Dimensionality tuning of heavy-fermion states in ultrathin CeSi2 films
Yi Wu, Weifan Zhu, Teng Hua +18
Dimensionality tuning is an important method to modify the electronic states of quantum materials. However, the mechanism of such tuning in heavy fermion systems and its connection…
Pressure-induced superconductivity beyond magnetic quantum criticality in a Kondo ferromagnet
Yanan Zhang, Yongjun Zhang, Jiawen Zhang +13
Quantum phase transitions are an established setting for emergent phenomena driven by strong electronic correlations, including strange metals and unconventional superconductivity.…
Nodeless superconductivity in 4H-TaS with broken time reversal symmetry
Yuwei Zhou, Fanyu Meng, Yanen Huang +7
The transition metal dichalcogenide 4H-TaS exhibits characteristics of topological edge modes and two-component superconductivity with time-reversal symmetry breaking (…
Fermi Surface Nesting with Heavy Quasiparticles in the Locally Noncentrosymmetric Superconductor CeRhAs
Yi Wu, Yongjun Zhang, Sailong Ju +15
The locally noncentrosymmetric heavy fermion superconductor CeRhAs has attracted considerable interests due to its rich superconducting phases, accompanied by a quadrupole…
High-temperature superconductivity with zero-resistance and strange metal behavior in LaNiO
Yanan Zhang, Dajun Su, Yanen Huang +13
Recently signatures of superconductivity were observed close to 80 K in \LN\ under pressure. This discovery positions \LN\ as the first bulk nickelate with high-temperature superco…
