@article{Petric2021FiniteAI, title={Finite and infinite matrix product states for Gutzwiller projected mean-field wave functions}, author={Gabriel Petrică and B. Zheng and Garnet Kin-Lic Chan and Bryan K. Clark}, journal={Physical Review B}, year={2021}, volume={103} }

Matrix product states (MPS) and `dressed' ground states of quadratic mean fields (e.g. Gutzwiller projected Slater Determinants) are both important classes of variational wave-functions. This latter class has played important roles in understanding superconductivity and quantum spin-liquids. We present a novel method to obtain both the finite and infinite MPS (iMPS) representation of the ground state of an arbitrary fermionic quadratic mean-field Hamiltonian, (which in the simplest case is a…

Gutzwiller projected wave functions in the fermionic theory of S=1 spin chains

- Physics, Mathematics

We study in this paper a series of Gutzwiller projected wave functions for S = 1 spin chains obtained from a fermionic mean-field theory for general S> 1/2 spin systems [Liu, Zhou, and Ng, Phys. Rev.…

Density matrix embedding: a simple alternative to dynamical mean-field theory.

It is proposed that the low-lying entanglement spectrum can be used as a "fingerprint" to identify topological order and is compared with a generic 5/2 state obtained by finite-size diagonalization of the second-Landau-level-projected Coulomb interactions.
