Giant superconducting fluctuations in the compensated semimetal FeSe at the BCS-BEC crossover
S. Kasahara, T. Yamashita, A. Shi +12
The physics of the crossover between weak-coupling Bardeen-Cooper-Schrieffer (BCS) and strong-coupling Bose-Einstein-condensate (BEC) limits gives a unified framework of quantum bo…
Evolution of quasiparticle excitations with critical mass enhancement in superconducting AFe2As2 (A = K, Rb, and Cs)
Y. Mizukami, Y. Kawamoto, Y. Shimoyama +8
In the heavily hole-doped iron-based superconductors FeAs ( K, Rb, and Cs), the electron effective mass increases rapidly with alkali-ion radius. To study how the ma…
Thermal conductivity of quantum magnetic monopoles in the frustrated pyrochlore Yb2Ti2O7
Y. Tokiwa, T. Yamashita, M. Udagawa +8
We report low-temperature thermal conductivity of pyrochlore YbTiO, which contains frustrated spin-ice correlations with significant quantum fluctuations. In the di…
Colossal thermomagnetic response in the exotic superconductor URu2Si2
T. Yamashita, Y. Shimoyama, Y. Haga +8
When a superconductor is heated above its critical temperature , macroscopic coherence vanishes, leaving behind droplets of thermally fluctuating Cooper pair. This superconduc…
Field-induced superconducting phase of FeSe in the BCS-BEC cross-over
S. Kasahara, T. Watashige, T. Hanaguri +13
Fermi systems in the crossover regime between weakly coupled Bardeen-Cooper-Schrieffer (BCS) and strongly coupled Bose-Einstein-condensate (BEC) limits are among the most fascinati…
