Non-inertial quantum clock frames lead to non-Hermitian dynamics
Communications Physics, 2022 Relativistic theories brought the operational notion of time to the center stage of physics. Here, the authors show that effective unitary dynamics is not guaranteed if this notion is extended to quantum mechanics when relativistic corrections are ...

Algebraic Properties of Quantum Reference Frames: Does Time Fluctuate?
Quantum Reports, 2022 Quantum reference frames are expected to differ from classical reference frames because they have to implement typical quantum features such as fluctuations and correlations.

What Ontology for Relational Quantum Mechanics?
Foundations of Physics, 2022 AbstractIn this paper, we evaluate some proposals that have been put forward to clarify the ontological consequences of relational quantum mechanics. We first focus on priority monism and ontic structural realism and argue that these views are not suitable for providing an ontological interpretation of the theory.

New Journal of Physics, 2022 We introduced with coauthors some years ago a solution to the problem of time in quantum gravity which consists in formulating the quantum theory in terms of real clocks.

An alternative formalism for modeling spin
European Physical Journal C: Particles and Fields, 2022 We present an alternative formalism for modeling spin. The ontological elements of this formalism are base-2 sequences of length n. The machinery necessary to model physics is then developed by considering correlations between base-2 sequences.

Epistemological vs. Ontological Relationalism in Quantum Mechanics: Relativism or Realism? [PDF]
, 2017 In this paper we investigate the history of relationalism and its present use in some interpretations of quantum mechanics. In the first part of this article we will provide a conceptual analysis of the relation between substantivalism, relationalism and

Switching Quantum Reference Frames for Quantum Measurement [PDF]
Quantum, 2020 Physical observation is made relative to a reference frame. A reference frame is essentially a quantum system given the universal validity of quantum mechanics. Thus, a quantum system must be described relative to a quantum reference frame (QRF). Further

Quantum Reports, 2023 In this work, an alternative attempt to motivate the Many-Worlds Interpretation (MWI) is undertaken. The usual way of arguing for MWI mostly revolves around how it might solve the measurement problem in a more straightforward and concise manner than ...

Relational quantum mechanics is still incompatible with quantum mechanics
European Journal for Philosophy of ScienceWe showed in a recent article (Lawrence et. al., 2023, Quantum 7, 1015), that relative facts (outcomes), a central concept in Relational Quantum Mechanics, are inconsistent with Quantum Mechanics. We proved this by constructing a Wigner-Friend type sequential measurement scenario on a Greenberger-Horne-Zeilinger (GHZ) state of three qubits, and making ...
