Transport enhancement from incoherent coupling between one-dimensional quantum conductors
J. J. Mendoza-Arenas, M. T. Mitchison, S. R. Clark +3
We study the non-equilibrium transport properties of a highly anisotropic two-dimensional lattice of spin-1/2 particles governed by a Heisenberg XXZ Hamiltonian. The anisotropy of…

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…
