[hep-th] Ricard Sabo - kolokvijum na fakultetu

[Branislav Cvetkovic]

Postovane kolege,

U sredu 11. aprila u 11 h na Fizickom fakultetu Ricard Sabo (Univerzitet 
u Einburgu), predsedavajuci COST akcije "Quantum Structure of Spacetime 
(QSPACE)", ce odrzati kolokvijum pod naslovom  "Deformations of Quantum 
Theory".
U nastavku je apstrakt kolokvijuma.

Pozdrav Branislav

Abstract

Theoretical approaches to quantum gravity suggest that the conventional
notions of space and time become meaningless at ultra-short distance
scales. In many instances, dynamics in such ensuing "fuzzy" spacetimes 
can
be captured by certain deformations of quantum mechanics and quantum 
field
theory. In this lecture I will explain some of these deformed quantum
theories and how they may ultimately teach us something about quantum
gravity. I will explain how these theoretical consequences can connect 
to
real-world measurable quantities, and analyse in detail a simple
deformation of quantum mechanics which may be realised in a table-top
experiment. From the theoretical side, I will explain how these quantum
systems are related to the nonassociative algebras of observables 
proposed
in the beginnings of quantum mechanics and quantum field theory by 
Jordan,
von Neumann, Wigner and others to study the mathematical and conceptual
foundations of quantum theory.
