Density Matrix Renormalization Group in the Heisenberg Picture
Michael J. Hartmann, Javier Prior, Stephen R. Clark +1
In some cases the state of a quantum system with a large number of subsystems can be approximated efficiently by the density matrix renormalization group, which makes use of redund…

Negative differential conductivity in far-from-equilibrium quantum spin chains
Giuliano Benenti, Giulio Casati, Tomaz Prosen +1
We show that, when a finite anisotropic Heisenberg spin-1/2 chain in the gapped regime is driven far from equilibrium, oppositely polarized ferromagnetic domains build up at the ed…
