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…
