Some new results on the Chu duality of discrete groups
Salvador Hernández, Ta-Sun Wu
This paper deals mainly with the Chu duality of discrete groups. Among other results, we give sufficient conditions for an group to satisfy Chu duality and characterize when t…
Magnetic field dependence of hole levels in self-assembled InAs quantum dots
J. I. Climente, J. Planelles, M. Pi +1
Recent magneto-transport experiments of holes in InGaAs quantum dots [D. Reuter, P. Kailuweit, A.D. Wieck, U. Zeitler, O. Wibbelhoff, C. Meier, A. Lorke, and J.C. Maan, Phys. Rev.…
Aharonov-Bohm effect for pedestrian
J. Planelles, J. I. Climente, J. L. Movilla
When a magnetic field pierces a multiple-connected quantum system, the corresponding wavefunction is altered although no net Lorentz force acts upon its carriers. This is the so ca…
Simple tangential families and perestroikas of their envelopes
Gianmarco Capitanio
Tangential families are 1-parameter families of rays emanating tangentially from smooth curves. We classify tangential family germs up to Left-Right equivalence: we prove that ther…
