Pairing symmetry of heavy fermion superconductivity in the two-dimensional Kondo-Heisenberg lattice model
Yu Liu, Guang-Ming Zhang, Lu Yu
In the two-dimensional Kondo-Heisenberg lattice model away from half-filled, the local antiferromagnetic exchange coupling can provide the pairing mechanism of quasiparticles via t…
Weak ferromagnetism with the Kondo screening effect in the Kondo lattice systems
Yu Liu, Guang-Ming Zhang, Lu Yu
We carefully consider the interplay between ferromagnetism and the Kondo screening effect in the conventional Kondo lattice systems at finite temperatures. Within an effective mean…
Multiple Lifshitz transitions driven by short-range antiferromagnetic correlations in the two-dimensional Kondo lattice model
Yu Liu, Guang-Ming Zhang
With a mean field approach, the heavy Fermi liquid in the two-dimensional Kondo lattice model is carefully considered in the presence of short-range antiferromagnetic correlations.…
Vacuum induced Berry phases in single-mode Jaynes-Cummings models
Yu Liu, L. F. Wei, W. Z. Jia +1
Motivated by the work [Phys. Rev. Lett. 89, 220404 (2002)] for detecting the vacuum-induced Berry phases with two-mode Jaynes-Cummings models (JCMs), we show here that, for a param…
