Research topics
My research is discussed under following research
categories, along with links to all my publications. The categories appear
roughly in reverse chronological order of the papers under them. Some papers
appear in more than one category. Review and pedagogical articles are in marked
with a .
Paper titles are linked to PDF files containing the complete text and figures.
A list of all publications is available. A list of almost all papers since April 1992 is also at the condmat archive. Among these, is
the very first paper on the
condmat archive.
