Dzyaloshinskii-Moriya interactions in valence bond systems (2008)

Tovar, Mayra, Raman, Kumar S., Shtengel, Kirill

We investigate the effect of Dzyaloshinskii-Moriya interactions on the low temperature magnetic susceptibility for a system whose low energy physics is dominated by short-range valence bonds...

Topological phases and topological entropy of two-dimensional systems with finite correlation length (2007)

Papanikolaou, Stefanos, Raman, Kumar S., Fradkin, Eduardo

We elucidate the topological features of the entanglement entropy of a region in two dimensional quantum systems in a topological phase with a finite correlation length $\xi$. Firstly, we suggest...
