Canonical Clock Sectors and Relational Frame Equivalence in Brans--Dicke Theory
Yaser Tavakoli, Jerzy Lewandowski
We investigate the equivalence of the Jordan and Einstein frames of the Brans--Dicke theory before and after relational deparametrization of the constrained Hamiltonian system. Alt…
Isolated horizons of the Hopf bundle structure transversal to the null direction, the horizon equations and embeddability in NUT-like spacetimes
Denis Dobkowski-Ryłko, Jerzy Lewandowski, Maciej Ossowski
Isolated horizons that admit the Hopf bundle structure are investigated, however the null direction is allowed not to be tangent to the bundle fibres. The geomet…
Emergence of Riemannian Quantum Geometry
Hal M. Haggard, Jerzy Lewandowski, Hanno Sahlmann
In this chapter we take up the quantum Riemannian geometry of a spatial slice of spacetime. While researchers are still facing the challenge of observing quantum gravity, there is…
Symplectic charges in the Yang-Mills theory of the normal conformal Cartan connection: applications to gravity
Adam Bac, Wojciech Kamiński, Jerzy Lewandowski +1
It is known that a source-free Yang-Mills theory with the normal conformal Cartan connection used as the gauge potential gives rise to equations of motion equivalent to the vanishi…
Scalar curvature operator for quantum-reduced loop gravity
Jerzy Lewandowski, Ilkka Mäkinen
In a previous article we have introduced an operator representing the three-dimensional scalar curvature in loop quantum gravity. In this article we examine the new curvature opera…
Quantum Oppenheimer-Snyder and Swiss Cheese models
Jerzy Lewandowski, Yongge Ma, Jinsong Yang +1
By considering the quantum Oppenheimer-Snyder model in loop quantum cosmology, a new quantum black hole model whose metric tensor is a suitably deformed Schwarzschild one is derive…
