Evidence for a square-square vortex lattice transition in a high- cuprate superconductor
D. J. Campbell, M. Frachet, S. Benhabib +10
Using sound velocity and attenuation measurements in high magnetic fields, we identify a new transition in the vortex lattice state of LaSrCuO (LSCO). The transit…
Quasiparticle on Bogoliubov Fermi Surface and Odd-Frequency Cooper Pair
Dakyeong Kim, Shingo Kobayashi, Yasuhiro Asano
We discuss a close relationship between a quasiparticle on the Bogoliubov Fermi surface and an odd-frequency Cooper pair in a superconductor in which a Cooper pair consisting of tw…
Theoretical insights into electronic nematic order, bond-charge orders, and plasmons in cuprate superconductors
Hiroyuki Yamase
In this article, we focus on the charge degree of freedom in cuprate superconductors and review theoretical insights into the electronic nematic order, bond-charge orders, and plas…
Fluorine solubility and superconducting properties of Sm(O,F)BiS single crystals
Koki Kinami, Yuji Hanada, Masanori Nagao +5
Sm(O,F)BiS2 superconducting single crystals with various nominal F contents have been grown using KI-KCl flux. The solid solution limit of F at the O-site in Sm(O,F)BiS2 single cry…
Thermodynamic evidence for the formation of a Fulde-Ferrell-Larkin-Ovchinnikov phase in the organic superconductor -(BETS)GaCl
Shusaku Imajo, Takuya Kobayashi, Atsushi Kawamoto +2
In this work, the thermodynamic properties of the organic superconductor -(BETS)GaCl are investigated to study a high-field superconducting state known as the putative F…
Fermi surface in La-based cuprate superconductors from Compton scattering imaging
Hiroyuki Yamase, Yoshiharu Sakurai, Masaki Fujita +2
Compton scattering provides invaluable information on the underlying Fermi surface (FS) and is a powerful tool complementary to angle-resolved photoemission spectroscopy and quantu…
