Topological orbital superfluid with chiral d-wave order in a rotating optical lattice
Ningning Hao, Huaiming Guo, Ping Zhang
Topological superfluid is an exotic state of quantum matter that possesses a nodeless superfluid gap in the bulk and Andreev edge modes at the boundary of a finite system. Here, we…
Topological crystalline antiferromagnetic state in tetragonal FeS
Ningning Hao, Fawei Zheng, Ping Zhang +1
Integration between magnetism and topology is an exotic phenomenon in condensed-matter physics. Here, we propose an exotic phase named topological crystalline antiferromagnetic sta…
Symmetry-protected topological phase in a one-dimensional correlated bosonic model with a synthetic spin-orbit coupling
Jize Zhao, Shijie Hu, Ping Zhang
By performing large-scale density-matrix renormalization group simulations, we investigate a one-dimensional correlated bosonic lattice model with a synthetic spin-orbit coupling r…
Anisotropic Fabry-Pérot resonant states confined within nano-steps on the topological insulator surface
Zhen-Guo Fu, Ping Zhang, Mu Chen +3
The peculiar nature of topological surface states, such as absence of backscattering, weak anti-localization, and quantum anomalous Hall effect, has been demonstrated mainly in bul…
Critical behavior of the energy gap and its relation with the Berry phase close to the excited state quantum phase transition in the Lipkin model
Zi-Gang Yuan, Ping Zhang, Shu-Shen Li
In our previous work [Phys. Rev. A \textbf{85}, 044102 (2012)], we have studied the Berry phase of the ground state and exited states in the Lipkin model. In this paper, using Hell…
Decoherence of a quantum system coupled to an XY spin chain: Role of the initial state of the spin chain
Zi-Gang Yuan, Ping Zhang, Shu-Shen Li
We study the decoherence of a coupled quantum system consisting of a central spin and its correlated environment described by a general spin-chain model. We make it clear that…
