De meningen ge-uit door medewerkers en studenten van de TU Delft en de commentaren die zijn gegeven reflecteren niet perse de mening(en) van de TU Delft. De TU Delft is dan ook niet verantwoordelijk voor de inhoud van hetgeen op de TU Delft weblogs zichtbaar is. Wel vindt de TU Delft het belangrijk - en ook waarde toevoegend - dat medewerkers en studenten op deze, door de TU Delft gefaciliteerde, omgeving hun mening kunnen geven.

Tomohiro Yokoyama

has left us for further post-doc career in Japan. He stayed with me as a post-doc – eventually, a JSPS fellow, from 6.4.2014. We have worked on Andreev bound states in superconducting heterostructures, with and without spin-orbit interaction. We still have to finish a (very big) paper. Thank you, Tomohiro, with you I did the stuff I wouldn’t do otherwise. Best luck with your new job!

On blogging in general :)

I cannot blog on time. I cannot stop blogging at all: I have a feeling, most likely irrational , that the life passes by without a trace if I don’t do this. To balance between this, I’d like to use a rather dirty trick of back-dating. Please do not be surprised.

First lecture Advanced Quantum Mechanics: 2016

This year I got a very convenient lecture room, zaal E, that can house almost an infinite number of students and has a slanted floor. I gave the same course in this room yet 10 years ago. It took a bit of time to adjust: and I could enjoy again. An inconvenience is that the lectures take place on early Monday morning :(

Despite this, the audience was full – not unusual for the first lecture. I took time explaining the rules of the course (those I myself find rather complex). Not that I felt understood, but I said what I had to. The stuff went rather fast. Nobody has heard of Heisenberg picture, no single hand – all right, but with this it went only faster. Still I was very vague about qubits and had to skip the harmonic oscillator – too much time lost in the beginning.

I had like 4 minutes for density matrix – no preliminary knowledge as well. Looked enough, but I have discovered that the outlining of the partial trace is too abstract to be taught that quickly …

Fortunately, there was enough time on Thursday. The presentations were fine, including density matrix from thermodynamical point of view. And I told about partial trace, slowly and with details – that seemed to go into open ears. Fine!
