Operator ordering and Classical soliton path in Two - dimensional N = 2 supersymmetry with Kähler potential
We investigate a 2-dimensional N = 2 supersymmetric model which consists of n chiral superfields with Kähler potential. When we define quantum observables, we are always plagued by operator ordering problem. Among various ways to fix the operator order, we rely upon the supersymmetry. We demonstrate that the correct operator order is given by requiring the super Poincaré algebra by carrying out...
متن کاملOperator ordering in Two - dimensional N = 1 supersymmetry with curved manifold
We investigate an operator ordering problem in two-dimensional N = 1 supersymmetric model which consists of n real superfields. There arises an operator ordering problem when the target space is curved. We have to fix the ordering in quantum operator properly to obtain the correct supersymmetry algebra. We demonstrate that the super-Poincaré algebra fixes the correct operator ordering. We obtai...
متن کاملNumber Operator Algebras and Generalizations of Supersymmetry
Several quantum systems with exotic statistics have been used in the last few years to extend supersymmetry. We show how all these systems fit into the picture of what we call “Number Operator Algebras”.
متن کاملDirac versus reduced quantization and operator ordering
We show an equivalence between Dirac quantization and the reduced phase space quantization. The equivalence of the both quantization methods determines the operator ordering of the Hamiltonian. Some examples of the operator ordering are shown in simple models.
متن کاملNonexponential evolution equations and operator ordering
NonexponeutiaI evolution equations can be treated using a formalism involving the evolution operator method, which, unlike the ordinary case, is not expressed in terms of exponential operators. The use of this technique requires particular care associated with the operator ordering. In this paper, we will present a first systematic approach to this type of problems. @ 2005 Elsevier Ltd.
