Resumen
Concepts of basic electromagnetic theory In the Demonstration it is possible to choose whether to plot the charge's weak value, D2<Q2>S1(in units of the electron charge), as a function of the voltage bias (measured in μV), the phase difference, or the temperature (measured in mK). (The phase difference includes the Aharonov–Bohm flux and the phases of the transmission coefficients of both the quantum point contacts.) In all cases it is possible to control the other parameters, including the transparencies of both the quantum point contacts and the duration of the measurement (measured in nsec). In the upper panel of the Demonstration we also plot the upper bound for standard quantum average of the charge in arm 2 (the lower bound is obviously 0): the weak value is clearly beyond the marked bounds Componente Curricular::Educação Superior::Ciências Exatas e da Terra::Física
