Abstract

In an abstract framework, a new concept on time operator, ultra-weak time operator, is introduced, which is a concept weaker than that of weak time operator. Theorems on the existence of an ultra-weak time operator are established. As an application of the theorems, it is shown that Schrödinger operators $${H_V}$$ H V with potentials V obeying suitable conditions, including the Hamiltonian of the hydrogen atom, have ultra-weak time operators. Moreover, a class of Borel measurable functions $$f:{\mathbb {R}}\rightarrow {\mathbb {R}}$$ f : R → R such that $$f({H_V})$$ f ( H V ) has an ultra-weak time operator is found.
