Directional massless Dirac fermions in a layered van der Waals material with one-dimensional long-range order
T. Y. Yang, Q. Wan, D. Y. Yan +13
Exotic properties in single or few layers of van der Waals materials carry great promise for applications in nanoscaled electronics, optoelectronics and flexible devices. The estab…
Bidding Strategy with Forecast Technology Based on Support Vector Machine in Electrcity Market
C. Gao, E. Bompard, R. Napoli +1
The participants of the electricity market concern very much the market price evolution. Various technologies have been developed for price forecast. SVM (Support Vector Machine) h…
Charged bosons made of fermions in a solid state system without Cooper pairing
Z. Sun, J. Beaumariage, Q. Wan +9
We report experimental evidence for charged boson states in a solid without Cooper pairing, based on attaching two free carriers to an exciton in a semiconducting system. Theoretic…
Inherited Weak Topological Insulator Signatures in Topological Hourglass Semimetal Nb3XTe6 (X = Si, Ge)
Q. Wan, T. Y. Yang, S. Li +17
Using spin-resolved and angle-resolved photoemission spectroscopy and first-principles calculations, we have identified bulk band inversion and spin polarized surface state evolved…
Evidence of orbit-selective electronic kagome lattice with planar flat-band in correlated paramagnetic YCr6Ge6
T. Y. Yang, Q. Wan, Y. H. Wang +13
Electronic properties of kagome lattice have drawn great attention recently. In associate with flat-band induced by destructive interference and Dirac cone-type dispersion, abundan…
Observation of multi Dirac fermion cloning induced by moiré potential in graphene-SiC heterostructure
C. L. Wu, Q. Wan, C. Peng +6
We reexamine the electronic structure of graphene on SiC substrate by angle-resolved photoemission spectroscopy. We directly observed multiply cloning of Dirac cone, in addition to…
