Anharmonicity and Charge-Noise Sensitivity of Fraunhofer Qubit
Longyu Ma, Tony Liu, Javad Shabani +3
We present a theory of a flux-tunable superconducting qubit, the "Fraunhofer qubit," based on the Fraunhofer interference in a wide ballistic Josephson junction. As magnetic flux t…
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…
Quenched Fe Moment in the Collapsed Tetragonal Phase of CaPrFeAs
Long Ma, G. F. Ji, J. Dai +3
We report As NMR studies on single crystals of rare-earth doped iron pnictides superconductor CaPrFeAs (=0.075 and 0.15). The As spectra…
NMR study of superconductivity and spin fluctuations in hole-doped superconductor Ca1-xNaxFe2As2 (Tc =32 K)
Long Ma, J. S. Zhang, D. M. Wang +4
We report both 23Na and 75As NMR studies on hole-doped Ca1-xNaxFe2As2 superconducting single crystals (x\approx 0.67) with Tc =32 K. Singlet superconductivity is suggested by a sha…
77Se NMR study of pairing symmetry and spin dynamics in KyFe2-xSe2
Weiqiang Yu, L. Ma, J. B. He +4
We present a 77Se NMR study of the newly discovered iron selenide superconductor KyFe2-xSe2, in which Tc = 32 K. Below Tc, the Knight shift 77K drops sharply with temperature, prov…
