On the relation between perspective-neutral, algebraic, and effective quantum reference frames
Julian De Vuyst, Philipp A. Hoehn, Artur Tsobanjan
The framework of internal quantum reference frames (QRFs) constitutes a universal toolset for dealing with symmetries in quantum theory and has led to new revelations in quantum gr…
An algebraic approach to the "frozen formalism" problem of time
Martin Bojowald, Artur Tsobanjan
The long-standing problem of time in canonical quantum gravity is the source of several conceptual and technical issues. Here, recent mathematical results are used to provide a con…
Algebraic properties of quantum reference frames: Does time fluctuate?
Martin Bojowald, Artur Tsobanjan
Quantum reference frames are expected to differ from classical reference frames because they have to implement typical quantum features such as fluctuations and correlations. Here,…
Quantization of dynamical symplectic reduction
Martin Bojowald, Artur Tsobanjan
A long-standing problem in quantum gravity and cosmology is the quantization of systems in which time evolution is generated by a constraint that must vanish on solutions. Here, an…
Semiclassical States on Lie Algebras
Artur Tsobanjan
The effective technique for analyzing representation-independent features of quantum systems based on the semiclassical approximation (developed elsewhere), has been successfully u…
Effective Casimir Conditions and Group Coherent States
Martin Bojowald, Artur Tsobanjan
Properties of group coherent states can be derived "effectively" without knowing full wave functions. The procedure is detailed in this article as an example of general methods for…
