Spin-liquid versus spiral-order phases in the anisotropic triangular lattice
Luca F. Tocchio, Hélène Feldner, Federico Becca +2
We study the competition between magnetic and spin-liquid phases in the Hubbard model on the anisotropic triangular lattice, which is described by two hopping parameters t and t' i…
Mott correlated states in the underdoped two-dimensional Hubbard model: variational Monte Carlo versus a dynamical cluster approximation
Luca F. Tocchio, Hunpyo Lee, Harald O. Jeschke +2
We investigate the properties of the frustrated underdoped Hubbard model on the square lattice using two complementary approaches, the dynamical cluster extension of dynamical mean…
Strong renormalization of the Fermi-surface topology close to the Mott transition
Luca F. Tocchio, Federico Becca, Claudius Gros
The underlying Fermi surface is a key concept for strongly-interacting electron models and has been introduced to generalize the usual notion of the Fermi surface to generic (super…
