Generating Many Majorana Modes via Periodic Driving: A Superconductor Model
Qing-Jun Tong, Jun-Hong An, Jiangbin Gong +2
Realizing Majorana modes (MMs) in condensed-matter systems is of vast experimental and theoretical interests, and some signatures of MMs have been measured already. To facilitate f…
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…
Anomalous decoherence in a dissipative two-level system
Hai-Bin Liu, Jun-Hong An, Chong Chen +3
We study systematically the non-Markovian decoherence dynamics of a dissipative two-level system, i.e., the so-called spin-boson model. It is interesting to find that the decoheren…
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…
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…
A note on path integral formulism of slave-spin representation of Hubbard model
Yin Zhong, Hong-Gang Luo
This is a note on the derivation of path integral formulism for slave-spin representation of Hubbard model and may be helpful for further study in related works. We are rat…
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…
Inhomogeneity of the phase space of the damped harmonic oscillator under Levy noise
Zhan Cao, Yu-Feng Wang, Hong-Gang Luo
The damped harmonic oscillator under symmetric Lévy white noise shows inhomogeneous phase space, which is in contrast to the homogeneous one of the same oscillator under the Gaussi…
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…
