The spin-1/2 dimerized antiferromagnetic system is related to spin-Peierls tran-sition.There are still some discrepancy on the behavior of the ground energy densityand energy gap,such as pure power-law,logarithmic correction to the pure power-law in the uniform,integer powers in the dimerized limit,etc.

自旋S-1/2的二聚化反铁磁链与spin-Peierls相变有关，在对其基态能和激发能隙的临界行为描述上仍存在一些不完全一致的观点：如均匀极限的纯幂级数律，纯幂级数律的对数修正；二聚化极限的整数幂级数行为等。

For the first time, we investigated the possibility of using non-minimal coupled scalar field (include Real and Complex scalar fields) as the candidate of dark energy---Quintessence or Phantom. A cosmological model droved by real scalar field with accelerating and decelerating, forever cycling and expanding was constructed. Classical and quantum wormholes with Tachyon fields were discussed in detail. The entropy of sphere symmetric black holes due to arbitrary spin fields was studied, and the proportional relations between entropy and fields degeneracy was derived. For the first time, we investigated the neutrino quasinormal modes of stationary black holes in the background of de Sitter space-time, and the quasinormal modes of Schwarzschild black holes with arbitrary spin fields. We also studied the quantum teleportation in the background of curved space-time for the first time.

中文摘要：我们首次研究了非最小耦合标量场作为宇宙暗能量－Quintessence、Phantom的可能性；构造了一个实标量场驱动的加速－减速无限循环，永恒膨胀的宇宙模型；详尽讨论了具有Tachyon场的经典和量子虫洞；研究了一般球对称黑洞缘于任意自旋量子场的熵，给出了熵与量子场简并度之间的正比关系；首次研究了deSitter背景时空下具有中微子场的稳态黑洞的似正规模与具有任意自旋场的Schwarzschild黑洞的似正规模问题；首次研究了弯曲时空背景下的量子通讯问题。

So the electrical conductivity induced by up-spin polarons (down-spin polarons) is different, too.

另外还发现，外电场会增强有机半导体电流的自旋极化率。

Spin injection make the spin density of the polarons different at the different position in the organic semiconductor.

计算结果表明，极化子电导的自旋相关性是自旋注入引起的，和电流的自旋极化率密切相关；在自旋注入发生后，有机半导体内不同位置上极化子自旋态密度不同，由此产生的极化子电导也不相同，极化子电导是位置的函数。

From the calculation, it is found that polarons are the effective spin carriers in spin dependent injection and transport in organic semiconductors.

通过计算发现，极化子为实现有机半导体中电流极化注入和输运的有效自旋载流子，即使它只占总载流子很少一部分。

At low temperature, both the positive and negative magnetoresistance effect can be observed for all the samples. The s-d exchange interaction induced spin-splitting, the formation of bound magnetic polarons, and the magnetic field suppressed spin-disorder scattering were competed for the MR behavior.

另外，在低温时所有样品都表现出较大的正磁电阻，我们认为正磁电阻效应是由于s-d电子交换相互作用引起的自旋劈裂造成的，而高场时出现的负磁电阻效应则可能归因于磁场导致的束缚磁极化子的破损和自旋散射的抑制。

The ratio of electron spin energy to the interaction energy between electron and LO phonon decreases with increasing z, so does the ratio of electron spin energy to the interaction energy between polarons.

电子自旋能量与电子和LO声子之间的相互作用能之比以及与声子之间的相互作用能之比都随z增加而减小。

Conjugated polymers which are different from traditional semiconductor, have some unique properties. Most of them are quasi-one-dimensional systems with strong electron-phonon interaction. Their carriers are composite particles, which are different from simply electron and hole, characterized with the surrounding distortion of lattice configuration (polaron with spin 1/ 2 , bipolaron with spin 0 etc.). The transport of the carriers and the process that oppositely charged polarons combine to from exciton are believed to be of fundamental importance for electroluminescence properties.

共轭聚合物具有不同于传统半导体的特性，它们是强电-声相互作用的准一维体系，其载流子不再是简单的电子和空穴，而是伴随晶格畸变的具有内部结构的复合粒子(自旋1/2的极化子、自旋为0的双极化子等)，这些载流子的输运、以及正负极化子对复合成激子的过程在很大程度上决定着聚合物的电致发光性质。

We conclude that the s-d exchange_interaction_induced spin-splitting gives rise to positive MR, while the formation of bound magnetic polarons and the magnetic field suppressed spin-disorder scattering are responsible for the negative MR behavior under high field.

另外，在低温时所有样品都表现出较大的正磁电阻，认为正磁电阻效应是由于s-d电子交换相互作用引起的自旋劈裂造成的，而高场时出现的负磁电阻效应则可能归因于磁场

But this is impossible, as long as it is engaging in a market economy, there are risks in any operation.

但是，这是不可能的，只要是搞市场经济，是有风险的任何行动。

We're on the same wavelength.
