Selective Kondo screening and strange metallicity by sliding Dirac semimetals
Hanting Zhong, Shuxiang Yang, Chao Cao +2
Kondo screening of local moments in normal metals typically leads to hybridized conduction and valence bands separated by a Kondo gap, resulting in an insulating state at half-band…
Coherent state path integral approach to correlated electron systems with deformed Hubbard operators: from Fermi liquid to Mott insulator
Xiao-Yong Feng, Jianhui Dai
In strongly correlated electron systems the constraint which prohibits the double electron occupation at local sites can be realized by either the infinite Coulomb interaction or t…
Dirac-Kondo semimetals and topological Kondo insulators in the dilute carrier limit
Xiao-Yong Feng, Hanting Zhong, Jianhui Dai +1
Heavy fermion systems contain not only strong electron correlations, which promote a rich set of quantum phases, but also a large spin-orbit coupling, which tends to endow the elec…
Reduced Dimensionality and Magnetic Frustration in KCrAs
Chao Cao, Hao Jiang, Xiao-Yong Feng +1
We study the electronic and magnetic structures of the newly-discovered compound KCrAs. The non-magnetic state has five Fermi surface sheets involving respectively three qu…
Local Kondo entanglement and its breakdown in an effective two-impurity Kondo model
Yuxiang Li, Xiao-Yong Feng, Jianhui Dai
Competition between the Kondo effect and Ruderman-Kittel-Kasuya-Yosida interaction in the two-impurity Kondo problem can be phenomenologically described by the Rasul-Schlottmann sp…
Formation of Molecular-Orbital Bands in a Twisted Hubbard Tube: Implications for Unconventional Superconductivity in K2Cr3As3
Hanting Zhong, Xiao-Yong Feng, Hua Chen +1
We study a twisted Hubbard tube modeling the [CrAs] structure of quasi-one-dimensional superconductors A2Cr3As3 (A = K, Rb, Cs). The molecular-orbital bands emerging from the quasi…
