FIG. 1. Phase diagram in the ( T ∗ , λ u ) plane separating the PM, FM, SG regions. We also indicate the estimated range in λ u corresponding to the FM-QLRO and transverse spin-glass phase
FIG. 2. Polarization m d1 , open symbols and nematic order parameter, [ < P 2 > ] solid symbols in terms of T ∗ for a) λ u = 0 , b) λ u = 0.8 and c) λ u = 1.6 for different system sizes L = 4 to 8 (N = 256 to 2048) for λ u = 0 and 0.8, and L = 4 to 7
FIG. 3. Log-log plot of m 2 in terms of L for : a) λ u = 0.4 and T ∗ = 0.2028, 0.3050, 0.4481, 0.5402, 0.5913, 0.6833, 1.910 from top to bottom; b) λ u = 0.8 and T ∗ = 0.1983, 0.3084, 0.4429, 0.5651, 0.6263, 0.6385, 0.6874, 1.9100

In conclusion, we have computed numerically the low lying eigenenergies of three spin-1/2 fermions in a box, interacting with an infinite scattering length in a lattice model, for

The algorithm is applicable only for cases when the exchange interaction constant is the same for all pairs of interacting spins. Any lattice architecture and

The present paper addresses the two points men- tioned above: (i) to verify the conjecture of Cardy and Jacobsen 23 on the disappearance of the latent heat in the case of a

At any point of this hypersurface the bulk and the surface of the system exhibit a transition between the phases F and P§ Such a phase transition is similar to

In Section 5 we give sufficient conditions for the existence of interfaces for global minimizers of It. On the other hand we establish the lower bound.. After most of

To expand partition functions in terms of contours, we introduce the notion of disordered « dis » boundary conditions. In accordance with defi- nitions of Section

Regarding the first eigenvalue of the MIT bag Dirac operator, we also find the first order term in the asymptotic expansion of the eigenvalues given by the high scalar
