BCS-BEC crossover driven by small Fermi pockets of a high-Tc cuprate superconductor
Junhyeok Jeong, Yamato Enomoto, Yoshimitsu Kohama +16
Fermi arcs observed in underdoped cuprates have sparked debate over whether they represent segments of a large Fermi surface or small Fermi pockets. This ambiguity has long hindere…

High-Field Torque Magnetometry on the Kagome Antiferromagnet Karpenkoite
Hibiki Kunisawa, Ryuya Watanabe, Jun-ichi Yamaura +2
We report torque magnetometry results on single crystals of karpenkoite Co3(V2O7)(OH)2 2H2O, a model candidate for the kagome antiferromagnet. No field-induced phase transition is…
