Quantum Chains of Hopf Algebras with Quantum Double Cosymmetry
Florian Nill, Kornel Szlachanyi
Given a finite dimensional C^*-Hopf algebra H and its dual H^ we construct the infinite crossed product A=... x H x H^ x H ... and study its superselection sectors in the framework…
Large-Order Behavior of Two-coupling Constant -Theory with Cubic Anisotropy
H. Kleinert, S. Thoms
For the anisotropic $[u (\sum_{i=1^N ϕ_i^2)^2+v \sum_{i=1^N ϕ_i^4]$-theory with {} we calculate the imaginary parts of the renormalization-group functions in the form of a s…
Quantum Chains of Hopf Algebras with Order-Disorder Fields and Quantum Double Symmetry
Florian Nill, Kornel Szlachanyi
Given a finite dimensional C-*-Hopf algebra H and its dual H^ we construct the infinite crossed product A=... x H x H^ x H x ... and study its representations. A is the observable…
Variational Calculation of Effective Classical Potential at to Higher Orders
H. Kleinert, H. Meyer
Using the new variational approach proposed recently for a systematic improvement of the locally harmonic Feynman-Kleinert approximation to path integrals we calculate the partitio…
Precise variational tunneling rates for anharmonic oscillator with g<0
R. Karrlein, H. Kleinert
We systematically improve the recent variational calculation of the imaginary part of the ground state energy of the quartic anharmonic oscillator. The results are extremely accura…
Path Integral of Relativistic Coulomb System
H. Kleinert
The path integral of the relativistic Coulomb system is solved, and the wave functions are extracted from the resulting amplitude.
Five-loop renormalization group functions of -symmetric -theory and $\ep$-expansions of critical exponents up to $\ep^5$
H. Kleinert, J. Neu, V. Schulte-Frohlinde +2
Motivated by the discovery of errors in six of the 135 diagrams in the published five-loop expansions of the -function and the anomalous dimensions of the -symmetric $ϕ^…
Motion of a Rigid Body in Body-Fixed Coordinate System -- for Autoparrallel Trajectories in Spaces with Torsion
P. Fiziev, H. Kleinert
We use a recently developed action principle in spaces with curvature and torsion to derive the Euler equations of motion for a rigid body within the body-fixed coordinate system.…
New Action Principle for Classical Particle Trajectories in Spaces with Torsion
P. Fiziev, H. Kleinert
To comply with recent developments of path integrals in spaces with curvature and torsion we find the correct variational principle for the classical trajectories. Although the act…
Braid Relations in Affine Toda Field Theory
A. Fring
We provide explicit realizations for the operators which when exchanged give rise to the scattering matrix. For affine Toda field theory we present two alternative constructions, o…
