Quantum phenomena in magnetic nano clusters

Quantum current modeling in nano-transistors with a quantum dot

Carbon quantum dots (CQDs) serve as a new class of ‘zero dimensional’ nanomaterial’s in thecarbon class with sizes below 10 nm. As light emitting nanocrystals, QDs are assembled from semiconductormaterials, from the elements in the periodic groups of II-VI, III-V or IV-VI, mainly thanks to impacts of quantum confinement QDs have unique optical properties such as brighter, highly pho...

Quantum phase interference and parity effects in magnetic molecular clusters

An experimental method based on the Landau-Zener model was developed to measure very small tunnel splittings in molecular clusters of eight iron atoms, which at low temperature behave like a nanomagnet with a spin ground state of S = 10. The observed oscillations of the tunnel splittings as a function of the magnetic field applied along the hard anisotropy axis are due to topological quantum in...

Non-thermal Phenomena in Galaxy Clusters

The recent evidences of the presence of magnetic fields and relativistic particles in galaxy clusters are reviewed. The existence of μG-level magnetic fields in cluster atmospheres appears well established from the detection of diffuse radio emission and from studies of Rotation Measure. The fact that the diffuse radio emission is not common in clusters favours the hypothesis that the populatio...
