Dinâmica e ruído quântico em osciladores paramétricos óticos com momento angular orbital
| Posted on: 06 mar. 2009We shall present a description of beams bearing orbital angular momentum (OAM)in the paraxial regime, in addition to techniques showing how to produce such beams. Followed by a brief classical description of the optical ... -
Fases geométricas e emaranhamento em sistemas quânticos de spins
| Posted on: 01 jan. 2011Geometric phases are associated with the description of many phenomena in quantum mechanics. The aim of this thesis is to analyze geometric phases in quantum spin chains and relate their behavior to the entanglement dynamics ...
