Representation Lost: The Case for a Relational Interpretation of Quantum Mechanics

Entropy, 2018
Contemporary non-representationalist interpretations of the quantum state (especially QBism, neo-Copenhagen views, and the relational interpretation) maintain that quantum states codify observer-relative information.

Heterogeneous relational message passing networks for molecular dynamics simulations

npj Computational Materials, 2022
With many frameworks based on message passing neural networks proposed to predict molecular and bulk properties, machine learning methods have tremendously shifted the paradigms of computational sciences underpinning physics, material science, chemistry,

Relational EPR

, 2006
We study the EPR-type correlations from the perspective of the relational interpretation of quantum mechanics. We argue that these correlations do not entail any form of 'non-locality', when viewed in the context of this interpretation.

Entropy Balance in the Expanding Universe: A Novel Perspective

Entropy, 2019
We describe cosmic expansion as correlated with the standpoints of local observers’ co-moving horizons. In keeping with relational quantum mechanics, which claims that quantum systems are only meaningful in the context of measurements, we suggest ...

Relational evolution of the degrees of freedom of generally covariant quantum theories [PDF]

, 2001
We study the classical and quantum dynamics of generally covariant theories with vanishing a Hamiltonian and with a finite number of degrees of freedom. In particular, the geometric meaning of the full solution of the relational evolution of the degrees ...

An Attempt to Understand Relational Quantum Mechanics

International Journal of Theoretical Physics, 2023
AbstractWe search for a possible mathematical formulation of some of the key ideas of the relational interpretation of quantum mechanics and study their consequences. We also briefly overview some proposals of relational quantum mechanics for an axiomatic reconstruction of the Hilbert space formulation of quantum mechanics.

On Ontological Alternatives to Bohmian Mechanics

Entropy, 2018
The article describes an interpretation of the mathematical formalism of standard quantum mechanics in terms of relations. In particular, the wave function ψ(x) is interpreted as a complex-valued relation between an entity (often called &ldquo ...

Quantum reference frames and deformed symmetries [PDF]

, 2007
In the context of constrained quantum mechanics, reference systems are used to construct relational observables that are invariant under the action of the symmetry group.

Hierarchical Language Models for Semantic Navigation and Manipulation in an Aerial‐Ground Robotic System

Advanced Intelligent Systems, EarlyView.
A hierarchical multimodal framework coupling a large language model for task decomposition and semantic mapping with a fine‐tuned vision‐language model for semantic perception, enhanced by GridMask, is presented. An aerial‐ground robot team exploits the semantic map for global and local planning.

Towards Relational Foundations for Spacetime Quantum Physics

Universe
Rovelli’s relational interpretation of quantum mechanics tells us that the description of a system in the formalism of quantum mechanics is not an absolute but is relative to the observer itself.
