Force balance in thermal quantum many-body systems from Noether's theorem
Sophie Hermann, Matthias Schmidt
We address the consequences of invariance properties of the free energy of spatially inhomogeneous quantum many-body systems. We consider a specific position-dependent transformati…
Quasicharacters, recoupling calculus and costratifications of lattice quantum gauge theory
P. D. Jarvis, G. Rudolph, M. Schmidt
We study the algebra of invariant representative functions over the N-fold Cartesian product of copies of a compact Lie group G modulo the action of conjugation by the diagonal sub…
Deformation quantization and homological reduction of a lattice gauge model
Markus J. Pflaum, Gerd Rudolph, Matthias Schmidt
For a compact Lie group we consider a lattice gauge model given by the -Hamiltonian system which consists of the cotangent bundle of a power of with its canonical symple…
Stratified structure of the observable algebra of Hamiltonian lattice gauge theory
Sebastian Knappe, Gerd Rudolph, Matthias Schmidt
We consider Kaehler quantized models whose underlying classical phase space has a stratified structure induced from the Hamiltonian action of a compact Lie group. We show how to im…
The Hilbert space costratification for the orbit type strata of SU(2)-lattice gauge theory
Erik Fuchs, Peter D Jarvis, Gerd Rudolph +1
We construct the Hilbert space costratification of -quantum gauge theory on a finite spatial lattice in the Hamiltonian approach. We build on previous work where…
Defining relations for the orbit type strata of SU(2)-lattice gauge models
Florian Fuerstenberg, Gerd Rudolph, Matthias Schmidt
We consider an SU(2)-lattice gauge model in the tree gauge. Classically, this is a system with symmetries whose configuration space is a direct product of copies of SU(2), acted up…
