| 英文摘要 | The periodic Anderson lattice model for the crystalline electric field (CEF) split 4f quartet states is used to describe the Yb-based Kondo insulators. In the slave-boson mean-field approximation, we derive the hybridized quasiparticle bands, and surprisingly find that decreasing the hybridization difference of the two CEF quartets may induce a continuous insulator-to-metal phase transition. The resulting metallic phase has a hole and an electron Fermi pocket. Such a phase transition may be realized experimentally by applying pressure, reducing the difference in hybridization of the two CEF quartets in real materials. Copyright (C) EPLA, 2010 |
