Conductivity in a disordered one dimensional system of interacting fermions

It has been shown that even weak repulsive interaction between fermions destroys the Anderson localization due to disorder and leads to nonzero electrical conductivity at finite temperatures.

Dynamical central peak and spinon deconfinement in frustrated spin chains

It has been shown that the frustrated spin chain as modelled with the J1-J2 model exhibits anomalous dynamical correlations. With the novel FTD-DMRG method we establishe the existence of narrow central peak at nonzero temperature which is the consequence of spinon deconfinement.
