Entropy, 2021 Causality follows the thermodynamic arrow of time, where the latter is defined by the direction of entropy increase. After a brief review of an earlier version of this article, rooted in classical mechanics, we give a quantum generalization of the ...

Testing causal quantum theory [PDF]
Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2018 Causal quantum theory assumes that measurements or collapses are well-defined physical processes, localized in space–time, and never give perfectly reliable outcomes and that the outcome of one measurement only influences the outcomes of others within its future light cone.

Observer-dependent locality of quantum events
New Journal of Physics, 2018 In general relativity, the causal structure between events is dynamical, but it is definite and observer-independent; events are point-like and the membership of an event A in the future or past light-cone of an event B is an observer-independent ...

Emergent Quantum Mechanics: David Bohm Centennial Perspectives
Entropy, 2019 Emergent quantum mechanics (EmQM) explores the possibility of an ontology for quantum mechanics. The resurgence of interest in realist approaches to quantum mechanics challenges the standard textbook view, which represents an operationalist approach. The

Bounding quantum correlations with indefinite causal order
New Journal of Physics, 2015 Causal inequalities are bounds on correlations obtained when operations take place in a causal sequence, i.e. in which the background time or definite causal structure pre-exists such that every operation is either in the future, in the past or space ...

Causal structure of interacting Weyl fermions in condensed matter systems
Nature Communications, 2023 The spacetime light cone is central to the definition of causality in the theory of relativity. Recently, links between relativistic and condensed matter physics have been uncovered, where relativistic particles can emerge as quasiparticles in the energy-

Quantum correlations with no causal order [PDF]
Nature Communications, 2012 The idea that events obey a definite causal order is deeply rooted in our understanding of the world and at the basis of the very notion of time. But where does causal order come from, and is it a necessary property of nature? We address these questions from the standpoint of quantum mechanics in a new framework for multipartite correlations which does

On Explaining Quantum Correlations: Causal vs. Non-Causal [PDF]
Entropy, 2021 At the basis of the problem of explaining non-local quantum correlations lies the tension between two factors: on the one hand, the natural interpretation of correlations as the manifestation of a causal relation; on the other, the resistance on the part of the physics underlying said correlations to adjust to the most essential features of a pre ...
