Correlated topological band structures of the kagome altermagnets Mn ( Sn, Ge, Ga)
Yingying Cao, Yuanji Xu, Yi-feng Yang
The interplay of topological band structures and electronic correlations may lead to novel quantum phenomena with potential applications. First-principles calculations are critical…
Mechanism of the insulator-to-metal transition and superconductivity in the spin liquid candidate NaYbSe under pressure
Yuanji Xu, Yutao Sheng, Yi-feng Yang
The quantum spin liquid candidate NaYbSe was recently reported to exhibit a Mott transition under pressure. Superconductivity was observed in the high-pressure metallic phase,…
High-energy magnetic excitations from heavy quasiparticles in CeCuSi
Yu Song, Weiyi Wang, Chongde Cao +8
Magnetic fluctuations is the leading candidate for pairing in cuprate, iron-based and heavy fermion superconductors. This view is challenged by the recent discovery of nodeless sup…
Quantum phase transitions and superconductivity in the pressurized heavy-fermion compound CeCuP2
Erjian Cheng, Chuchu Zhu, Tianping Ying +8
The tilted balance among competing interactions can yield a rich variety of ground states of quantum matter. In most Ce-based heavy fermion systems, this can often be qualitatively…
The first-principles research on the role of surface in the heavy fermion compound CeRhSi
Yue-Chao Wang, Yuan-Ji Xu, Yu Liu +6
In the heavy fermion materials, the characteristic energy scales of many exotic strongly correlated phenomena (Kondo effect, magnetic order, superconductivity, etc.) are at milli-e…
Observation of flat bands due to band hybridization in 3d-electron heavy-fermion compound CaCu3Ru4O12
Haijiang Liu, Yingying Cao, Yuanji Xu +7
We report angle-resolved photoemission spectroscopy and first-principles numerical calculations for the band structure evolution of the 3d heavy-fermion compound CaCu3Ru4O12. Below…
Quasi-two-dimensional Fermi surfaces and unitary spin-triplet pairing in the heavy fermion superconductor UTe
Yuanji Xu, Yutao Sheng, Yi-feng Yang
We report first-principles and strongly-correlated calculations of the newly-discovered heavy fermion superconductor UTe. Our analyses reveal three key aspects of its magnetic,…
Realization of Kondo chain in CeCoGa
Kangqiao Cheng, Le Wang, Yuanji Xu +9
We revisited the anisotropy of the heavy-fermion material CeCoGa by measuring the electrical resistivity and magnetic susceptibility along all the principal -,…
Nearly-degenerate and pairing symmetry in the heavy fermion superconductor YbRhSi
Yu Li, Qianqian Wang, Yuanji Xu +2
Recent discovery of superconductivity in YbRhSi has raised particular interest in its pairing mechanism and gap symmetry. Here we propose a phenomenological theory of its s…
Anisotropic hybridization in a new Kondo lattice compound CeCoInGa
Le Wang, Yuanji Xu, Meng Yang +6
We report a detailed and comparative study of the single crystal CeCoInGa in both experiment and theory. Resistivity measurements reveal the typical behavior of Kondo lattice w…
Symmetry-enforced heavy-fermion physics in the quadruple-perovskite CaCu3Ir4O12
Min Liu, Yuanji Xu, Danqing Hu +6
Heavy-fermion materials are mostly rare-earth or actinide intermetallics with very few exceptions in d-electron systems. The physical mechanism for these d-electron heavy fermion s…
First-principles calculations of the magnetic and electronic structures of MnP under pressure
Yuanji Xu, Min Liu, Ping Zheng +5
Manganese monophosphide (MnP) shows complicated magnetic states varying with both temperature and pressure. We calculate the magnetic and electronic structures of MnP at different…
