平衡和非平衡全息s+p超导体中的混沌
Chaos in balanced and unbalanced holographic s+p superconductors
摘要:
在这项工作中,我们提出了一个玩具模型的混合物的超导体竞争的s和p模式使用规范/重力对偶。我们证明,该模型进行相变与适当的选择不同的化学势值。我们考虑平衡和不平衡的情况。我们提出高温超导体混合s+p相的体模型中的凝聚场经历混沌相空间方案。使用一个合适的测度函数的混沌,我们证明了混沌动力学的存在,通过凝聚场。作为另一种方法,我们还研究了凝聚体在扩展相空间中的相图。
英文摘要:
In this work, we propose a toy model for a mixture of superconductors with competitive s and p modes using gauge/gravity duality. We demonstrate that the model undergoes phase transitions with the proper choice of different values for chemical potentials. We consider both balanced and unbalanced cases. We propose that the condensate field in the bulk toy model for a mixing s+p phase of high temperature superconductors undergoes a chaotic phase space scenario. Using a suitable measure function for chaos, we demonstrate the existence of chaotic dynamics via condensate fields. As an alternative method, we also investigate the phase portrait in the extended phase space for the condensates.
