Emergent p-Wave Kondo Coupling in Multi-Orbital Bands with Mirror Symmetry Breaking

Kondo effect in the periodic Anderson model is examined for situations where the conduction bands are of multiorbital character and subject to mirror-symmetry-breaking electric field. Taking p-orbital-based model for analysis, we find that a new hybridization channel opens up between p-orbital electrons and the local moments, leading to Kondocoupled phases with nematic, or two-fold symmetry, although the microscopic Hamiltonian has the full square symmetry. The reduced symmetry in the band structure should be readily observable in spectroscopic or transport measurements for heavy fermion system in a multilayer environment such as successfully grown recently.
