Gauge Symmetry Breaking Lattice Regularizations and their Continuum Limit
Thorsten Lang, Susanne Schander
Lattice regularizations are pivotal in the non-perturbative quantization of gauge field theories. Wilson's proposal to employ group-valued link fields simplifies the regularization…
Quantum Geometrodynamics Revived II. Hilbert Space of Positive Definite Metrics
Thorsten Lang, Susanne Schander
This paper represents the second in a series of works aimed at reinvigorating the quantum geometrodynamics program. Our approach introduces a lattice regularization of the hypersur…
Quantum Geometrodynamics Revived I. Classical Constraint Algebra
Thorsten Lang, Susanne Schander
In this series of papers, we present a set of methods to revive quantum geometrodynamics which encountered numerous mathematical and conceptual challenges in its original form prom…
Backreaction in Cosmology
S. Schander, T. Thiemann
In this review, we investigate the question of backreaction in different approaches to cosmological perturbation theory, and with a special focus on quantum theoretical aspects. By…
Quantum Cosmological Backreactions IV: Constrained Quantum Cosmological Perturbation Theory
S. Schander, T. Thiemann
This is the fourth paper in a series of four in which we use space adiabatic methods in order to incorporate backreactions among the homogeneous and between the homogeneous and inh…
Quantum Cosmological Backreactions III: Deparametrised Quantum Cosmological Perturbation Theory
S. Schander, T. Thiemann
This is the third paper in a series of four in which we use space adiabatic methods in order to incorporate backreactions among the homogeneous and between the homogeneous and inho…
