Fundamental time asymmetry from nontrivial space topology
F. R. Klinkhamer
It is argued that a fundamental time asymmetry could arise from the global structure of the space manifold. The proposed mechanism relies on the CPT anomaly of certain chiral gauge…
New analytic results for electroweak baryon number violation
F. R. Klinkhamer, Y. J. Lee
Real-time anomalous fermion number violation has been investigated for massless chiral fermions in spherically symmetric SU(2) Yang-Mills gauge field backgrounds which can be weakl…
CPT violation: mechanism and phenomenology
F. R. Klinkhamer
A new mechanism for T and CPT violation is reviewed, which relies on chiral fermions, gauge interactions and nontrivial spacetime topology. Also discussed are the possible effects…
Causality and radiatively induced CPT violation
C. Adam, F. R. Klinkhamer
We consider quantum electrodynamics with an additional Lorentz- and CPT-violating axial-vector term in the fermionic sector and discuss the possibility that radiative corrections i…
Torsion, topology and CPT anomaly in two-dimensional chiral U(1) gauge theory
F. R. Klinkhamer, C. Mayer
We consider the CPT anomaly of two-dimensional chiral U(1) gauge theory on a torus with topologically nontrivial zweibeins corresponding to the presence of spacetime torsion. The r…
Spectral flow of chiral fermions in nondissipative Yang-Mills gauge field backgrounds
F. R. Klinkhamer, Y. J. Lee
Real-time anomalous fermion number violation is investigated for massless chiral fermions in spherically symmetric SU(2) Yang-Mills gauge field backgrounds which can be weakly diss…
