The effects of weakly coupled plasmas on the dynamic dipole polarizabilities of the H{sup −} and Ps{sup −} ions are investigated using highly correlated exponential wave functions. The Debye-Hückel shielding approach of plasma modeling is used to represent weakly coupled plasma environments. In free-atomic cases, results obtained from the present study for H{sup −} are in agreement with the available calculations and results for Ps{sup −} are reported for the first time. Frequency-dependent polarizabilities of H{sup −} and Ps{sup −} as functions of screening parameter are also presented for the first time.
