1D Hubbard model elementary objects scattering

J. M. P. Carmelo, P. D. Sacramento

In terms of electron processes, the 1D Hubbard model is a nonperturbative problem. That renders the description in terms of electron scattering of the microscopic processes that co…

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…

Absence of finite-temperature ballistic charge transport in the 1D half-filled Hubbard model

J. M. P. Carmelo, Shi-Jian Gu

Finite-temperature T>0 transport properties of integrable and nonintegrable one-dimensional (1D) many-particle quantum systems are rather different, showing in the metallic phases…

Half-filled Kondo lattice on the honeycomb lattice

Yin Zhong, Ke Liu, Yu-Feng Wang +2

The unique linear density of state around the Dirac points for the honeycomb lattice brings much novel features in strongly correlated models. Here we study the ground-state phase…

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…

Hierarchy of fractional Chern insulators and competing compressible states

A. M. Läuchli, Z. Liu, E. J. Bergholtz +1

We study the phase diagram of interacting electrons in a dispersionless Chern band as a function of their filling. We find hierarchy multiplets of incompressible states at fillings…

Quantum Monte Carlo Study of Pairing Symmetry and Correlation in Iron-based Superconductors

Tianxing Ma, Hai-Qing Lin, Jiangping Hu

We perform a systematic quantum Monte Carlo study of the pairing correlation in the symmetric microscopic model for iron-based superconductors. It is found that the pairing w…

Fractional Chern Insulators in Topological Flat bands with Higher Chern Number

Zhao Liu, Emil J. Bergholtz, Heng Fan +1

Lattice models forming bands with higher Chern number offer an intriguing possibility for new phases of matter with no analogue in continuum Landau levels. Here, we establish the e…

Correlated metallic state in honeycomb lattice: Orthogonal Dirac semimetal

Yin Zhong, Ke Liu, Yong-Qiang Wang +1

A novel gapped metallic state coined orthogonal Dirac semimetal is proposed in the honeycomb lattice in terms of slave-spin representation of Hubbard model. This state corr…

Compensation effect in carbon nanotube quantum dots coupled to polarized electrodes in the presence of spin-orbit coupling

Lin Li, Yang-Yang Ni, Tie-Feng Fang +1

We study theoretically the Kondo effect in carbon nanotube quantum dot attached to polarized electrodes. Since both spin and orbit degrees of freedom are involved in such a system,…

Kondo effect of an adatom in graphene and its scanning tunneling spectroscopy

Lin Li, Yang-Yang Ni, Yin Zhong +2

We study the Kondo effect of a single magnetic adatom on the surface of graphene. It was shown that the unique linear dispersion relation near the Dirac points in graphene makes it…

Alternative Kondo breakdown mechanism: Orbital-selective orthogonal metal transition

Yin Zhong, Ke Liu, Yong-Qiang Wang +1

In a recent paper of Nandkishore and Senthil [arxiv:1201.5998 (2012)], a concept of orthogonal metal has been introduced to reinterpret the disordered state of slave-spin represent…

A General Mechanism for Orbital Selective Phase Transitions

Yu-Zhong Zhang, Hunpyo Lee, Hai-Qing Lin +3

Based on the analysis of a two-orbital Hubbard model within a mean-field approach, we propose a mechanism for an orbital selective phase transition (OSPT) where coexistence of loca…
