Fundamental length in quantum theories with PT-symmetric Hamiltonians
Original language description
One-dimensional motion of a quantum point particle is usually described by its wave function Sigma(x), where the argument x is an element of R represents a (measurable) coordinate and where the integrated probability density is normalized to one, integral Sigma(*)(x)Sigma(x)=1. The direct observability of x may be lost in PT-symmetric quantum mechanics where a "smeared" metric kernel Theta(')((x,x))not equal delta(x-x(')) may enter the double-integral normalization Sigma(*)(x)Theta(')((x,x))Sigma(x('))=1. We argue that such a formalism proves particularly suitable for the introduction of a nonvanishing fundamental length theta > 0, which would characterize the "smearing width" of the kernel Theta(')((x,x)). The technical feasibility of such a project is illustrated via a toy family of Hamiltonians H-(N)(lambda) taken from Ref. 11. For each element of this family the complete set of all the eligible metric kernels Theta(')((x,x))((N))(lambda) is constructed in closed form.
