Bloch oscillations strictly aren’t the fictitious “jumping back” in the BZ that happens when you hit the edge—they’re the position-space oscillation that happens when the momentum repeatedly wraps around. But you’ve got the idea. | |
Jul 9 at 17:52 | comment | added | Gotaquestion | Thanks, to make sure I understand it correctly, am I correct in saying that an Umklapp process will never occur unless two pseudo-particles interact? If that is the case, then the electric field will produce Bloch oscillations (assuming ideal lattice) when it reaches the BZ boundary unless it interacts with another pseudo-particle , is that right? | |
