Query: Incommensurate spiral magnetic order on anisotropic triangular lattice:
  Dynamical mean field study in a spin-rotating frame   We study the ground-state magnetism of the half-filled Hubbard model on the
anisotropic triangular lattice, where two out of three bonds have hopping $t$
and the third one has $t^\prime$ in a unit triangle. Working in a spin-rotating
frame and using the density matrix renormalization group method as an impurity
solver, we provide a proper description of incommensurate magnetizations at
zero temperature in the framework of the dynamical mean-field theory (DMFT). It
is shown that the incommensurate spiral magnetic order for $t^\prime/t\gtrsim
0.7$ survives the dynamical fluctuations of itinerant electrons in the Hubbard
interaction range from the strong-coupling (localized-spin) limit down to the
insulator-to-metal transition. We also find that the magnetic moment reduction
from the localized-spin limit is pronounced in the vicinity of the transition
between the commensurate N\'eel and incommensurate spiral phases at
$t^\prime/t\sim 0.7$. When the anisotropy parameter $t^\prime/t$ increases from
the N\'eel-to-spiral transition, the magnitude of the magnetic moment
immediately reaches a maximum and then rapidly decreases in the range of larger
$t^\prime/t$ including the isotropic triangular lattice point $t^\prime/t=1$.
This work gives a solid foundation for further extension of the study including
nonlocal correlation effects neglected at the standard DMFT level.
