我们研究了在球面约束下软排斥球柱体（SRS）系统中的双温度诱导相分离（2-TIPS）。我们采用了两种不同的锚定条件：自由锚定和切向锚定。对于自由锚定，增加堆积分数或杆长径比会抑制活性与被动子系统之间的相分离，系统对应致密-稀薄两相共存。这些现象可通过捕获效应解释，且是由约束涌现的。对于切向锚定，系统从初始各向同性态相分离为局部有序的致密区域和无序的稀薄区域。我们的工作为球形约束下二元混合物中的相分离提供了有益的见解。
英文摘要
We studied the 2-Temperature induced phase separation (2-TIPS) in a system of soft repulsive sphe rocylinders (SRS), confined on the surface of a sphere. We used two different anchoring conditions for the SRS on the spherical surface- free and tangential. For the free anchoring, increasing either the packing fraction or the rod aspect ratio suppresses phase separation between the active and passive subsystems, and the system corresponds to a dense-dilute phase co-existence. These phenomena can be explained via the trapping effect and are emergent due to the confinement. For the tangential anchoring, the system phase separates from its initial isotropic state into a locally ordered dense region and a disordered dilute region. Our work provides useful insights into phase separation in binary mixtures under spherical confinement.
