Manipulating and Measuring the Quantum State of Photons and Atoms
... rough msmt of a given rate first and then deciding how long to acquire data on that point. (b) Could also measure populations first, and then avoid wasting time on coherences which would close to 0. (c) Even if r has only a few significant eigenvalues, is there a way to quickly figure out in which b ...

Spin and orbital Kondo effect in electrostatically coupled quantum dots S. L
... Reversing the spin polarization of conductance can be induced either by a change in gate voltage or by reversing the magnetic field (Fig. 4). For g1 = –g2, an antisymmetric change in polarization is evident (bipolar spin filter). The four high-conductance lines visible in Fig. 3a occur in regions wh ...

... Electric forces can sometime be used to solve problems with Newton’s laws. But it is not usually possible to use constant acceleration kinematics as the field and force usually vary with distance. One exception is with charged plates which create constant fields and constant forces over reasonable d ...
