Polytypism and Unexpected Strong Interlayer Coupling of two-Dimensional Layered ReS2
Xiao-Fen Qiao, Jiang-Bin Wu, Lin-Wei Zhou +7
The anisotropic two-dimensional (2D) van der Waals (vdW) layered materials, with both scientific interest and potential application, have one more dimension to tune the properties…
Spin frustration and magnetic ordering in triangular lattice antiferromagnet CaCoNbO
J. Dai, P. Zhou, P. S. Wang +5
We synthesized a quasi-two-dimensional distorted triangular lattice antiferromagnet CaCoNbO, in which the effective spin of Co is 1/2 at low temperatures, whose…
Strong charge density wave fluctuation and sliding state in PdTeI with quasi-1D PdTe chains
Hechang Lei, Kai Liu, Jun-ichi Yamaura +4
In quasi-one-dimensional (quasi-1D) system, the charge density wave (CDW) transition temperature TCDW is usually lower than the mean-field-theory predicted TMF and a CDW fluctuatio…
Flexible Attribute-Based Encryption Applicable to Secure E-Healthcare Records
Bo Qin, Hua Deng, Qianhong Wu +3
In e-healthcare record systems (EHRS), attribute-based encryption (ABE) appears as a natural way to achieve fine-grained access control on health records. Some proposals exploit ke…
Observation of the Efimovian Expansion in Scale Invariant Fermi Gases
Shujin Deng, Zhe-Yu Shi, Pengpeng Diao +4
Scale invariance emerges and plays an important role in strongly correlated many-body systems such as critical regimes nearby phase transitions and the unitary Fermi gases. Discret…
Topological invariants for interacting topological insulators: II. Breakdown of the Green's function formalism
Yuan-Yao He, Han-Qing Wu, Zi Yang Meng +1
Topological phase transitions in free fermion systems can be characterized by closing of single-particle gap and change in topological invariants. However, in the presence of elect…
