Information geometry in quantum field theory: lessons from simple examples. (arXiv:2001.02683v1 [hep-th]) 上午10:07 | Johanna Erdmenger, Kevin T. Grosvenor, Ro Jefferson | quant-ph updates on arXiv.org Motivated by the increasing connections between information theory and high-energy physics, particularly in the context of the AdS/CFT correspondence, we explore the information geometry associated to a variety of simple systems. By studying their… Read more →

Gravitation in terms of observables. (arXiv:1802.02661v1 [gr-qc])  hep-th updates on arXiv.org on 2018-2-10 12:53am GMT Authors: Rodolfo Gambini, Jorge Pullin In the 1960’s, Mandelstam proposed a new approach to gauge theories and gravity based on loops. The program for gauge theories was completed for Yang–Mills theories by Gambini and Trias in the 1980’s. Gauge theories could be understood as representations of certain… Read more →

Classical Branch Structure from Spatial Redundancy in a Many-Body Wave Function  PRL: General Physics: Statistical and Quantum Mechanics, Quantum Information, etc. on 2017-3-24 2:00pm GMT Author(s): C. Jess Riedel When the wave function of a large quantum system unitarily evolves away from a low-entropy initial state, there is strong circumstantial evidence it develops “branches”: a decomposition into orthogonal components that… Read more →
