Quantum Simulation of Magnetic Materials: from Ab-Initio to NISQ
Pascal Stadler, Florian G. Eich, Benedikt M. Schoenauer +5
Quantum computers are increasingly accessible, yet demonstrations of physically meaningful simulations for real materials remain scarce. In our work we simulate low-energy magnetic…
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…
A method to derive material-specific spin-bath model descriptions of materials displaying prevalent spin physics
Benedikt M. Schoenauer, Nicklas Enenkel, Florian G. Eich +4
Magnetism and spin physics are true quantum mechanical effects and their description usually requires multi reference methods and is often hidden in the standard description of mol…
Understanding Radicals via Orbital Parities
Reza G. Shirazi, Benedikt M. Schoenauer, Peter Schmitteckert +2
We introduce analysis of orbital parities as a concept and a tool for understanding radicals. Based on fundamental reduced one- and two-electron density matrices, our approach allo…
Finite-time quantum quenches in the XXZ Heisenberg chain
Benedikt Schoenauer, Dirk Schuricht
We study the time evolution of the two-point correlation functions in the XXZ Heisenberg chain after a finite-time quantum quench in the anisotropy. We compare results from numeric…
Long-lived circulating currents in strongly correlated nanorings
B. M. Schoenauer, N. M. Gergs, P. Schmitteckert +2
We study the time evolving currents flowing in an interacting, ring-shaped nanostructure after a bias voltage has been switched on. The source-to-drain current exhibits the expecte…
Observation of spin-charge separation and boundary bound states via the local density of states
Benedikt Schoenauer, Peter Schmitteckert, Dirk Schuricht
We numerically calculate the local density of states (LDOS) of a one-dimensional Mott insulator with open boundaries, which is modelled microscopically by a (extended) Hubbard chai…
