The (1+3)-dimensional 'quantum principle of relativity' is Einstein's principle of relativity
Matthew J. Lake
We show that the -dimensional `superboost' operators, proposed in Dragan and Ekert's most recent work on superluminal reference frames \cite{Dragan:2022txt}, are simply the…
Towards a group structure for superluminal velocity boosts
Matthew J. Lake
Canonical subluminal Lorentz boosts have a clear geometric interpretation. They can be neatly expressed as hyperbolic rotations, that leave both the family of -sheet hyperboloid…
Quantum reference frames, revisited
Matthew J. Lake, Marek Miller
The topic of quantum reference frames (QRFs) has attracted a great deal of attention in the recent literature. Potentially, the correct description of such frames is important for…
Dimensionally-dependent uncertainty relations, or why we (probably) won't see micro-black holes at the LHC, even if large extra dimensions exist
Matthew J. Lake, Shi-Dong Liang, Anucha Watcharapasorn
We present a simple gedanken experiment in which a compact object traverses a spacetime with three macroscopic spatial dimensions and compact dimensions. The compactification r…
Problems with Modified Commutators
Matthew J. Lake, A. Watcharapasorn
The purpose of this paper is to challenge the existing paradigm on which contemporary models of generalised uncertainty relations (GURs) are based, that is, the assumption of modif…
Generalised Uncertainty Relations from Finite-Accuracy Measurements
Matthew J. Lake, Marek Miller, Ray Ganardi +1
In this short note we show how the Generalised Uncertainty Principle (GUP) and the Extended Uncertainty Principle (EUP), two of the most common generalised uncertainty relations pr…
