Yoshimori-Kasai Model Phase Diagram and Naniwa Series for Quantum Dynamics

We present the phase diagram of heavy fermions system (HFS) and muon adsorption calculations on Pd (111) surface. HFS undergoes phase transitions from Fermi liquid (FL) to non-Fermi liquid (NFL). Furthermore, antiferromagnetic (AF), spin-density wave (SDW)and superconductivity can be realized by changing electron densities and temperature. It is shown that at upper Hubbard band filling, HFS changes phase from antiferromagnetic to superconducting at low temperatures. Furthermore, in an attempt to elucidate muon dynamics on surfaces and subsurfaces, we show thatmuon exhibits tunneling effects independent of surface vibrations from quantum dynamical calculations. The results shown herein may have important implications on future ultra-slow muon experiments.
