Phase Behaviour of X-Shaped Liquid Crystalline Molecules
Dan Wei, Zhijuan He, Yunqing Huang +2
X-shaped liquid crystalline molecules (XLCMs) are obtained by tethering two flexible end A-blocks and two flexible side B-blocks to a rigid backbone (R). A rich array of ordered st…
Stability of diverse dodecagonal quasicrystals in T-shaped liquid crystalline molecules
Xin Wang, An-Chang Shi, Pingwen Zhang +1
Quasicrystals are intriguing ordered structures characterized by the lack of translational symmetry and the existence of rotational symmetry. The tiling of different geometric unit…
Designing a minimal Landau theory to stabilize desired quasicrystals
Wei Si, Shifeng Li, Pingwen Zhang +2
Interparticle interactions with multiple length scales play a pivotal role in the formation and stability of quasicrystals. Choosing a minimal set of length scales to stabilize a g…
Phase behavior of symmetric diblock copolymers under 3D soft confinement
Zhijuan He, Jin Huang, Kai Jiang +1
The phase behavior of symmetric diblock copolymers under three-dimensional (3D) soft confinement is investigated using the self-consistent field theory. The soft confinement is rea…
Nucleation and phase transition of decagonal quasicrystals
Tiejun Zhou, Lei Zhang, Pingwen Zhang +2
In this work, we study the nucleation of quasicrystals from liquid or periodic crystals by developing an efficient order-order phase transition algorithm, namely the nullspace-pres…
