内腔多原子直接俘获的强耦合腔量子力学系统的构建 Hot! Construction of a strongly coupled cavity quantum electrodynamics system with easy accessibility of single or multiple intra-cavity atoms
腔内中性原子的长时间控制与俘获一直是腔量子电动力学(QED)中的一个难题, 极大地制约了人们相干操控单原子及其与光相互作用的研究. 本文基于传统Fabry-Perot光学腔, 设计了一套易于内腔原子操控的强耦合腔QED系统, 其典型参数为: 腔长3.5 mm精细度约为57000, (g0,κ,γ)=2π ×(1.48, 0.375, 2.61) MHz, 临界光子数和原子数分别为1.54和0.89. 该系统的特点是: 能够在腔内直接实现冷原子磁光阱, 并建立腔内光学晶格, 实现腔内可控数目的中性原子的长时间俘获. 通过合理选择构建光学偶极阱和原子成像系统, 可实现对腔内单个原子或原子阵列的操控、探测、成像等. 该系统可以克服传统腔QED系统中转移原子的困难, 大幅增加腔内原子的寿命, 为构建以腔QED系统为基础的量子信息演示平台提供了一种可能.

含微孔洞脆性材料的冲击响应特性与介观演化机制 Hot! Shock response and evolution mechanism of brittle material containing micro-voids
微孔洞显著地影响着脆性材料的冲击响应, 理解其介观演化机制和宏观响应规律将使微孔洞有利于而无害于脆性材料的工程应用. 通过建立能够准确表现材料弹性性质和断裂演化的格点-弹簧模型, 本文揭示了孔洞的演化对于脆性材料的影响. 冲击下孔洞导致的塌缩变形和从孔洞发射的剪切裂纹所导致的滑移变形产生了显著的应力松弛, 并调制了冲击波的传播. 在多孔脆性材料中, 冲击波逐渐展宽为弹性波和变形波. 变形波在宏观上类似于延性金属材料的塑性波, 在介观上对应于塌缩变形和滑移变形过程. 样品中的气孔率决定了脆性材料的弹性极限, 气孔率和冲击应力共同影响着变形波的传播速度和冲击终态的应力幅值. 含微孔洞脆性材料在冲击波复杂加载实验、功能材料失效的预防、建筑物防护等方面具有潜在的应用价值. 本文获得的冲击响应规律有助于针对特定应用优化设计脆性材料的冲击响应和动态力学性能.

TiF3, TiCl3中阴阳离子对LiBH4协同催化机理的第一性原理研究 A first principles study on the synergistic catalytic mechanism of anion, cation ions in TiF3, TiCl3 catalysts for LiBH4 hydrogen-storage materials
应用基于密度泛函理论的第一原理方法, 研究了TiF3, TiCl3催化剂中阴阳离子对LiBH4的协同催化机理. 研究发现i金属Ti相对于卤族元素掺杂不容易实现; 金属和卤族元素同时掺杂比Ti单独掺杂容易实现; 对TiF3催化剂, 一种元素掺杂的实现有助于另一种元素掺杂的实现, 这大大提高了掺杂浓度. 基于电子结构分析, 得出卤族元素单独掺杂会降低LiBH4的稳定性; Ti单独掺杂使LiBH4费米能级升高、在带隙中引入缺陷能级、使B–H键结合减弱, 这些可能是Ti的卤化物催化剂大大改善LiBH4释氢性能的原因. LiBH4中加入Ti的卤化物催化剂改善其释氢性能主要是由于催化剂使B–H共价结合减弱, 这使得氢扩散容易. TiF3, TiCl3催化剂, 在LiBH4可逆释氢反应过程中F,Ti协同降低B–H共价结合, 而Cl, Ti这种协同作用不显著, 这是TiF3对LiBH4催化效果优于TiCl3的原因.
