A Practical Introduction to VQE: Methods, Challenges, and Applications in Physics and Chemistry
Jannis Ehrlich, Felix Rupprecht, Konstantin Lamp +6
The Variational Quantum Eigensolver (VQE) has become a central hybrid quantum-classical method for addressing electronic structure and materials science problems on near-term quant…
Variational quantum-algorithm based self-consistent calculations for the two-site DMFT model on noisy quantum computing hardware
Jannis Ehrlich, Daniel Urban, Christian Elsässer
Dynamical Mean Field Theory (DMFT) is one of the powerful computational approaches to study electron correlation effects in solid-state materials and molecules. Its practical appli…
Functional renormalization group for fermion lattice models in three dimensions: application to the Hubbard model on the cubic lattice
Jannis Ehrlich, Carsten Honerkamp
The channel-decomposed functional renormalization group (FRG) approach, most recently in the variant of truncated-unity-(TU-)FRG, has so far been used for various two-dimensional m…
Truncated-Unity Parquet Equations: Application to the Repulsive Hubbard Model
C. J. Eckhardt, G. A. H. Schober, J. Ehrlich +1
The parquet equations are a self-consistent set of equations for the effective two-particle vertex of an interacting many-fermion system. The application of these equations to bulk…
Truncated unity functional renormalization group for multiband systems with spin-orbit coupling
G. A. H. Schober, J. Ehrlich, T. Reckling +1
Although the functional renormalization group (fRG) is by now a well-established method for investigating correlated electron systems, it is still undergoing significant technical…
