Low temperature specific heat of 1D multicomponent systems at commensurate- incommensurate phase transition point

TL;DR

This paper investigates the low temperature specific heat behavior of one-dimensional multicomponent systems at the commensurate-incommensurate phase transition point, revealing a linear dependence with a diverging prefactor for canonical systems.

Contribution

It provides a detailed analysis of the low temperature specific heat near the phase transition point, highlighting the divergence in the prefactor for canonical multicomponent systems.

Findings

Specific heat linearly depends on temperature at the transition point

Prefactor of the specific heat diverges for canonical systems

Results are relevant for understanding phase transitions in 1D multicomponent systems

Abstract

Low temperature dependence of specific heat of one- dimensional multicomponent systems at the commensurate- incommensurate phase transition point is studied. It is found that for canonical systems, with a fixed total number of particles, low temperature specific heat linearly depends on temperature with a diverging prefactor.
