On the Geometry of the Berry-Robbins Approach to Spin-Statistics
A. F. Reyes-Lega, N. A. Papadopoulos
Within a geometric and algebraic framework, the structures which are related to the spin-statistics connection are discussed. A comparison with the Berry-Robbins approach is made.…
On the realization of Symmetries in Quantum Mechanics
Kai Johannes Keller, Nikolaos A. Papadopoulos, Andrés F. Reyes-Lega
The aim of this paper is to give a simple, geometric proof of Wigner's theorem on the realization of symmetries in quantum mechanics that clarifies its relation to projective geome…
The spin-statistics relation in nonrelativistic quantum mechanics and projective modules
N. A. Papadopoulos, M. Paschke, A. F. Reyes-Lega +1
In this work we consider non-relativistic quantum mechanics, obtained from a classical configuration space Q of indistinguishable particles. Following an approach proposed by one o…
Natural extensions of the Connes-Lott Model and comparison with the Marseille-Mainz Model
N. A. Papadopoulos, J. Plass
An extension of the Connes--Lott model is proposed. It is also within the framework of the A.Connes construction based on a generalized Dirac--Yukawa operator and the K--cycle $(H,…
TG-Equivariance of Connections and Gauge Transformations
H. M. Bosselmann, N. A. Papadopoulos
We consider the notion of a connection on a principal bundle from the point of view of the action of the tangential group . This leads to a new definition of a connect…
Models of Electroweak Interactions in Non-Commutative Geometry: A Comparison
N. A. Papadopoulos, J. Plass, F. Scheck
Alain Connes' construction of the standard model is based on a generalized Dirac-Yukawa operator and the K-cycle $(\HD ,D)$, with $\HD$ a fermionic Hilbert space. If this construct…
