液晶中的skyrmion态理论：轴对称双泡（球晶）
Theory of skyrmion states in liquid crystals: axisymmetric cholesteric bubbles (spherulites)
摘要：
在Oseen-Frank理论中，我们得到了具有垂面锚定的手征液晶层中轴对称局域态的数值精确解。这些解描述了最近在受限手性向列中观察到的二维skyrmions [P.J.Acherman et al.Phys.Rev.E90，012505（2014）]。我们强调，这些孤立子状态的出现是由于一个基本的稳定机制，负责在立方helimagnets和其他非中心对称凝聚态系统的skyrmions的形成。
英文摘要：
Within the Oseen-Frank theory we derive numerically exact solutions for axisymmetric localized states in chiral liquid crystal layers with homeotropic anchoring. These solutions describe recently observed two-dimensional skyrmions in confinement-frustrated chiral nematics [P. J. Acherman et al. Phys. Rev. E 90, 012505 (2014)]. We stress that these solitonic states arise due to a fundamental stabilization mechanism responsible for the formation of skyrmions in cubic helimagnets and other noncentrosymmetric condensed-matter systems.
