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…
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…
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…
