Field-induced double dome and Bose-Einstein condensation in the crossing quantum spin chain system AgVOAsO4
Franziska Weickert, Adam A. Aczel, Matthew B. Stone +11
We present inelastic neutron scattering data on the quantum paramagnet AgVOAsO4 that establish the system is a S=1/2 alternating spin chain compound and provide a direct measuremen…
Composition dependence of bulk superconductivity in YFe2Ge2
Jiasheng Chen, Monika B. Gamza, Konstantin Semeniuk +1
In the layered iron-based superconductor YFe2Ge2, a high Sommerfeld ratio of ~100 mJ/molK^2 and a T^(3/2) temperature dependence of the electrical resistivity at low temperature T…
Experimental Determination of the Fermi Surface of Sr3Ir4Sn13
Xiaoye Chen, Swee K. Goh, David A. Tompsett +11
The stannide family of materials A3T4Sn13 (A = La,Sr,Ca, T = Ir,Rh) is interesting due to the interplay between a tunable lattice instability and phonon-mediated superconductivity…
Large Fermi Surface of Heavy Electrons at the Border of Mott Insulating State in NiS2
S. Friedemann, H. Chang, M. B. Gamża +7
One of the early triumphs of quantum physics is the explanation why some materials are metallic whereas others are insulating. While a treatment based on single electron states cor…
