Efficient Fermi-Hubbard model ground-state preparation by coupling to a classical reservoir in the instantaneous-response limit
Zekun He, Lorenzo Del Re, A. F. Kemper +1
Preparing the ground state of the Fermi-Hubbard model is challenging, in part due to the exponentially large Hilbert space, which complicates efficiently finding a path from an ini…

Attractive effect of a strong electronic repulsion -- the physics of vertex divergences
M. Reitner, P. Chalupa, L. Del Re +4
While the breakdown of the perturbation expansion for the many-electron problem has several formal consequences, here we unveil its physical effect: Flipping the sign of the effect…
