Planar Super-Landau Models
In previous papers we solved the Landau problems, indexed by 2M , for a particle on the “superflag” SU(2|1)/[U(1) × U(1)], the M = 0 case being equivalent to the Landau problem for a particle on the “supersphere” SU(2|1)/[U(1|1)]. Here we solve these models in the planar limit. For M = 0 we have a particle on the complex superplane C; its Hilbert space is the tensor product of that of the Landa...
متن کاملPlanar Super-Landau Models Revisited
We use the methods of PT -symmetric quantum theory to find a oneparameter family of ISU(1|1)-invariant planar super-Landau models with positive norm, uncovering an ‘accidental’, and generically spontaneouslybroken, N=2 worldline supersymmetry. In contrast to standard models of supersymmetric quantum mechanics, it is the norms of states rather than their energies that are parameter-dependent, an...
متن کاملWang-Landau simulation of two planar XY-models
We have performed Monte Carlo simulation of two planar XY-models using the Wang-Landau algorithm. One of these models is the standard XY-model, the other has a modified potential and exhibits a strongly first order phase transition. The first part of the work is an investigation of the growth of the energy histogram fluctuation in these continuous models. We find that these histograms saturate ...
متن کاملPerturbations of planar interfaces in Ginzburg - Landau models
Certain dissipative Ginzburg-Landau models predict existence of planar interfaces moving with constant velocity. In most cases the interface solutions are hard to obtain because pertinent evolution equations are nonlinear. We present a systematic perturbative expansion which allows us to compute effects of small terms added to the free energy functional of a soluble model. As an example, we tak...
متن کاملA Super-flag Landau Model
We consider the quantum mechanics of a particle on the coset superspace SU(2|1)/[U(1)×U(1)], which is a super-flag manifold with SU(2)/U(1) ∼= S2 ‘body’. By incorporating the Wess-Zumino terms associated with the U(1) × U(1) stability group, we obtain an exactly solvable super-generalization of the Landau model for a charged particle on the sphere. We solve this model using the factorization me...
