Epistemic Horizons From Deterministic Laws: Lessons From a Nomic Toy Theory
Johannes Fankhauser, Tomáš Gonda, Gemma De les Coves
Quantum theory has an epistemic horizon, i.e. exact values cannot be assigned simultaneously to incompatible physical quantities. As shown by Spekkens' toy theory, positing an epis…

An Invitation to Universality in Physics, Computer Science, and Beyond
Tomáš Gonda, Gemma De les Coves
A universal Turing machine is a powerful concept - a single device can compute any function that is computable. A universal spin model, similarly, is a class of physical systems wh…

A Framework for Universality in Physics, Computer Science, and Beyond
Tomáš Gonda, Tobias Reinhart, Sebastian Stengele +1
Turing machines and spin models share a notion of universality according to which some simulate all others. Is there a theory of universality that captures this notion? We set up a…
