Hydrostatic Pressure-Induced Evolution of the Superconducting Transition Temperature of Bi-2212: Insights from First-Principles Calculations
Shuhong Tang, Hanyu Wang, Di Peng +3
High-pressure experiments on BiSrCaCuO (Bi-2212) have reported apparently conflicting evolutions of the superconducting transition temperature , ranging fr…
Pressure and doping control of magnetic order and metallization in Ruddlesden-Popper La2NiO4
Han-Yu Wang, Shu-Hong Tang, Xiao-Teng Huang +7
The discovery of superconductivity in multilayer nickelates under pressure has intensified interest in understanding the magnetic and electronic properties of Ruddlesden-Popper nic…
Chirality-selective topological magnon phase transition induced by interplay of anisotropic exchange interactions in honeycomb ferromagnet
Jin-Yu Ni, Xia-Ming Zheng, Peng-Tao Wei +2
A variety of distinct anisotropic exchange interactions commonly exist in one magnetic material due to complex crystal, magnetic and orbital symmetries. Here we investigate the eff…
Multiple topological phases of magnons induced by Dzyaloshinskii-Moriya and pseudodipolar anisotropic exchange interactions in Kagome ferromagnets
Jin-Yu Ni, Xia-Ming Zheng, Peng-Tao Wei +2
Kagome magnets naturally hosting Dirac points and flat bands exhibit novel topological phases, enabling rich interplays between interactions and topologies. The discovery of two-di…
Universal quasi-degenerate orbital origin of two-dome phases in iron pnictide superconductors
Da-Yong Liu, Zhe Sun, Feng Lu +2
A series of experiments revealed that novel bipartite magnetic and superconducting (SC) phases widely exist in the phase diagrams of iron pnictides and chalcogenides. Nevertheless,…
Evolution of correlated electronic states of La2NiO4 under hydrostatic pressure
Shu-Hong Tang, Han-Yu Wang, Da-Yong Liu +4
We elucidate the electronic structure and quantum many-body instabilities of the monolayer nickelate La2NiO4 under hydrostatic pressure using a combination of density functional th…
