Superfluid ground state phase diagram of the two-dimensional Hubbard model in the emergent Bardeen-Cooper-Schrieffer regime
Fedor Šimkovic, Youjin Deng, Evgeny Kozik
In nonperturbative regimes, the superfluid instability in the two-dimensional Hubbard model can be described by an emergent BCS theory with small effective pairing constants. We co…

Spin and charge correlations across the metal-to-insulator crossover in the half-filled Hubbard model
Aaram J. Kim, Fedor Simkovic, Evgeny Kozik
The Hubbard model with nearest-neighbour hopping on the square lattice and an average of one electron per site is known to undergo an extended crossover from metallic to insul…
