Possible pairing states in the superconducting bilayer nickelate
Dheeraj Kumar Singh, Garima Goyal, Yunkyu Bang
We examine various possibilities for the pairing mechanisms in the recently discovered bilayer-nickelate superconductor within the Bardeen-Cooper-Schrieffer framework. Unlike earli…
Origin of the large differences in high-pressure stability and superconductivity between ThH9 and ThH18
Shichang Yao, Chongze Wang, Hyunsoo Jeon +5
Recently, the thorium hydride ThH9 possessing an H-rich clathrate structure has been experimentally synthesized to exhibit a superconducting transition temperature Tc of 146 K at 1…
Fermi arcs and pseudogap phase in a minimal microscopic model of -wave superconductivity
Dheeraj Kumar Singh, Samrat Kadge, Yunkyu Bang +1
We show conclusively that a pseudogap state can arise at , for reasonable pairing interaction strength, from order parameter fluctuations in a two dimensional minimal mode…
Electron-phonon coupling and superconductivity in an alkaline earth hydride CaH at high pressures
Hyunsoo Jeon, Chongze Wang, Shuyuan Liu +3
Recently, an alkaline earth hydride CaH having a sodalitelike clathrate structure has been experimentally synthesized at megabar pressures with a maximum of 215 K, compar…
phonon anomaly driven by Fermi surface instability at intermediate temperature in YBaCuO
Dongjin Oh, Dongjoon Song, Younsik Kim +5
We performed temperature- and doping-dependent high-resolution Raman spectroscopy experiments on YBaCuO to study phonons. The temperature dependence…
Hole-Doping Effect on Superconductivity in Compressed CeH at High Pressure
Chongze Wang, Shuyuan Liu, Hyunsoo Jeon +3
The experimental realization of high-temperature superconductivity in compressed hydrides HS and LaH at high pressures over 150 GPa has aroused great interest in reducin…
