Discovery of Emergent Photon and Monopoles in a Quantum Spin Liquid
Y. Tokiwa, T. Yamashita, D. Terazawa +10
Quantum spin liquid (QSL) is an exotic quantum phase of matter whose ground state is quantum-mechanically entangled without any magnetic ordering. A central issue concerns emergent…
Fully gapped superconductivity with no sign change in the prototypical heavy-fermion CeCu2Si2
T. Yamashita, T. Takenaka, Y. Tokiwa +16
In exotic superconductors including high- copper-oxides, the interactions mediating electron Cooper-pairing are widely considered to have a magnetic rather than the convention…
Evolution of the Fermi surface of the nematic superconductors FeSe1-xSx
A. I. Coldea, S. F. Blake, S. Kasahara +13
We investigate the evolution of the Fermi surfaces and electronic interactions across the nematic phase transition in single crystals of FeSe1-xSx using Shubnikov-de Haas oscillati…
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…
Quasiparticle Excitations in the Superconducting State of FeSe Probed by Thermal Hall Conductivity in the Vicinity of the BCS-BEC Crossover
Tatsuya Watashige, Stevan Arsenijević, Takuya Yamashita +10
There is growing evidence that the superconducting semimetal FeSe ( K) is in the crossover regime between weak-coupling Bardeen-Cooper-Schrieffer (BCS) and strong-couplin…
