Converting topological insulators into topological metals within the tetradymite family
K. -W. Chen, N. Aryal, J. Dai +14
We report the electronic band structures and concomitant Fermi surfaces for a family of exfoliable tetradymite compounds with the formula , obtained as a modificatio…
Mermin-Wagner physics, (H,T) phase diagram, and candidate quantum spin-liquid phase in the spin-1/2 triangular-lattice antiferromagnet Ba8CoNb6O24
Y. Cui, J. Dai, P. Zhou +11
BaCoNbO presents a system whose Co ions have an effective spin 1/2 and construct a regular triangular-lattice antiferromagnet (TLAFM) with a very large interl…
Experimental Approach to the Thermodynamics of the Pure Two-Dimensional Spin-1/2 Triangular Lattice Antiferromagnet in Ba8CoNb6O24
Y. Cui, J. Dai, P. Zhou +10
Frustrated quantum magnets pose well-defined questions concerning quantum fluctuation effects and the nature of the many-body wavefunction, which challenge theory, numerics, experi…
Nearly-critical spin and charge fluctuations in KFe2As2 observed by high-pressure NMR
P. S. Wang, P. Zhou, J. Dai +7
We report a high-pressure 75As NMR study on the heavily hole-doped iron pnictide superconductor KFe2As2 (Tc~3.8 K). The low-energy spin fluctuations are found to decrease with appl…
Near field thermal memory device
S. A. Dyakov, J. Dai, M. Yan +1
We report the concept of a near-field memory device based on the radiative bistability effect in the system of two closely separated parallel plates of SiO and VO which exc…
Spin Fluctuations and Frustrated Magnetism in the Multiferroic FeVO
J. Zhang, L. Ma, J. Dai +4
We report V nuclear magnetic resonance (NMR) studies on single crystals of the multiferroic material FeVO. The high-temperature Knight shift shows Curie-Weiss behavior,…
Orbital selective correlations between nesting/scattering/Lifshitz transition and the superconductivity in AFe1-xCoxAs (A=Li, Na)
Z. R. Ye, Y. Zhang, M. Xu +9
The correlations between the superconductivity in iron pnictides and their electronic structures are elusive and controversial so far. Here through angle-resolved photoemission spe…
Robust magnetic order of Ce 4f-electrons coexisting with superconductivity in CeFeAsOF
T. Shang, L. Jiao, J. Dai +4
The electrical resistance of CeFeAsOF (x = 0.06 and 0.08) has been measured in a magnetic field up to 40T. At zero field, the sample with x = 0.06 shows a structural ph…
