Some of my research

Warning: This section is currently under construction.

I am interested in quantum phases of strongly correlated electron systems, quantum phase transitions between them and, in general, competition between classical and quantum ordering tendencies. Such a competition is the driving force behind complicated phase diagrams of many frustrated quantum magnets (such as kagome antiferromagnet on the right :)) -this constitutes one of my research topics. The other topic is also very interesting - transport properties of strongly correlated electrons, especially in low-dimensional geometry.

Here are two recent papers on spontaneously dimerized phases of frustrated quantum antiferromagnets:

The first deals with quasi-one-dimensional version of the square lattice antiferromagnet
[Phys. Rev. Lett. 93, 127202 (2004)] (PDF file)
The other is about pyrochlore antiferromagnet
[cond-mat/0503296; Phys. Rev. B 72, 094416 (2005)] (PDF file)

Simply my best project
