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…
Kondo scenario of the γ-α phase transition in single crystalline Cerium thin films
Xie-Gang Zhu, Yu Liu, Ya-Wen Zhao +17
The physical mechanism driving the - phase transition of face-centre-cubic (fcc) cerium (Ce) remains controversial until now. In this work, high quality single crystalline fc…
Spin-Triplet Excitonic Insulator: The Case of Graphone
Zeyu Jiang, Wenkai Lou, Yu Liu +5
While various excitonic insulators have been studied in the literature, due to the perceived too-small spin splitting, spin-triplet excitonic insulator is rare. In two-dimensional…
Valence transition in topological Kondo insulator
Jia-Tao Zhuang, Xiao-Jun Zheng, Zhi-Yong Wang +4
We investigate the valence transition in three-dimensional topological Kondo insulator through slave-boson analysis of periodic Anderson model. By including the effect of intra-ato…
Magnetic and topological transitions in three-dimensional topological Kondo insulator
Huan Li, Zhi-Yong Wang, Xiao-Jun Zheng +2
By using an extended slave-boson method, we draw a global phase diagram summarizing both magnetic phases and paramagnetic (PM) topological insulating phases (TI) in three-dimen…
ARPES/STM study of the surface terminations and 5-electron character in URuSi
W. Zhang, H. Y. Lu, D. H. Xie +9
Hidden order in URuSi has remained a mystery now entering its 4th decade. The importance of resolving the nature of the hidden order has stimulated extensive research. Here…
