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…
Effective description of correlations for states obtained from conformal field theory
Benedikt Herwerth, Germán Sierra, J. Ignacio Cirac +1
We study states of one- and two-dimensional spin systems that are constructed as correlators within the conformal field theory of a massless, free boson. In one dimension, these ar…
Edge states for the Kalmeyer-Laughlin wave function
Benedikt Herwerth, Germán Sierra, Hong-Hao Tu +2
We study lattice wave functions obtained from the SU(2) Wess-Zumino-Witten conformal field theory. Following Moore and Read's construction, the Kalmeyer-Laughlin fractional qua…
Excited States in Spin Chains from Conformal Blocks
Benedikt Herwerth, Germán Sierra, Hong-Hao Tu +1
We develop a method of constructing excited states in one dimensional spin chains which are derived from the Wess-Zumino-Witten Conformal Field Theory (CFT) using a paren…
Spectral functions and time evolution from the Chebyshev recursion
F. Alexander Wolf, Jorge A. Justiniano, Ian P. McCulloch +1
We link linear prediction of Chebyshev and Fourier expansions to analytic continuation. We push the resolution in the Chebyshev-based computation of many-body spectral functi…
Quantum reflection from an oscillating surface
Benedikt Herwerth, Maarten DeKieviet, Javier Madronero +1
We describe an experimentally realistic situation of the quantum reflection of helium atoms from an oscillating surface. The temporal modulation of the potential induces clear side…
