Field Tensor Network States
Anne E. B. Nielsen, Benedikt Herwerth, J. Ignacio Cirac +1
We define a class of tensor network states for spin systems where the individual tensors are functionals of fields. The construction is based on the path integral representation of…

Bosonic Gaussian states from conformal field theory
Benedikt Herwerth, Germán Sierra, J. Ignacio Cirac +1
We study nonchiral wave functions for systems with continuous spins obtained from the conformal field theory (CFT) of a free, massless boson. In contrast to the case of discrete sp…
