聚二苯分子中基态结构的稳定性及各种凝聚相

STABILITY OF GROUND STATE AND CONDENSED PHASES IN INFINITE POLYACENACENE

本文利用统计物理中量子场论方法分析无限长聚二苯分子(Polyacenacene)基态结构的稳定性问题。在无规周相近似(RPA)范围内得到各种有序相:电荷密度波(CDW)、自旋密度波(SDW)及超导相存在的可能性,指出发生这些相变的条件。从而从理论上表明,聚二苯分子在适当条件下有可能成为一种有希望的高温超导体。

The normal ground state stability of infinite polyacenacene is investigated by means of the method of quantum field theory in statistical physics. The condensed phases such as charge density wave (CDW), spin density wave (SDV) and superconducting phases are predicted within the random phase approximation (RPA). In particular, we show that there is a possibility that polyacenacene could be a high temperature superconductor.
