Transverse magnetic field and chiral-nonchiral transition in vortex states for nearly B//ab in chiral p-wave superconductors

摘要:

基于Eilenberger理论,我们研究了具有大的ab和c各向异性比的手征p波超导体(如Sr_2RuO_4)在几乎平行于ab平面施加磁场时的涡旋态.我们定量地估计了对势、磁化强度和磁通线晶格形状因子的场依赖性,并研究了从低场手征p_-态到高场非手征p_y态的转变.即使是完全平行于ab平面的场,手征态中也存在横向场。当磁场取向与ab平面的夹角在1度以内时,手性-非手性转变消失。这可能是实验检测这种转变很困难的原因。

英文摘要:

On the basis of Eilenberger theory, we study the vortex state when a magnetic field is applied nearly parallel to the ab plane in a chiral p-wave superconductor with a large anisotropy ratio of ab and c, as in Sr2RuO4. We quantitatively estimate the field dependence of the pair potential, magnetization, and flux line lattice form factor, and study the transition from the chiral p_- state at low fields to the nonchiral p_y state at high fields. Even for exactly parallel fields to the ab plane, transverse fields exist in the chiral state. The chiral-nonchiral transition disappears when the magnetic field orientation is tilted within 1 degree from the ab plane. This may be a reason why the experimental detection of this transition is difficult.
