Relational Quantum Geometry
Shadi Ali Ahmad, Wissam Chemissany, Marc S. Klinger +1
A common feature of the extended phase space of gauge theory, the crossed product of quantum theory, and quantum reference frames (QRFs) is the adjoining of degrees of freedom foll…
Quantum Null Geometry and Gravity
Luca Ciambelli, Laurent Freidel, Robert G. Leigh
In this work, we demonstrate that quantizing gravity on a null hypersurface leads to the emergence of a CFT associated with each null ray. This result stems from the ultralocal nat…
Quantum Reference Frames from Top-Down Crossed Products
Shadi Ali Ahmad, Wissam Chemissany, Marc S. Klinger +1
All physical observations are made relative to a reference frame, which is a system in its own right. If the system of interest admits a group symmetry, the reference frame observi…
