Heavy fermion phase diagram in magic-angle twisted trilayer graphene
Le Zhang, Wenqiang Zhou, Xinjie Fang +5
The interplay between localized magnetic moments and itinerant electrons gives rise to exotic quantum states in condensed matter systems. Here, we demonstrate an electrically tunab…
Superconductivity under pressure in the two-dimensional van der Waals heavy-fermion metal CeSiI
Tong Shi, Wenhao Li, Qingxin Dong +10
CeSiI is a newly discovered exfoliable van der Waals (vdW) heavy-fermion metal featured by a long-range antiferromagnetic (AF) order (TN =7.5 K) inside the Kondo coherent state bel…
Emergent superconducting stripes in two-orbital superconductors
Qiong Qin, Yi-feng Yang
Motivated by recent experiments in KTaO/EuO interface, we propose an intrinsic mechanism where superconducting stripes emerge naturally without involving disorder, charge inhom…
Fermi liquid and isotropic superconductivity of Hund scenario for bilayer nickelates
Jiangfan Wang, Yi-feng Yang
Recent experiments on bulk and thin film bilayer nickelate high- superconductors urge for clarification of their pairing mechanism. Debates exist on whether the hybridization…
Intrinsic constraint on for unconventional superconductivity
Qiong Qin, Yi-feng Yang
Can room temperature superconductivity be achieved in correlated materials under ambient pressure? Our answer to this billion-dollar question is probably no, at least for realistic…
