Novel Cyano-Bridged 4f-3d Coordination Polymers with a Unique 2D Topological Architecture and Unusual Magnetic Behavior
Bao-Qing Ma, Song Gao, Gang Su +1
Cyano-bridged bimetallic hybrid Prussian Blue one- to three-dimensional (1D-3D) coordination polymers based on [M(CN)6]3- (M = Fe, Cr, Mn) have attracted great attention because of…
Observation of an unusual field dependent slow magnetic relaxation and two distinct transitions in a family of new complexes
Song Gao, Gang Su, Tao Yi +1
An unusual field dependent slow magnetic relaxation and two distinct transitions were observed in a family of new rare earth-transition metal complexes, [Ln (bipy) (HO)…
Towards Bose-Einstein Condensation of Electron Pairs: Role of Schwinger Bosons
Gang Su, Masuo Suzuki
It can be shown that the bosonic degree of freedom of the tightly bound on-site electron pairs could be separated as Schwinger bosons. This is implemented by projecting the whole H…
Does the 2D Hubbard Model Really Show d-Wave Superconductivity?
Gang Su
Some issues concerning the question if the two-dimensional Hubbard model really show d-wave superconductivity are briefly discussed.
Off-Diagonal Long-Range Order in Bose Liquids: Irrotational Flow and Quantization of Circulation
Gang Su, Masuo Suzuki
On the basis of gauge invariance, it is proven in an elementary and straightforward manner, but without invoking any {\it ad hoc} assumption, that the existence of off-diagonal lon…
