Topological Green function of interacting systems
Minh-Tien Tran, Duong-Bo Nguyen, Hong-Son Nguyen +1
We construct a Green function, which can identify the topological nature of interacting systems. It is equivalent to the single-particle Green function of effective non-interacting…
Magnetic competition in topological kagome magnets
Minh-Tien Tran, Duong-Bo Nguyen, Hong-Son Nguyen +1
Magnetic competition in topological kagome magnets is studied by incorporating the spin-orbit coupling, the anisotropic Hund coupling and spin exchange into the kagome lattice. Usi…
Impact of magnetic dopants on magnetic and topological phases in magnetic topological insulators
Thanh-Mai Thi Tran, Duc-Anh Le, Tuan-Minh Pham +2
A topological insulator doped with random magnetic impurities is studied. The system is modelled by the Kane-Mele model with a random spin exchange between conduction electrons and…
Fractionalization of long-range ordered states in a Falicov-Kimball model
Minh-Tien Tran
A Falicov-Kimball model which thermodynamically reduces the local Coulomb interaction of particles to attraction or repulsion is studied within the dynamical mean-field theory. In…
Selective Kondo strong coupling in magnetic impurity flat-band lattices
Duong-Bo Nguyen, Thanh-Mai Thi Tran, Thuy Thi Nguyen +1
The periodic Anderson impurity model on the Lieb lattice is studied by the slave-boson mean-field approximation in the strong interaction limit. The electron structure of conductio…
Molecular Kondo effect in flat-band lattices
Minh-Tien Tran, Thuy Thi Nguyen
The Kondo effect of a single magnetic impurity embedded in the Lieb lattice is studied by the numerical renormalization group. When the band flatness is present in the local densit…
