We propose a pseudospin model for proton glasses of the Rb₁₋x(NH₄)xH₂PO₄(Rb₁₋x(ND₄)xD₂PO₄) type, which takes into account the energy levels of hydrogens (deuterons) around the PO₄ group, long-range interactions between the hydrogen bonds, and an internal random deformational field. Within the framew...
