Lattice Laughlin States of Bosons and Fermions at Filling Fractions
Hong-Hao Tu, Anne E. B. Nielsen, J. Ignacio Cirac +1
We introduce a two-parameter family of strongly-correlated wave functions for bosons and fermions in lattices. One parameter, , is connected to the filling fraction. The other o…
Unifying Projected Entangled Pair States contractions
Michael Lubasch, J. Ignacio Cirac, Mari-Carmen Bañuls
The approximate contraction of a Projected Entangled Pair States (PEPS) tensor network is a fundamental ingredient of any PEPS algorithm, required for the optimization of the tenso…
Purifications of multipartite states: limitations and constructive methods
Gemma De las Cuevas, Norbert Schuch, David Pérez-García +1
We analyze the description of quantum many-body mixed states using matrix product states and operators. We consider two such descriptions: (i) as a matrix product density operator…
