Modeling the Arrows of Time with Causal Multibaker Maps
EntropyWhy do we remember the past, and plan the future? We introduce a toy model in which to investigate emergent time asymmetries: the causal multibaker maps. These are reversible discrete-time dynamical systems with configurable causal interactions. Imposing

On causality and superluminal behavior in classical field theories. Applications to k-essence theories and MOND-like theories of gravity [PDF]
, 2006 Field theories whose full action is Lorentz invariant (or diffeomorphism invariant) can exhibit superluminal behaviors through the breaking of local Lorentz invariance. Quantum induced superluminal velocities are well-known examples of this effect.

J.S. Bell's Concept of Local Causality
, 2011 John Stewart Bell's famous 1964 theorem is widely regarded as one of the most important developments in the foundations of physics. It has even been described as "the most profound discovery of science." Yet even as we approach the 50th anniversary of ...

Causality between challenges, availability, and extent of use of local building materials
South African Journal of Science, 2022 The promotion of sustainable practice in construction has resulted in a renewed focus on local building materials (LBMs). However, existing studies have not provided an extensive understanding of the challenges in the use and awareness of the ...

Quantum geometry with intrinsic local causality
, 1997 The space of states and operators for a large class of background independent theories of quantum spacetime dynamics is defined. The SU(2) spin networks of quantum general relativity are replaced by labelled compact two-dimensional surfaces. The space of

Macroscopically local correlations can violate information causality
, 2010 Although quantum mechanics is a very successful theory, its foundations are still a subject of intense debate. One of the main problems is the fact that quantum mechanics is based on abstract mathematical axioms, rather than on physical principles ...

Cones and causal structures on topological and differentiable manifolds [PDF]
, 1999 General definitions for causal structures on manifolds of dimension d+1>2 are presented for the topological category and for any differentiable one.

Bell's local causality is a d-separation criterion
, 2019 This paper aims to motivate Bell's notion of local causality by means of Bayesian networks. In a locally causal theory any superluminal correlation should be screened off by atomic events localized in any so-called \textit{shielder-off region} in the ...

Gravitational causality and the self-stress of photons
Journal of High Energy Physics, 2022 We study causality in gravitational systems beyond the classical limit. Using on-shell methods, we consider the 1-loop corrections from charged particles to the photon energy-momentum tensor — the self-stress — that controls the quantum interaction ...

Information causality from an entropic and a probabilistic perspective
, 2011 The information causality principle is a generalisation of the no-signalling principle which implies some of the known restrictions on quantum correlations.
