Abstract: The scattering of conduction electrons off structural two-level systems (TLS) can lead to a non-magnetic two-channel Kondo (2CK) effect, but experimental evidence is rare. In our previous works, we have shown that the remarkable differences… read more here.

Abstract: Materials with non-Kramers doublet ground states naturally manifest the two-channel Kondo effect, as the valence fluctuations are from a non-Kramers doublet ground state to an excited Kramers doublet. Here, the development of a heavy Fermi… read more here.

DOI: 10.1103/t78z-pyfr
Abstract: We demonstrate that a boundary defect in the single spin-$\frac{1}{2}$ quantum $XX$ chain exhibits two-channel Kondo physics. Due to the presence of the defect, the edge spin fractionalizes into two Majorana fermions, out of which… read more here.
