# The Paradigm of Kinematics and Dynamics Must Yield to Causal Structure

@article{Spekkens2015ThePO, title={The Paradigm of Kinematics and Dynamics Must Yield to Causal Structure}, author={Robert W. Spekkens}, journal={arXiv: Quantum Physics}, year={2015}, pages={5-16} }

The distinction between a theory’s kinematics and its dynamics, that is, between the space of physical states it posits and its law of evolution, is central to the conceptual framework of many physicists. A change to the kinematics of a theory, however, can be compensated by a change to its dynamics without empirical consequence, which strongly suggests that these features of the theory, considered separately, cannot have physical significance. It must therefore be concluded (with apologies to…

The Babylonian conception and conventionalism about laws in physics

- Philosophy, Physics
- 2022

In this paper I discuss two features of laws in physics and ask to what extent these features are compatible with different philosophical accounts of laws of nature. These features are (i) that laws…

Spooky Action at a Temporal Distance

- PhilosophyEntropy
- 2018

The origins of the assumption of temporal locality are investigated, arguing that it has arisen for historical and pragmatic reasons rather than good scientific ones, then it is explained why temporal locality is in tension with relativity and some recent results which cast doubt on its validity.

Modeling observers as physical systems representing the world from within: Quantum theory as a physical and self-referential theory of inference

- Physics
- 2017

It is argued that the formalism of quantum theory can be derived from two related intuitive principles: inference is a physical process performed by physical systems, observers, which are part of the experimental setup and non-commutativity and imaginary-time quantum mechanics.

The ontological identity of empirical indiscernibles: Leibniz's methodological principle and its significance in the work of Einstein

- Philosophy

This article explores the following methodological principle for theory construction in physics: if an ontological theory predicts two scenarios that are ontologically distinct but empirically…

A Separable, Dynamically Local Ontological Model of Quantum Mechanics

- Physics
- 2015

This work finds that the resulting model violates local causality, but satisfies both separability and dynamical locality, making it a candidate for the ‘most local’ ontological model of quantum mechanics.

Operational quantum theory without predefined time

- Philosophy
- 2016

The standard formulation of quantum theory assumes a predefined notion of time. This is a major obstacle in the search for a quantum theory of gravity, where the causal structure of space-time is…

A Process Model of Non-Relativistic Quantum Mechanics

- Physics
- 2014

A process model of quantum mechanics utilizes a combinatorial game to generate a discrete and finite causal space I upon which can be defined a self-consistent quantum mechanics. An emergent…

The Operational Choi–Jamiołkowski Isomorphism

- PhilosophyEntropy
- 2020

An operational formulation of the Choi–Jamiołkowski isomorphism is used to explore an approach to quantum mechanics in which the state is not the fundamental object and demonstrates that there is no need to postulate states to be the bearers of these properties.

Colloquium
: Bell’s theorem and locally mediated reformulations of quantum mechanics

- Physics
- 2019

In this critical review of Bell's Theorem, its implications for reformulations of quantum theory are considered. The assumptions of the theorem are set out explicitly, within a framework of…

We just cannot have classical and quantum behavior at the same TIME

Frauchiger and Renner recently cast doubt on the universal applicability of Quantum Mechanics [1]. In the following, it is pointed out that their conclusion of one of three common-sense conditions,…

Unified dynamics for microscopic and macroscopic systems.

A modified quantum dynamics for the description of macroscopic objects is constructed and it is shown that it forbids the occurrence of linear superpositions of states localized in far-away spatial regions and induces an evolution agreeing with classical mechanics.

It is shown that for models wherein the quantum state has the status of something real, the failure of locality can be established through an argument considerably more straightforward than Bell’s theorem.
