The Pivotal Role of Causality in Local Quantum Physics [PDF]

open access: yesJournal of Physics A: Mathematical and General, 1998
In this article an attempt is made to present very recent conceptual and computational developments in QFT as new manifestations of old and well establihed physical principles.

Local Granger causality [PDF]

open access: yesPhysical Review E, 2021
Granger causality is a statistical notion of causal influence based on prediction via vector autoregression. For Gaussian variables it is equivalent to transfer entropy, an information-theoretic measure of time-directed information transfer between jointly dependent processes.

Causality and localization operators [PDF]

open access: yesPhysics Letters A, 2005
The evolution of the expectation values of one and two points scalar field operators and of positive localization operators, generated by an istantaneous point source is non local. Non locality is attributed either to zero point vacuum fluctuations, or to non local operations or to the microcausality principle being no satisfied.

Local Causal Discovery for Estimating Causal Effects

open access: yesCoRR, 2023
Even when the causal graph underlying our data is unknown, we can use observational data to narrow down the possible values that an average treatment effect (ATE) can take by (1) identifying the graph up to a Markov equivalence class; and (2) estimating that ATE for each graph in the class.

LOCALITY, CAUSALITY AND NONCOMMUTATIVE GEOMETRY [PDF]

open access: yesInternational Journal of Modern Physics A, 2006
We analyze the causality condition in noncommutative field theory and show that the nonlocality of noncommutative interaction leads to a modification of the light cone to the light wedge. This effect is generic for noncommutative geometry. We also check that the usual form of energy condition is violated and propose that a new form is needed in ...

Comment on “Bell’s Theorem Versus Local Realism in a Quaternionic Model of Physical Space”

open access: yesIEEE Access, 2021
In this paper, critical errors found in the paper “Bell’s theorem versus local realism in a quaternionic model of physical space,” by J. Christian, published in IEEE Access, are pointed out. The above paper, in fact, contains several

Simple and Instantaneous Causality in A Multivariate Auto-Regressive Models: An Application On Some Monetary Variables of the Egyptian Economy [PDF]

open access: yesMaǧallaẗ Al-Buḥūṯ Al-Mālīyyaẗ wa Al-Tiğāriyyaẗ, 2021
Granger`s (1969) concept and definitions of causality, feedback, and instantaneous causality and Akaike final prediction error criterion and extended by Chan et al (1982) to fit a multivariate autoregressive model are used.

Three principles leading to the bell inequalities [PDF]

open access: yesBelgrade Philosophical Annual, 2016
In the paper we compare three principles accounting for correlations, namely Reichenbach's Common Cause Principle, Bell's Local Causality Principle, and Einstein's Reality Criterion and relate them to the Bell inequalities.
