Author(s): K. Hattori and H. Tsunetsugu We investigate a four-impurity Anderson model where localized orbitals are located at vertices of a regular tetrahedron and find a novel fixed point in addition to the ordinary Fermi liquid phase. That is characterized by unscreened scalar chirality of a tetrahedron. In this phase, parafermions emer... [Phys. Rev. B 86, 054421] Published Wed Aug 15, 2012
