Anomalous superfluid density in quantum critical superconductors
K. Hashimoto, Y. Mizukami, R. Katsumata +10
When a second-order magnetic phase transition is tuned to zero temperature by a non-thermal parameter, quantum fluctuations are critically enhanced, often leading to the emergence…
A Sharp Peak of the Zero-Temperature Penetration Depth at Optimal Composition in BaFe2(As1-xPx)2
K. Hashimoto, K. Cho, T. Shibauchi +14
In a superconductor, the ratio of the carrier density, , to their effective mass, , is a fundamental property directly reflecting the length scale of the superfluid flow, t…
Nodeless vs nodal order parameters in LiFeAs and LiFeP superconductors
K. Hashimoto, S. Kasahara, R. Katsumata +7
High-precision measurements of magnetic penetration depth in clean single crystals of LiFeAs and LiFeP superconductors reveal contrasting low-energy quasiparticle excitations.…
Evidence for superconducting gap nodes in the zone-centered hole bands of KFe2As2 from magnetic penetration-depth measurements
K. Hashimoto, A. Serafin, S. Tonegawa +13
Among the iron-based pnictide superconductors the material KFeAs is unusual in that its Fermi surface does not consist of quasi-nested electron and hole pockets. Here we re…
