One-dimensional KDP model with random impurities

Одномерная модель KDP со случайными примесями

  • Published:
Il Nuovo Cimento B (1971-1996)

Summary

Some protons lying on the hydrogen bonds of the one-dimensional analog of the Slater KDP model are substituted by deuterium ions. The thermodynamic behaviour of this system is considered in the cases of fixed and mobile impurities. The phase transition remains of first order, but exhibits some new features.

Riassunto

Si sostituiscono alcuni protoni giacenti sui legami a idrogeno dell'analogo a una dimensione del modello KDP di Slater con ioni di deuterio. Si considera il comportamento termodinamico di questo sistema nel caso di impurità fisse e mobili. La transizione di fase rimane del primo ordine ma mostra alcune nuove caratteristiche.

Резюме

Несколько протонов, расположенных на водородных связях для одномерного аналога KDP модели Слетера, заменяются ионами дейтерия. В случаях фиксированных и движущихся примесей рассматривается термодинамическое поведение этой системы. Фазовый переход остается первого порядка, но обнаруживает некоторые новые особенности.
