Efeito Aharonov-Bohm: extensões auto-adjuntas e espalhamento
(Universidade Federal de São Carlos, 2009-10-05)
In this work we present a study of topics related to the Aharonov-Bohm (AB) e®ect. Our framework is that of nonrelativistic quantum mechanics and we use the point of view of mathematical physics. (1) We study the solenoid ...
Estabilidade dinâmica para sistemas quânticos dependentes do tempo
(Universidade Federal de São Carlos, 2006-10-16)
We study if a time-dependent system is either dynamically stable or unstable,
i.e., if the expected value of a positive and discrete observable is a bounded
function of time or not. Initially we consider topological ...
