“…Recently, a single particle susceptibility has been reinvestigated by using quantum mechanics [6,7] to discuss the pressure-temperature phase diagram of KH 2 PO 4 [8], which is famous for a proton tunneling [9]. The Barrett equation [10] has been derived for the static susceptibility, and the pressure dependence of the transition line was calculated [7].…”

“…The statistical theory of the phase transitions in ADP type crystals, based on the principles of the proton ordering model proposed in [7][8][9] for the KH 2 PO 4 type crystals, was developed in [4,10]. In [4] the free energy of the proton system was calculated within the four-particle cluster approximation, and possible types of proton ordering were established.…”

“…In this particular case, it goes from ≃ 122 K in KDP to ≃ 229 K in the deuterated compound (DKDP). The origin of this huge isotope effect is still controversial, and has been mostly understood in terms of the quantum tunneling model proposed by Blinc, [1] later modified by inclusion of the coupling between proton motion and the K-PO 4 dynamics. [2] While direct experimental indications of tunneling have recently emerged [3], the connection between proton tunneling and isotope effect remains unclear.…”
