Fault-Tolerant Quantum Simulation of Generalized Hubbard Models

PRX Quantum
Quantum simulations of strongly interacting fermionic systems, such as those described by the Hubbard model, are promising candidates for useful early fault-tolerant quantum computing applications.

Link auxiliary field method in the extended Hubbard model

Physical Review E, 2023
The aim of this work is to generalize the method of Hubbard fields in fermion Quantum Monte Carlo simulation to the case of link fields. The introduced Hubbard link fields play a role of the interaction fields responsible for the attraction and repulsion of electronic excitations at the nodes.

Clusterization transition between cluster Mott insulators on a breathing kagome lattice

Physical Review Research, 2020
Motivated by recent experimental and numerical progress on various cluster Mott insulators, we study an extended Hubbard model on a breathing kagome lattice with a single electron orbital and 1/6 electron filling.

Hidden Charge Orders in Low-Dimensional Mott Insulators

Applied Sciences, 2019
The opening of a charge gap driven by interaction is a fingerprint of the transition to a Mott insulating phase. In strongly correlated low-dimensional quantum systems, it can be associated to the ordering of hidden non-local operators.

Experimental realization of an extended Fermi-Hubbard model using a 2D lattice of dopant-based quantum dots

Nature Communications, 2022
Atomically precise artificial lattices of dopant-based quantum dots offer a tunable platform for simulations of interacting fermionic models. By leveraging advances in fabrication and atomic-state control, Wang et al. report quantum simulations of the 2D
