Quantum diffusion of electromagnetic fields of ultrarelativistic spin
... that at later time the magnetic field changes sign. We have observed this effect before for a scalar particle [30], where it is, in fact, much more prominent. We will add a few more comments about the sign flip later in this section. In Fig. 2 we plot each of the lines shown in Fig. 1 (left panel) s ...

What Every Physicist Should Know About String Theory
... Even though we do not really understand it, quantum gravity is supposed to be some sort of theory in which, at least from a macroscopic point of view, we average, in a quantum mechanical sense, over all possible spacetime geometries. (We do not know to what extent this description is valid microsco ...
