First Principle Calculations of Positron
... • The state of the positron can be explained in terms of the positron Affinity (calculated by DFT GGA) between the Qdot and the matrix. • Potential well is about 2 eV therefore positrons are trapped in the CdSe Qdots. • Using an LMTO basis set we find that almost 80% of the positron wave function is ...

Limitations on the superposition principle: superselection

However, despite being fundamental, it is easy to realize that the superposition principle cannot hold unrestrictedly in every situation. For example, think of photons and el ...

... A good example of damping can be seen in the moving coil galvanometer. Electromagnetic damping is used here: the coil moves in a magnetic field and the current flowing in it can be shorted with a resistor, thus varying the damping. The system is either (i) dead beat — that is, critically damped, or ...
