptography Detection sensitivity and efficiency
2010/4/7
The detection sensitivity (DS) of the commercial single-photon-receiver based on InGaAs gate-mode avalanche photodiode is estimated. Instalment of a digital-blanking-system (DBS) to reduce dark curren...
This paper deals with the foundations of quantum mechanics. We start by outlining the characterisation, due to Birkhoff and Von Neumann,of the logical structures of the theories of classical physics a...
