Abstract
We examine Kondo effect in the periodic Anderson model for which the conduction band is of multi-orbital character and subject to mirror symmetry breaking field imposed externally. Taking p-orbital-based toy model for analysis, we find the Kondo pairing symmetry of p-wave character emerges self-consistently over some regions of parameter space and filling factor even though only the on-site Kondo hybridization is assumed in the microscopic Hamiltonian. The band structure in the Kondo-hybridized phase becomes nematic, with only two-fold symmetry, due to the p-wave Kondo coupling. The reduced symmetry should be readily observable in spectroscopic or transport measurements for heavy fermion system in a multilayer environment such as successfully grown recently.
