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…
Conventional s-wave superconductivity in BiS2-based NdO0.71F0.29BiS2 revealed by thermal transport measurements
T. Yamashita, Y. Tokiwa, D. Terazawa +5
To study the superconducting gap structure of BiS-based layered compound NdOFBiS ( = 5 K), we measured the thermal conductivity , which…
Dichotomy between the hole and electrons behavior in the multiband FeSe probed by ultra high magnetic fields
M. D. Watson, T. Yamashita, S. Kasahara +15
Magnetoresistivity \r{ho}xx and Hall resistivity \r{ho}xy in ultra high magnetic fields up to 88T are measured down to 0.15K to clarify the multiband electronic structure in high-q…
Fermi surface of IrTe2 in the valence-bond state as determined by quantum oscillations
S. F. Blake, M. D. Watson, A. McCollam +11
We report the observation of the de Haas-van Alphen effect in IrTe2 measured using torque magnetometry at low temperatures down to 0.4 K and in high magnetic fields up to 33T. IrTe…
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…
Novel features of Josephson flux-flow in Bi-2212: contribution of in-plane dissipation, coherent response to mm-wave radiation, size effect
Yu. I. Latyshev, A. E. Koshelev, V. N. Pavlenko +3
We studied Josephson flux-flow (JFF) in Bi-2212 stacks fabricated from single crystal whiskers by focused ion beam technique. For long junctions with the in-plane sizes 30 x 2 (mu)…
