Spin disorder competing with positional symmetry breaking governs the metal-insulator behavior in oxide paramagnets
Jia-Xin Xiong, Xiuwen Zhang, Alex Zunger
Numerous transition-metal oxides have low-temperature antiferromagnetic (AFM) states and high-temperature paramagnetic (PM) phases, where the AFM state is usually insulating while…

Upward band gap bowing and negative mixing enthalpy in multi-component cubic halide perovskite alloys
Xiuwen Zhang, Fernando P. Sabino, Jia-Xin Xiong +1
Physical properties intermediate between constituents of alloys can be achieved as downward convex positive bowing, upward concave negative bowing, or zero bowing. Such bowing effe…

Matter with apparent and hidden spin physics
Jia-Xin Xiong, Xiuwen Zhang, Lin-Ding Yuan +1
Materials with interesting physical properties are often designed based on our understanding of the target physical effects. The physical properties can be either explicitly observ…
