Electronic properties of nickelate superconductor R3Ni2O7 with oxygen vacancies
Xuelei Sui, Xiangru Han, Xiaojun Chen +3
The discovery of superconductivity in La3Ni2O7 has attracted significant research interest in the field of nickelate superconductors. Despite extensive studies on pristine La3Ni2O7…
Understanding spin textures in PT-broken systems through universal symmetry-constrained rules
Wei Tan, Jianfeng Wang, Yang Li +1
The current understanding of spin-polarization phenomena in crystals relies heavily on the development of specific k.p Hamiltonians. A more fundamental and symmetry-driven understa…
A composite ansatz for the calculation of dynamical structure factor
Yupei Zhang, Chongjie Mo, Ping Zhang +1
We propose an ansatz without adjustable parameters for the calculation of dynamical structure factor. The ansatz combines quasi-particle Green's function, especially the contributi…
Giant Bulk Electro-photovoltaic Effect in Hetero-nodal-line Systems
Xiao Jiang, Lei Kang, Jianfeng Wang +1
Realization of giant and continuously tunable second-order photocurrent is desired for many nonlinear optical (NLO) and optoelectronic applications, which remains to be a great cha…
Electronic Correlation-driven Exotic Quantum Phase Transitions in Infinite-layer Manganese Oxide
Heng Jin, Bing Huang
Despite the intensive interest in copper- and nickel-based superconductivity in infinite-layer structures, the physical properties of many other infinite-layer transition-metal oxi…
