CJM - Cuntz Algebra States Defined by Implementers of Endomorphisms of the CAR Algebra

  • . 694-708 Cuntz Algebra States Defined by Implementers of Endomorphisms of the CAR Algebra Michael J.
  • . Gabriel Abstract : TeX format We investigate representations of the Cuntz algebra mathcal{O} 2 on antisymmetric Fock space F a (mathcal{K} 1 ) defined by isometric implementers of certain quasi-free endomorphisms of the CAR algebra in pure quasi-free states varphi_{P 1 }.
  • . Restricting these states to the gauge-invariant subalgebra mathcal{F} 2 , we find that for natural choices of implementers, they are again pure quasi-free and are, in fact, essentially the states varphi P 1 .
  • . We proceed to consider the case for an arbitrary pair of implementers, and deduce that these Cuntz algebra representations are irreducible, as are their restrictions to mathcal{F} 2 .



    Citebase - Nonlinear Transformation Group of CAR Fermion Algebra
  • Authors: ; Based on our previous work on the recursive fermion system in the Cuntz algebra, it is shown that a nonlinear transformation group of the CAR fermion algebra is induced from a U(2 p ) action on the Cuntz algebra O 2 p with an arbitrary positive integer p .

  • . a ), the generated by elements of V subject to the relations f g − g f = i ( f , g ) f*=f for any f, g in V is called the canonical commutation relations (CCR) algebra .
  • . The uniqueness of the representations of this algebra when V is is discussed in the .
  • . There is also a corresponding unital, often referred to as the Weyl form of the algebra, generated by e if subject to e i f e i g = e − i ( f , g ) e i g e i f (e if )*=e -if for real numbers c 1 , c 2 .
  • . If V is equipped with a real (, ) instead, the unital *-algebra generated by the elements of V subject to the relations f g + g f = ( f , g ) f*=f for any f, g in V is called the canonical anticommutation relations (CAR) algebra .
  • . (g, f)=-(-1) |f||g| (g, f) ) such that (f, g) is real if either f or g is an even element and if both of them are odd, the unital *-algebra generated by the elements of V subject to the relations f g − ( − 1) | f | g | g f = i ( f , g ) f*=f, g*=g for any two pure elements f, g in V is the obvious super generalization which unifies CCRs with CARs.
