Directly computing Wigner functions for open quantum systems

Nick Huggett, Christian Käding, Mario Pitschmann +1

The Wigner function is a well-known phase space distribution function with many applications in quantum mechanics. In this article, we consider an open quantum system consisting of…

Is string field theory background independent?

Bhanu Narra, James Read, Matěj Krátký

String field theory is supposed to stand to perturbative string theory as quantum field theory stands to single-particle quantum theory; as such, it purports to offer a substantial…

Gravitational redshift revisited: inertia, geometry, and charge

Johannes Fankhauser, James Read

Gravitational redshift effects undoubtedly exist; moreover, the experimental setups which confirm the existence of these effects-the most famous of which being the Pound-Rebka expe…

On functional freedom and Penrose's critiques of string theory

Matěj Krátký, James Read

In his The Road to Reality as well as in his Fashion, Faith and Fantasy, Roger Penrose criticises string theory and its practitioners from a variety of angles ranging from conceptu…

Affine connections for Galilean and Carrollian structures: a unified perspective

Quentin Vigneron, Hamed Barzegar, James Read

We develop a classification of general Carrollian structures, permitting affine connections with both torsion and non-metricity. We compare with a recent classification of general…
