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 $T_{2}$ $C h_{2}$ $P n$ , 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

Ba $_{8}$ CoNb $_{6}$ O $_{24}$ presents a system whose Co $^{2 +}$ 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…
