On the Relativity of Quantumness as Implied by Relativity of Arithmetic and Probability

open access: yesEntropy
A hierarchical structure of isomorphic arithmetics is defined by a bijection gR:R→R. It entails a hierarchy of probabilistic models, with probabilities pk=gk(p), where g is the restriction of gR to the interval [0,1], gk is the kth iterate of g, and k is

The hidden economy in Jordan: A MIMIC approach

open access: yesCogent Economics & Finance, 2022
This paper uses the Multiple Indicators Multiple Causes (MIMIC) approach to determine the annual size and growth of the hidden economy in Jordan for the period 1980–2018.

Causally Informative Entropic Inequalities within Families of Distributions with Shared Marginals

open access: yesEntropy
The joint probability distribution of observable variables from a system is constrained by the underlying causal structure. In the presence of hidden variables, untestable independencies that involve hidden variables lead to testable causally-imposed ...

Hidden Variables or Positive Probabilities?

open access: yes, 2001
Despite claims that Bell's inequalities are based on the Einstein locality condition, or equivalent, all derivations make an identical mathematical assumption: that local hidden-variable theories produce a set of positive-definite probabilities for ...

Hidden Variables in Quantum Mechanics from the Perspective of Boltzmannian Statistical Mechanics

open access: yesQuantum Reports
This paper examines no-hidden-variables theorems in quantum mechanics from the point of view of statistical mechanics. It presents a general analysis of the measurement process in the Boltzmannian framework that leads to a characterization of (in ...

Historical and interpretative aspects of quantum mechanics: a physicists' naive approach

open access: yesCondensed Matter Physics, 2006
Many theoretical predictions derived from quantum mechanics have been confirmed experimentally for the last 80 years. However, interpretative aspects have long been subject to debate. Among them, the question of the existence of hidden variables is still

Hidden Variables in Bipartite Networks

open access: yes, 2011
We introduce and study random bipartite networks with hidden variables. Nodes in these networks are characterized by hidden variables which control the appearance of links between node pairs.

Local Hidden Variables Underpinning of Entanglement and Teleportation [PDF]

open access: yes, 2006
Entangled states whose Wigner functions are non-negative may be viewed as being accounted for by local hidden variables (LHV). Recently, there were studies of Bell's inequality violation (BIQV) for such states in conjunction with the well known theorem ...

No-hidden-variables proof for two spin-1/2 particles preselected and postselected in unentangled states [PDF]

open access: yes, 1997
It is a well-known fact that all the statistical predictions of quantum mechanics on the state of any physical system represented by a two-dimensional Hilbert space can always be duplicated by a noncontextual hidden-variables model. In this paper, I show
