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…
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…
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…
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…
