DMRG and periodic boundary conditions: a quantum information perspective
F. Verstraete, D. Porras, J. I. Cirac
We introduce a picture to analyze the density matrix renormalization group (DMRG) numerical method from a quantum information perspective. This leads us to introduce some modificat…

Implementation of Spin Hamiltonians in Optical Lattices
J. J. Garcia-Ripoll, M. A. Martin-Delgado, J. I. Cirac
We propose an optical lattice setup to investigate spin chains and ladders. Electric and magnetic fields allow us to vary at will the coupling constants, producing a variety of qua…
