Rotational invariance and the Pauli exclusion principle
In this article, the rotational invariance of entangled quantum states is investigated as a possible cause of the Pauli exclusion principle. First, it is shown that a certain class of rotationally invariant states can only occur in pairs. This will be referred to as the coupling principle. This in turn suggests a natural classification of quantum systems into those containing coupled states and...
متن کاملExperimental test of the Pauli Exclusion Principle
A short review is given of three experimental works on tests of the Pauli Exclusion Principle (PEP) in which the author has been involved during the last 10 years. In the first work a search for anomalous carbon atoms was done and a limit on the existence of such atoms was determined, C̃/C< 2.5×10. In the second work PEP was tested with the NEMO-2 detector and the limits on the violation of PEP ...
متن کاملSearch for Pauli exclusion principle violating atomic transitions and electron decay with a p-type point contact germanium detector
A search for Pauli-exclusion-principle-violating Kα electron transitions was performed using 89.5 kg-d of data collected with a p-type point contact high-purity germanium detector operated at the Kimballton Underground Research Facility. A lower limit on the transition lifetime of 5.8 × 10 s at 90% C.L. was set by looking for a peak at 10.6 keV resulting from the X-ray and Auger electrons prese...
متن کاملMixture of composite-boson molecules and the Pauli exclusion principle
Molecules made of two fermionic atoms are “cobosons”—a contraction for “composite bosons.” These molecules “feel” each other not only through interactions between atoms, but also through the Pauli exclusion between their fermionic components. In order to point out the importance of this Pauli exclusion in cold atom physics, we have calculated here the energy change of N identical cobosonic mole...
متن کاملA Classical Manifestation of the Pauli Exclusion Principle
The occupied and unoccupied fermionic BPS quantum states of a type-IIA string stretched between a D6-brane and an orthogonal D2-brane are described in M-theory by two particular holomorphic curves embedded in a Kaluza–Klein monopole. The absence of multiply-occupied fermionic states — the Pauli exclusion principle — is manifested in Mtheory by the absence of any other holomorphic curves satisfy...
