Doping the Mott insulating state of the triangular-lattice Hubbard model reveals the Sordi transition
P. -O. Downey, O. Gingras, C. -D. Hébert +2
It has been reported that upon doping a Mott insulator, there can be a crossover to a pseudogaped metallic phase followed by a first-order transition to another thermodynamically s…
Mott transition, Widom line and pseudogap in the half-filled triangular lattice Hubbard model
P. -O. Downey, O. Gingras, J. Fournier +3
The Mott transition is observed experimentally in materials that are magnetically frustrated so that long-range order does not hide the Mott transition at finite temperature. The H…
Potential energy contribution to the thermopower of correlated electrons
R. Nourafkan, A. -M. S. Tremblay
Certain classes of strongly correlated systems promise high thermopower efficiency, but a full understanding of correlation effects on the Seebeck coefficient is lacking. This is p…
Entanglement and classical correlations at the doping-driven Mott transition in the two-dimensional Hubbard model
C. Walsh, P. Sémon, D. Poulin +2
Tools of quantum information theory offer a new perspective to characterize phases and phase transitions in interacting many-body quantum systems. The Hubbard model is the archetyp…
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…
Interaction and temperature effects on the magneto-optical conductivity of Weyl liquids
S. Acheche, R. Nourafkan, J. Padayasi +2
Negative magnetoresistance is one of the manifestations of the chiral anomaly in Weyl semimetals. The magneto-optical conductivity also shows transitions between Landau levels that…
