Orthogonal Dirac semimetal on honeycomb lattice and the electron spectral function in orthogonal metallic states
Yin Zhong, Hong-Gang Luo
Recently, a concept of orthogonal metal has been introduced to reinterpret the disordered state of slave-spin representation in the Hubbard model as an exotic gapped metallic state…
Charge and Spin Fractionalization Beyond the Luttinger Liquid Paradigm
A. Moreno, A. Muramatsu, J. M. P. Carmelo
It is well established that at low energies one-dimensional (1D) fermionic systems are described by the Luttinger liquid (LL) theory, that predicts phenomena like spin-charge separ…
Topological antiferromagnetic spin-density-wave phase in an extended Kondo lattice model
Yin Zhong, Yu-Feng Wang, Yong-Qiang Wang +1
By using an extended mean-field theory, we study the phase diagram of the topological Kondo lattice model on the honeycomb lattice at half-filling in which the conduction electrons…
From fractional Chern insulators to Abelian and non-Abelian fractional quantum Hall states: adiabatic continuity and orbital entanglement spectrum
Zhao Liu, Emil J. Bergholtz
The possibility of realizing lattice analogs of fractional quantum Hall (FQH) states, so-called fractional Chern insulators (FCIs), in nearly flat topological (Chern) bands has att…
Change of an insulator's topological properties by a Hubbard interaction
Miguel A. N. Araújo, Eduardo V. Castro, Pedro D. Sacramento
We introduce two dimensional fermionic band models with two orbitals per lattice site, or one spinful orbital, and which have a non-zero topological Chern number that can be change…
Magnetic Impurities in Graphene
F. M. Hu, Tianxing Ma, Hai-Qing Lin +1
We used a quantum Monte Carlo method to study the magnetic impurity adatoms on graphene. We found that by tuning the chemical potential we could switch the values of the impurity's…
