Collective excitations from composite orders in Kondo lattice with non-Kramers doublets
Shintaro Hoshino, Yoshio Kuramoto
Goldstone modes emerge associated with spontaneous breakdown of the continuous symmetry in the two-channel Kondo lattice, which describes strongly correlated f-electron systems wit…
Mean-field description of odd-frequency superconductivity with staggered ordering vector
Shintaro Hoshino
A low-energy fixed-point Hamiltonian is constructed for the s-wave odd-frequency pairing state with staggered ordering vector in the two-channel Kondo lattice. The effective model…
Anisotropic Magnetic Response in Kondo Lattice with Antiferromagnetic Order
Taku Kikuchi, Shintaro Hoshino, Yoshio Kuramoto
Magnetic properties are investigated for the Kondo lattice by using the continuous time quantum Monte Colro (CT-QMC) and the dynamical mean field theory (DMFT). The DMFT+CT-QMC app…
Composite Orders and Lifshitz Transition of Heavy Electrons
Yoshio Kuramoto, Shintaro Hoshino
Magnetic and other unconventional electronic orders are discussed for heavy electrons. In addition to the ordinary Kondo lattice, we consider non-Kramers systems taking the two-cha…
