论文摘要
我们调查了一个带有阶参数的电子系统的条纹非元中相的可能性，该阶参数线性耦合到弹性自由度，并通过电子相变而调节。我们发现，在边界条件造成了Eleast不兼容的有限系统中，可能会在电子过渡的附近出现条纹模式。当获得的弹性能克服典型的电子和域壁能量成本时，条纹会稳定。在薄膜几何形状中，发现条纹延伸到整个系统深度。我们还研究了一阶相变的旋转区域的相位分数的行为。还讨论了条纹的方向和更复杂的模式的可能性。
We investigate the possibility of a striped inhomoegenous phase occurring as an electronic system with an order parameter linearly coupled to the elastic degrees of freedom is tuned through the electronic phase transition. We find that in finite systems where boundary conditions create an eleastic incompatibility, a stripe pattern may emerge in the vicinity of the electronic transition. Stripes are stabilized when the gained elastic energy overcomes the typical electronic and domain wall energy costs. In thin film geometries, the stripes are found to extend across the entire depth of the system. We also study the behavior of the phase fraction across the spinodal region of a first order phase transition. The orientation of stripes and the possibility of more complicated patterns is also discussed.
