Strange Metal Solution in the Diagrammatic Theory for the Hubbard Model
Aaram J. Kim, Philipp Werner, Evgeny Kozik
We show that the numerically exact bold-line diagrammatic theory for the Hubbard model exhibits a non-Fermi-liquid (NFL) strange metal state, which is connected to the SYK NFL…
Tracking the Footprints of Spin Fluctuations: A MultiMethod, MultiMessenger Study of the Two-Dimensional Hubbard Model
Thomas Schäfer, Nils Wentzell, Fedor Šimkovic +23
The Hubbard model represents the fundamental model for interacting quantum systems and electronic correlations. Using the two-dimensional half-filled Hubbard model at weak coupling…
Entropy in the non-Fermi-liquid regime of the doped Hubbard model
Connor Lenihan, Aaram J. Kim, Fedor Šimkovic IV. +1
We study thermodynamic properties of the doped Hubbard model on the square lattice in the regime of strong charge and spin fluctuations at low temperatures near the metal-to-insula…
