Interaction-driven dynamics in graphene flakes as a benchmark for quantum simulation
Fabian Eickhoff, Satoshi Ejima, Lukas Windgätter +4
We study interaction-driven ultrafast dynamics in finite graphene flakes following an optical pump quench in an interacting tight-binding model. By comparing exact real-time evolut…
System-bath model for quantum chemistry
Dmitry S. Golubev, Reza G. Shirazi, Vladimir V. Rybkin +3
We propose an approximate mapping of a molecular Hamiltonian to a Hamiltonian of qubits, which allows for high accuracy quantum chemistry calculations of vertical excitation energi…
Applicability and limitations of cluster perturbation theory for Hubbard models
Nicklas Enenkel, Markus Garst, Peter Schmitteckert
We present important use cases and limitations when considering results obtained from Cluster Perturbation Theory (CPT). CPT combines the solutions of small individual clusters of…
Observation of separated dynamics of charge and spin in the Fermi-Hubbard model
Frank Arute, Kunal Arya, Ryan Babbush +96
Strongly correlated quantum systems give rise to many exotic physical phenomena, including high-temperature superconductivity. Simulating these systems on quantum computers may avo…
Learning DFT
Peter Schmitteckert
We present an extension of reverse engineered Kohn-Sham potentials from a density matrix renormalization group calculation towards the construction of a density functional theory f…
Löwdin's symmetry dilemma within Green functions theory for the one-dimensional Hubbard model
J. -P. Joost, N. Schlünzen, S. Hese +4
The energy gap of correlated Hubbard clusters is well studied for one-dimensional systems using analytical methods and density-matrix-renormalization-group (DMRG) simulations. Beyo…
