Landau Theory of the Phase Transitions in Half Doped Manganites: Interplay of Magnetic, Charge and Structural Orders
Fan Zhong, Z. D. Wang
The order parameters of the magnetic, charge and structural orders at half-doped manganites are identified. A corresponding Landau theory of the phase transitions is formulated. Ma…
Symmetry Origin of the Phase Transitions and Phase Separation in Manganites at Low Doping
Fan Zhong, Z. D. Wang
We analyze the symmetry changes of the paramagnetic to the A-type antiferromagnetic and to the ferromagnetic phase transitions in undoped and moderately doped LaMnO, respective…
Unified theory of phase separation and charge ordering in doped manganite perovskites
Shun-Qing Shen, Z. D. Wang
A unified theory is developed to explain various types of electronic collective behaviors in doped manganites RXMnO (R = La, Pr,Nd etc. and X = Ca, Sr, Ba etc.). St…
Sub-Dominant Pairing Channels in Unconventional Superconductors: Ginzburg-Landau Theory
Qiang-Hua Wang, Z. D. Wang, Q. Li
A Ginzburg-Landau theory is developed for unconventional superconductors with the three relevant singlet pairing channels. Various consequences of the sub-dominant channels (i.e.,…
