the wavefunction when antiparallel spin electrons coincide and its relation to the ground state electron density in the hookean atom
Chemical Physics Letters, 2000Co-Authors: N H March, Claudio Amovilli, Douglas J KleinAbstract:Abstract For a specific force constant, the Spatial Form of the ground-state wavefunction Ψ( r 1 , r 2 ) is known analytically for the Hookean atom in which two electrons repel coulombically. Here, it is first shown that the wavefunction Ψ( r , r ) for the antiparallel spin electrons at the same position r is sufficient to construct the ground-state density in this model example. An off-diagonal generalization is then effected, which relates the one-particle density matrix to the electron pair correlation function, again for this same model.

comment on momentum density and Spatial Form of correlated density matrix in model two electron atoms with harmonic confinement
Physical Review A, 2008Co-Authors: Sebastien RagotAbstract:In a recent paper A. Akbari, N. H. March, and A. Rubio [Phys. Rev. A 76, 032510 (2007)] investigated the one-electron reduced density matrix and the momentum density of several two-electron model atoms, including Hooke's atom. The method used by the authors for deriving an integral Form of the momentum density is in fact the most suited for deriving a closed-Form expression of the exact reciprocal Form factor, in a special case. This function is important inasmuch as it reflects the off-diagonal side of the exact reduced density matrix.

influences of urban Spatial Form on urban heat island effects at the community level in china
Sustainable Cities and Society, 2020Co-Authors: Andong Guo, Jun Yang, Xiangming Xiao, Jianhong Xia, Cui JinAbstract:Abstract Owing to increasing population densities and impervious surface areas, heat island effects increasingly dominate urban environments and hinder sustainable development. The urban Spatial Form plays an important role in mitigating urban heat islands. Taking Ganjingzi District, Dalian, as an example, this study considered urban Spatial Form at the community scale using Spatial autocorrelation and Spatial regression methods to explore 2003–2018 Spatial and temporal differentiation characteristics and driving factors of Land Surface Temperature (LST). The LST of each community showed a gradually increasing trend; high values (>30°C) were concentrated in central and eastern areas; low values were (

the impact of Spatial Form of urban architecture on the urban thermal environment a case study of the zhongshan district dalian china
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2018Co-Authors: Jun Yang, Jianhong Cecilia Xia, Cui JinAbstract:The correlation of Spatial variation in land surface temperature with building height and density in Zhongshan District, Dalian, China, is investigated over the period 2003–2013. We utilize remote sensing data and multisource land-use data, which we evaluate using a combination of a single-window algorithm and correlation analysis. The results show that: 1) during 2003–2013, the number of high surface temperature regions increased by 4339 grid cells (out of a total of 53 601), with most of the high-temperature grid cells distributed along Jiefang Road and Zhongnan Road in the northern part of Zhongshan District. Ninety-eight percent of grid cells had temperature ranges of 293–309 K in July 2003, 296–310 K in August 2003, 295–308 K in July 2008, 296–311 K in August 2008, 305–314 K in July 2013, and 303–318 K in August 2013; 2) during 2003–2008, the number of low-rise buildings increased by 140%, and the number of multistory buildings increased by 100%. During 2008–2013, the number of buildings in all height categories remained relatively unchanged, with the exception of an 11% decrease in the number of low-rise buildings; 3) surface temperature showed weak correlation with building height (0.314, 0.346, and 0.361 in 2003, 2008, and 2013, respectively) but moderate correlation with building density (0.511, 0.533, and 0.563, respectively).
