My name is Ingemar Bengtsson, and I have
been a lecturer at Fysikum in
Of course,
not all my papers are published.
With Karol Zyczkowski from Krakow
I have written a book on quantum mechanics, seen through our eyes. It was
published by Cambridge University Press in April 2006. You can still get it:
I occasionally try to write popular
science articles. They are all in Swedish:
If you want to hear me trying to explain gravity (på svenska), you can do it from home.
In the department I am a member of the "KOMKO" group, which includes the
(informal) Relativity group (it has
a little homepage of its own), as well as the group for Quantum Information and Quantum Optics. The latter
has a seminar every other Tuesday in A3:1003, at 11.00. See the seminar list.
My views on teaching happen to be identical to those of Fred Hoyle, as
expressed in " The Universe: Past and present reflections
" (Ann. Rev. Astr. Astrophys. 1982), so there is no need to repeat them here.
This academic year I teach Analytical mechanics and Electrodynamics I (in
English, since English speaking students are always welcome).
· Elektrodynamik I. The book for the course is no less than that of J. D. Jackson, 3d ed. The course program, including exercises, for 2013 is on the course homepage . (The lecture notes below have just a little to do with this course.)
· Analytisk mekanik. The official book is Goldstein, Poole och Safko: Classical
Mechanics, third edition.
This book is rather verbose, and in fact my course follows my own
lecture notes (see below). The program, including exercises,
for this year is here: Analytical Mechanics. You can see some old exams if you
like (there were bonus points for those who did their hand-in exercises): Exams.
Examples of lecture notes:
I enjoy
supervising Master's Theses and such things. Some recent ones include
"Maximization of the Wehrl entropy in finite dimensions" by Anna Baecklund,
"Limits and special symmetries of extremal black holes" by Helgi Freyr Runarsson,
"Trapped surfaces in 2+1 dimensions" by Emma Jakobsson,
“The convex hull of spin coherent states” by Muhammad Sadiq,
"Conformal compactification
and anti-de Sitter space" by Valentina Di Carlo, and
"Gleason's theorem" by Helena Granström. Recent Bachelor's
Theses are
"On the foundations of classical thermodynamics, and the Tolman-Ehrenfest effect" by
William Rupush, "The 3-sphere and the bicycling black rings event horizon" by David Andersson,
and "Entropiska krafter, speciellt hos gummi" by Helena Engström. See
here for the relativistic ones and here for the quantum ones. My
graduate students are Kate Blanchfield and Emma Jakobsson.
My Erdös number is 3. My Einstein number is 4. And one more thing. A quote from James Lovelock, which I
had occasion to think about, some time ago actually:
"Of all the prizes that come from surviving more than fifty years, the
best is the freedom to be eccentric."
