Local Scale Covariance and Its Radical Implications for Cosmology
Galaxies, 2021 Local scale covariance posits that no privileged length scales should appear in the fundamental equations of local, Minkowskian physics—why should nature have scale, but not position preferences?—yet, they clearly do.

Depicting qudit quantum mechanics and mutually unbiased qudit theories [PDF]
Electronic Proceedings in Theoretical Computer Science, 2014 We generalize the ZX calculus to quantum systems of dimension higher than two. The resulting calculus is sound and universal for quantum mechanics. We define the notion of a mutually unbiased qudit theory and study two particular instances of these ...

Simulating single-spin dynamics on an IBM five-qubit chip [PDF]
Revista Brasileira de Ensino de Física, 2020 In this paper we show how the IBM superconducting chips can be a powerful tool for teaching foundations of quantum mechanics for undergraduate students (for graduates as well, in some cases). To this end, we briefly discuss about the main elements of the

Interpretation of Quantum Theory: The Quantum “Grue-Bleen” Problem
Entropy, 2022 We present a critique of the many-world interpretation of quantum mechanics, based on different “pictures” that describe the time evolution of an isolated quantum system. Without an externally imposed frame to restrict these possible pictures, the theory

On the Stochastic Mechanics Foundation of Quantum Mechanics
Universe, 2021 Among the famous formulations of quantum mechanics, the stochastic picture developed since the middle of the last century remains one of the less known ones.

Geometric Event-Based Quantum Mechanics
New Journal of Physics, 2023 We propose a special relativistic framework for quantum mechanics. It is based on introducing a Hilbert space for events. Events are taken as primitive notions (as customary in relativity), whereas quantum systems (e.g. fields and particles) are emergent

Generalized uncertainty principle and burning stars
Frontiers in Astronomy and Space Sciences, 2022 Gamow’s theory of the implications of quantum tunneling for star burning has two cornerstones: quantum mechanics and the equipartition theorem. It has been proposed that both of these foundations are affected by the existence of a non-zero minimum length,

Quantum Theory, Namely the Pure and Reversible Theory of Information
Entropy, 2012 After more than a century since its birth, Quantum Theory still eludes our understanding. If asked to describe it, we have to resort to abstract and ad hoc principles about complex Hilbert spaces.
