Collective inertia of Nambu-Goldstone mode from linear response theory

Background: Spurious zero-energy Nambu-Goldstone (NG) modes appear when the symmetry of a system is spontaneously broken. The Thouless-Valatin inertia, the collective inertia of the NG mode, contains important information concerning collective motion. Purpose: To establish an efficient and precise method for deriving the collective inertia and the conjugate operator of a NG mode, we derive an expression for the response function in terms of the coordinate-momentum representation of the quasiparticle random-phase approximation which is valid even if a symmetry-restoring zero-energy mode is present. Methods: We use the finite amplitude method for computing the response function of superfluid nuclei with the nuclear density functional theory. Results: We derived analytically the collective inertia and the conjugate coordinate operator of the NG mode from the zero-energy linear response with the momentum operator of the NG mode. The formulation is tested in the cases of translational and pairing rotational modes. Illustrative calculations are performed for the neutron pairing rotation in Sn isotopes, the proton pairing rotation in N = 82 isotones, and the neutron and proton pairing rotations around the 130Xe nucleus. Conclusions: The proposed formulation allows us to compute the collective inertia of the NG mode precisely and efficiently. The conjugate coordinate operator can be utilized to remove spurious contributions to the strength distribution in the finite amplitude method.Comment: 14 pages, 6 figures, 1 table, submitted to Phys.

The Impact of China’s Land Finance on Residential Real Estate Market: Mechanism, Effect and Solution

经营性用地招拍挂制度实施以来，中国土地出让收入规模迅速膨胀，占地方财力的比重也逐年增大。于此同时，中国的房地产市场总体呈现过热，表现为房价和楼面地价明显上升，以及房地产开发投资相对规模逐年扩大，其中，住宅市场的过热现象最为突出。学术界对地方政府的“以地生财”现象提出了种种批评，并且大多将其视为房地产市场过热的重要原因。但这些研究大多流于表面，没能基于中国的制度背景系统地建立理论框架并展开严谨的实证分析。有别于先前研究，本文立足于中国的土地招拍挂制度，在地方政府拥有完全信息和开发商不“囤地”的条件下建立了一个描述住房价格主要影响因素和住宅地价形成机制的理论框架，在此基础上分别研究了地方政府在短期...Since the implementation of bid invitation, auction and listing (BAL) system of operating land, China's land transfer income scale has seen a rapid expansion, and its share of local financial resources has also increased year by year.

Host location behavior of Aedes albopictus and Empoasca vitis: olfactory and visual effects on their orientation

在昆虫宿主定位行为中，嗅觉与视觉究竟哪个更为重要至今尚无定论。本研究选择福建地区广泛分布、并且具有重大危害的白纹伊蚊（Aedesalbopictus）和假眼小绿叶蝉（Empoascavitis）为研究对象，以干扰害虫对宿主生物的定向通讯行为为研究思路，整合形态学、分子生物学和行为学方法试图揭示嗅觉和视觉在昆虫宿主定位行为中的作用。以期深入理解昆虫的宿主定位行为机制并为害虫防治提供新思路。研究结果如下： （1）应用RACE技术获得白纹伊蚊嗅觉共受体基因（AalbOrco）全长编码序列。结构预测表明AalbOrco为七跨膜蛋白并且N端在胞内而C端在胞外。序列比对显示AalbOrco与其它双翅目昆...For the olfaction and vision, which one in the host location behavior of insects is more important are still inconclusive. Here, two insects (Aedes albopictus and Empoasca vitis) which are significant hazard in Fujian, China were investigated for deeper understanding the phenomenon and its mechanism. Moreover, the studies may propose some new correspondingly strategies for pest control. The import...学位：理学博士院系专业：生命科学学院_动物学学号：2162012015376
