Ground state phase diagrams

Fig.5. The ground state phase diagram of the triangular lattice strip with n=2. The shaded region associates with the intermediate values of the ground state spin, the above consideration, it can be shown that our lattice at N>L has the ferromagnetic ground state if the electron concentration p obeys the condition...

Fig. 13 Schematic ground-state phase diagram for the spin-1/2 XXZ model in the magnetic field in one [115] and two dimensions [119]. The line of A = 0 corresponds to the half-filling in the Holstein model. Antiferromagnetic, ferromagnetic, and XY phases correspond, respectively, to charge density wave, band insulating, and superconducting states in the Holstein model...

In two dimensions, the ground-state phase diagram has been obtained by quantum Monte Carlo simulation [118,119]. There is a little difference in the vicinity of the Heisenberg point (/ = J ) from that in one dimension, but they are qualitatively quite similar. 

The results of systematic study of the ground state properties for systems characterized by different symmetry of the surface lattice and different size of the adsorbed particles have been presented in Ref. [121]. The obtained ground state phase diagrams have demonstrated that the structure of the ordered state is very sensitive to the system geometry as... 

Dipolar soft spheres solidify into a bet crystal at p 0.87 for k = 6.67 (p, = 3, r = 1.35) and p 0.8 for A, = 9 (p = 3,T = 1) [102]. Inspection of the pair distribution shows that in the ferroelectric liquid the short range spatial correlations are similar to those in the bet crystal [102]. The ground state phase diagram of DSS is quite complex depending on the softness parameter n [145]. For n = 12 the sequence of transitions with increasing density is fco (face-centred-orthorhombic)-bct-bco-hexc-bco-fcc for p. = I [145].
