熵变无公度跃迁

Entropic commensurate-incommensurate transition

Nikolai Nikola, Daniel Hexner, Dov Levine

摘要:

研究了一个极小平铺模型的平衡性质。该模型具有广泛的基态熵,每个基态具有准周期序列的行。据发现,从准周期性的基态的高温无序相的过渡收益通过一系列的行的周期性安排,在类似的Frenkel-Kontorova模型,但温度发挥的作用的强度的衬底电位。

英文摘要:

The equilibrium properties of a minimal tiling model are investigated. The model has extensive ground state entropy, with each ground state having a quasiperiodic sequence of rows. It is found that the transition from the quasiperiodic ground state to the high temperature disordered phase proceeds through a sequence of periodic arrangements of rows, in analogy with the Frenkel-Kontorova model, but with temperature playing the role of the strength of the substrate potential.
