Polaronic correlations from optimized ancilla wave functions for the Fermi-Hubbard model

Tobias Müller, Ronny Thomale, Subir Sachdev +1

We employ a family of ancilla qubit variational wave-functions [Zhang and Sachdev, Phys. Rev. Res. 2, 023172 (2020)] to describe the polaronic correlations in the pseudo-gap metal…
