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…

Superconducting coherence boosted by outer-layer metallic screening in multilayered cuprates
Junhyeok Jeong, Kifu Kurokawa, Shiro Sakai +13
In multilayered high-Tc cuprates with three or more CuO2 layers per unit cell, the inner CuO2 planes (IPs) are spatially separated from the dopant layers and thus remain cleaner th…
