A Dilemma for Relational Quantum Mechanics
Principia: An International Journal of EpistemologyRelational quantum mechanics (RQM) is an interesting alternative to the standard responses to the measurement problem in quantum mechanics. But it suffers from a distinctive kind of epistemic solipsism: an observer can’t in principle know anything ...

The measurement problem in Quantum Mechanics: Convivial Solipsism [PDF]
EPJ Web of Conferences, 2020 The problem of measurement is often considered an inconsistency inside the quantum formalism. Many attempts to solve (or to dissolve) it have been made since the inception of quantum mechanics.

Quantum reference frames for general symmetry groups [PDF]
Quantum, 2020 A fully relational quantum theory necessarily requires an account of changes of quantum reference frames, where quantum reference frames are quantum systems relative to which other systems are described.

Quantization of events in the event-universe and the emergence of quantum mechanics
Scientific Reports, 2023 Quantum mechanics (QM) is derived based on a universe composed solely of events, for example, outcomes of observables. Such an event universe is represented by a dendrogram (a finite tree) and in the limit of infinitely many events by the p-adic tree ...

Equivalence of Approaches to Relational Quantum Dynamics in Relativistic Settings
Frontiers in Physics, 2021 We have previously shown that three approaches to relational quantum dynamics—relational Dirac observables, the Page-Wootters formalism and quantum deparametrizations—are equivalent.

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 ...

Relational Quantum Mechanics [PDF]
International Journal of Theoretical Physics, 1996 I suggest that the common unease with taking quantum mechanics as a fundamental description of nature (the "measurement problem") could derive from the use of an incorrect notion, as the unease with the Lorentz transformations before Einstein derived from the notion of observer-independent time.

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.

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.
