标题： Inter-node superconductivity in strained Weyl semimetals

摘要： 应变诱导的赝磁场对外尔半金属中节点间自旋三重态超导态的影响是通过准经典Eilenberger形式主义进行研究的。 发现与赝磁场方向平行的库珀对配对在自旋三重态中具有最低的能量，且其能隙不依赖于磁场的强度。 在这种状态下，电和手征超导电流都不存在。 这与库珀对自旋垂直于磁场的超导态形成对比，后者支持非零的手征电流，并受到应变诱导的赝磁场的抑制。 相应的临界场值被估计出来，该值区分了正常态和超导态。 显示英文摘要

摘要： The effects of a strain-induced pseudomagnetic field on inter-node spin-triplet superconducting states in Weyl semimetals are studied by using the quasiclassical Eilenberger formalism. It is found that the Cooper pairing with spins parallel to the pseudomagnetic field has the lowest energy among the spin-triplet states and its gap does not depend on the strength of the field. In such a state, both electric and chiral superconducting currents are absent. This is in contrast to the superconducting states with the spins of Cooper pairs normal to the field, which support a nonzero chiral current and are inhibited by the strain-induced pseudomagnetic field. The corresponding critical value of the field, which separates the normal and superconducting phases, is estimated.
