相互作用费米子或硬核玻色子系统中条纹相的稳定性和性质

Stability and properties of striped phases in systems of interacting fermions or hard-core bosons

Volodymyr Derzhko

摘要:

在这篇论文中,我们讨论凝聚态物质中的特殊集体现象--条纹结构的形成。这种结构在凝聚态物理学的不同分支中被观察到,如表面物理学或高温超导体物理学。这些准一维物体出现在理论分析以及不同理论模型的计算机模拟中。在这里,感兴趣的主要话题是在某些量子模型中的条纹结构的稳定性,其中结晶的趋势与相分离的趋势竞争,以及这些结构的一些基本性质。

英文摘要:

In this thesis we deal with the specific collective phenomena in condensed matter - striped-structures formation. Such structures are observed in different branches of condensed matter physics, like surface physics or physics of high-temperature superconductors. These quasi-one-dimensional objects appear in theoretical analyses as well as in computer simulations of different theoretical models. Here, the main topic of interest is the stability of striped structures in certain quantum models, where a tendency towards crystallization competes with a tendency towards phase separation, and some basic properties of these structures.
