Caracterização magnética de compósitos multiferróicos particulados Pb(Zr0,52Ti0,48)O4/CoFe2O4
(Universidade Federal de São Carlos, 2014-08-26)
This work was studied the magnetic and electrical properties of particulate multiferroic composite Pb (Zr0,52Ti0,48) O4 / CoFe2O4 (PZT / CFO) (0-3 type) prepared by the polymeric method of Pechini and sintered by ultra-rapid ...
Termalização de qubits sujeitos à ação de reservatórios coletivos markovianos
(Universidade Federal de São Carlos, 2014-08-26)
We are interested in understanding the process of Markovian thermalization in quantum systems when we have one or two qubits interacting with a quantum electromagnetic field mode, using the Rabi model, in situations where ...
