• Abstract: This article suggests that thinking about the role of reference frames can provide new insight into Extended Wigner's Friend scenarios. This involves appealing to symmetries to make a principled distinction between properties of a system which are meaningful only relative to an external reference system and properties which are meaningful without further relativization. Thus we may propose that there are always well-defined facts about what observers have observed, but there are not necessarily well-defined facts about the relations between their reference frames, so there will not always exist a joint distribution over their outcomes which can meaningfully be compared to the predictions of quantum mechanics. In addition, this approach also offers a general argument against the idea that there should be a regress of relativization.

• Rethinking Distance Metrics for Counterfactual Explainability [53.436414009687]
  We investigate a framing for counterfactual generation methods that considers counterfactuals not as independent draws from a region around the reference, but as jointly sampled with the reference from the underlying data distribution. We derive a distance metric, tailored for counterfactual similarity that can be applied to a broad range of settings.

• How do we Observe Relational Observables? [0.0]
  How do relational observables actually make contact with experience? I argue that this question can only be answered by providing a schematization of the observer. I consider what this means for the prospects of using quantum reference frames to address the problem of time.

• Relational Quantum Mechanics, Quantum Relativism, and the Iteration of Relativity [0.0]
  The idea that the dynamical properties of quantum systems are invariably relative to other systems has recently regained currency. Are there absolute facts about the properties one system possesses relative to a specified reference, or is this again a relative matter, and so on? I conclude with some reflections on the current state of play in perspectivist versions of RQM and quantum relativism more generally.

• Nonparametric Partial Disentanglement via Mechanism Sparsity: Sparse Actions, Interventions and Sparse Temporal Dependencies [58.179981892921056]
  This work introduces a novel principle for disentanglement we call mechanism sparsity regularization. We propose a representation learning method that induces disentanglement by simultaneously learning the latent factors. We show that the latent factors can be recovered by regularizing the learned causal graph to be sparse.

• Nonrelativistic spatiotemporal quantum reference frames [0.0]
  We introduce and analyze a nonrelativistic framework in which each system contains an internal clock in addition to its external clock. We show that even in simple scenarios, the relative uncertainty between clocks affects the relative spatial spread of the systems.

  We discuss some difficulties that arise in attempting to interpret the Page-Wootters and Internal Quantum Reference Frames formalisms. We argue that without a clear operational interpretation, such reference frames might not be suitable to define an equivalence principle.

• Quantum Relativity of Subsystems [58.720142291102135]
  We show that different reference frame perspectives induce different sets of subsystem observable algebras, which leads to a gauge-invariant, frame-dependent notion of subsystems and entanglement. Such a QRF perspective does not inherit the distinction between subsystems in terms of the corresponding tensor factorizability of the kinematical Hilbert space and observable algebra. Since the condition for this to occur is contingent on the choice of QRF, the notion of subsystem locality is frame-dependent.

• Localisation in quasiperiodic chains: a theory based on convergence of local propagators [68.8204255655161]
  We present a theory of localisation in quasiperiodic chains with nearest-neighbour hoppings, based on the convergence of local propagators. Analysing the convergence of these continued fractions, localisation or its absence can be determined, yielding in turn the critical points and mobility edges. Results are exemplified by analysing the theory for three quasiperiodic models covering a range of behaviour.
