Abstract

The anti standard-ordered distribution function is calculated in the Paul trap. We show that the real part of the ground state distribution function can take negative values in phase space, which reveals the non-classical nature of this system. This negativity is absent in its Wigner counterpart. The physical behaviour of this non-classicality resembles the uncertainty principle.
