AutoHF: a general Hartree-Fock solver utilizing direct energy minimization with automatic differentiation
Ryan Levy, Brandon Eskridge, Lukas Weber +2
The paper introduces AutoHF, a general-purpose Hartree‑Fock solver that finds the optimal Slater determinant for quantum many‑fermion Hamiltonians by directly minimizing the variat…
Importance of effective Coulomb interactions for in cuprates
JakÅ¡a VuÄiÄeviÄ, Upendra Kumar, Chia-Nan Yeh +2
Cuprate superconductors exhibit the highest observed superconducting at atmospheric pressure. However, the magnitude of varies significantly between different cuprates.…
Electronic correlations and dynamical screening with ab initio quantum embedding
Chia-Nan Yeh, Francesco Petocchi, Alexander Hampel +4
First-principles descriptions of correlated quantum materials require a simultaneous treatment of strong local many-body effects and nonlocal dynamical screening. We present an eff…
Interaction-Driven Ferrimagnetic Stripes in the Extended Hubbard Model
Chunhan Feng, Miguel A. Morales, Shiwei Zhang
Long-range interactions can qualitatively reorganize correlated-electron ground states. In the square-lattice Hubbard model, on-site repulsion produces antiferromagnetic spin and c…
Neural Network Discovery of Paired Wigner Crystals in Artificial Graphene
Conor Smith, Yubo Yang, Zhou-Quan Wan +3
Moiré systems have emerged as an exciting tunable platform for engineering and probing quantum matter. A large number of exotic states have been observed, stimulating intense effo…
Engineering Hubbard models with gated two-dimensional moiré systems
Yiqi Yang, Yubo Yang, Miguel A. Morales +1
Lattice models are powerful tools for studying strongly correlated quantum many-body systems, but their general lack of exact solutions motivates efforts to simulate them in tunabl…
