论文摘要
理论上研究了自旋独立杂交电位和旋转轨道偶联对两个带相等导体的旋转轨道耦合的影响。为了研究两个频带超导体中的对称类别，戈尔科夫方程进行了分析求解。通过定义旋转单线和自旋三胞胎S波顺序参数，由于两个带的自由度，研究了库珀对的对称类别。对于旋转单线案例，显示自旋独立杂交生成库珀对属于频率旋转单重，甚至动量均匀的频率平价（ESEE）对称性类别，用于内标和边际配对相关性。对于旋转三重序列参数，内的配对相关性会产生奇数频率自旋三重态甚至动量均匀均衡（otee）对称类别，而频带配对相关性甚至会产生频率旋转三胞胎甚至动量奇数奇数频段奇偶校验ETEO）类。对于旋转单线，自旋轨道耦合会生成属于奇数频率旋转单线奇数动量的配对相关性，甚至频段均衡（OSOE）对称性类别，甚至频率旋转单元，甚至分别用于内键和边际配对相关的频段平均（ESEE）甚至频段奇偶校验（ESEE）。在ITRABAND和带间相关的自旋三重态中，自旋轨道耦合分别产生均匀的旋转三胞胎奇数动量，甚至带频率奇偶元（ETOE），甚至频率旋转三重态甚至动量动量奇数奇数奇偶校验（ETEO）。
The effects of spin independent hybridization potential and spin orbit coupling on two band superconductor with equal time s-wave inter band pairing order parameter is investigated theoretically. To study symmetry classes in two band superconductors the Gorkov equations are solved analytically. By defining spin singlet and spin triplet s wave order parameter due to two band degree of freedom the symmetry classes of Cooper pair are studied. For spin singlet case it is shown that spin independent hybridization generates Cooper pair belongs to even frequency spin singlet even momentum even band parity (ESEE) symmetry class for both intraband and interband pairing correlations. For spin triplet order parameter, intraband pairing correlation generates odd frequency spin triplet even momentum even band parity (OTEE) symmetry class whereas, interband pairing correlation generates even frequency spin triplet even momentum odd band parity ETEO) class. For the spin singlet, spin orbit coupling generates pairing correlation that belongs to odd frequency spin singlet odd momentum even band parity (OSOE) symmetry class and even frequency spin singlet even momentum even band parity (ESEE) for intraband and interband pairing correlation respectively. In the spin triplet case for itraband and interband correlation, spin orbit coupling generates even-frequency spin triplet odd momentum even band parity (ETOE) and even frequency spin triplet even momentum odd band parity (ETEO) respectively.
