论文摘要
通过分析列液晶的弹性理论，我们区分了弹性常数的三个方案。在一个政权中，满足了埃里克森的不平等现象，并且局长领域的基态很统一。在第二个制度中，违反了某些必要的不平等现象，自由能在热力学上不稳定。在这些可能性之间，有一个中间政权，埃里克森的不平等现象是违反的，但系统仍然稳定。值得注意的是，溶作式染色性液体晶体位于中间状态。我们研究了该制度中导演场的非均匀结构，表明它敏感地取决于系统几何形状，并讨论对溶晶染色体液体晶体的影响。
By analyzing elastic theory for nematic liquid crystals, we distinguish three regimes of elastic constants. In one regime, the Ericksen inequalities are satisfied, and the ground state of the director field is uniform. In a second regime, certain necessary inequalities are violated, and the free energy is thermodynamically unstable. Between those possibilities, there is an intermediate regime, where the Ericksen inequalities are violated but the system is still stable. Remarkably, lyotropic chromonic liquid crystals are in the intermediate regime. We investigate the nonuniform structure of the director field in that regime, show that it depends sensitively on system geometry, and discuss the implications for lyotropic chromonic liquid crystals.
