Abstract:
We examine the possibility of a direct Fock representation of
the recently obtained non-trivial central extensions
of the Heisenberg algebra, generated by elements
and
E satisfying the commutation relations
,
and
,
where a and
are dual, h is self-adjoint, E is the non-zero self-adjoint
central element and
We define the exponential vectors associated with the
Fock space, we compute their Leibniz function (inner product), we describe the
action of a,
and h on the exponential vectors and we compute the moment generating and
characteristic functions of the classical random variable corresponding to the
self-adjoint operator
