Giant current fluctuations

in an overheated single electron transistor is a study which I’ve done with Matti Laakso and Tero Heikkila from Helsinki. The highlight of the research is that the distribution of the current may become a power-law, that makes it quite distinct from usual distributions.

Power-law distributions are rare in physics. It is third time in my life I encounter one. First time it was yet at university. I’ve read and memorized that the distribution of radiative losses by a fast charged particle in a media has a power-law tail. That formally renders the radiative losses unmeasurable (control question: explain why). With this piece of knowledge, I’ve managed to pass an examination I was totally unprepared for. Was a fun to use the trick once again.
