Spin and Charge Conductivity in the Square Lattice Fermi-Hubbard Model
Linh Pham, Ehsan Khatami
Dynamical properties are notoriously difficult to compute in numerical treatments of the Fermi-Hubbard model, especially in two spatial dimensions. However, they are essential in p…
Competition of fermion pairing, magnetism, and charge order in the spin-doped attractive Hubbard gas
Thomas Hartke, Botond Oreg, Chunhan Feng +7
The tension between fermion pairing and magnetism affects numerous strongly correlated electron systems, from high-temperature cuprates to twisted bilayer graphene. Exotic forms of…
CMT-Benchmark: A Benchmark for Condensed Matter Theory Built by Expert Researchers
Haining Pan, James V. Roggeveen, Erez Berg +16
Large language models (LLMs) have shown remarkable progress in coding and math problem-solving, but evaluation on advanced research-level problems in hard sciences remains scarce.…
Finite-Temperature Kinetic Ferromagnetism in the Square Lattice Hubbard Model
Robin C. Newby, Ehsan Khatami
While the exact phase diagram of the Fermi-Hubbard model remains poorly understood despite decades of progress, nearly 60 years ago, Nagaoka proved that a single dopant in an other…
Autoregressive neural quantum states of Fermi Hubbard models
Eduardo Ibarra-García-Padilla, Hannah Lange, Roger G Melko +4
Neural quantum states (NQS) have emerged as a powerful ansatz for variational quantum Monte Carlo studies of strongly-correlated systems. Here, we apply recurrent neural networks (…
Structural complexity of snapshots of 2D Fermi-Hubbard systems
Eduardo Ibarra-García-Padilla, Stephanie Striegel, Richard T. Scalettar +1
The development of quantum gas microscopy for two-dimensional optical lattices has provided an unparalleled tool to study the Fermi-Hubbard model (FHM) with ultracold atoms. Spin-r…
