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…
Pseudogap and Fermi arc induced by Fermi surface nesting in a centrosymmetric skyrmion magnet
Yuyang Dong, Yuto Kinoshita, Masayuki Ochi +12
Skyrmions in noncentrosymmetric materials are believed to occur due to the Dzyaloshinskii-Moriya interaction. By contrast, the skyrmion formation mechanism in centrosymmetric mater…
Room temperature quantum emitters in van der Waals α-MoO3
Jeonghan Lee, Haiyuan Wang, Keun-Yeol Park +6
Quantum emitters in solid-state materials are highly promising building blocks for quantum information processing and communication science. Recently, single-photon emission from v…
