Third Lecture Quantum Transport 2012
has hardly started yet, I have shown only 3-4 transparencies of this. The audience this year is very much listening, and posing interesting questions. I still have to learn how to respond to this without ruining the time schedule.
To give an example: we have been talking about the Aharonov-Bohm effect, quantum interference of an electron about a magnetic coil. That provoked a question: “Is the interference affected by the measurement of magnetic field in the coil?”. This is a splendid question that reflects most of physics like a water droplet reflects most of the Universe. I enjoyed answering, yet 20 minutes have gone…
