Dmitry Podolsky has got his PhD from Landau Institute for Theoretical Physics. He currently works as postdoc at Case Western Reserve University. He is also one of the editors of NEQNET.

209. Gmail can now work offline

Sorry for the offtopic, but as I know, many of you (as well as myself, of course) currently use Gmail as their main email account. Is Gmail the most popular email platform among scientists? May very well be, support of conversations is too attractive I have no doubts that many times the fact that your [...]

Sorry for being quiet, has _so much_ exciting work to do # I’m a kind of back. Still overwhelmed by the amount of work to do, maybe will tweet a bit rarer for a couple of days. # If you ask me something, please don’t be upset if I’ll not reply immediately, I am kind [...]

207. Edward Farhi explains at Google why physicists need LHC

It’s great that Googlers are interested to hear talks by science experts, maybe it will help them to understand what is actually related to science and what is not Because right now the ads that AdSense serves to science related sites and blogs are terrible – to the degree they can be hardly called contextual [...]

206. A conference on black holes at PI

A very interesting conference organized by Rob Meyers, Herman Verlinde and Jaume Gomis takes place currently in PI. The topic of the conference is related to information loss in black holes and unitarity of quantum gravity in general (the one that I tried to discuss so unsuccessfully on the blog in December – I am [...]

203. Quantum Hall effect. One open question

I cannot finish discussing quantum Hall effect without explaining why, after all those years of study, Laughlin wavefunction and composite fermions, it still remains interesting for a condensed matter theorist. The reason is existence of the state with is a fully spin polarized FQHE state described by so called Moore-Read wavefunction. Some people also think [...]

200. That’s right – two hundred

And THIS… IS… (let me say that again) a post number 200! I cannot believe my own eyes – it seems that I celebrated the post number 100 just a couple of months ago! As you can see, NEQNET grows relatively slowly but it grows. What has changed the last month? Many things. First of [...]

198. Fractional quantum Hall effect – a few words about theory

Finally, after going through the integer quantum Hall effect, we are a kind of ready to discuss one of the biggest puzzles in condensed matter theory: the fractional quantum Hall effect. As you remember, it is also characterized by the quantization of the the Hall resistivity , (1) but the number in this formula acquires [...]
