Screening phonon-mediated superconductors from static orbital Hamiltonians
Jian-Feng Zhang, Ze-Feng Gao, Xiao-Qi Han +6
The first-principles search for superconductors is severely limited by the high cost of electron-phonon coupling (EPC) calculations. Here we develop a low-cost, physically transpar…
Bridging Crystal Structure and Material Properties via Bond-Centric Descriptors
Jian-Feng Zhang, Ze-Feng Gao, Xiao-Qi Han +7
Although chemical bonding is the fundamental mechanistic bridge connecting atomic structure to macroscopic material properties, current data-driven materials science largely treats…
Extreme Strain Controlled Correlated Metal-Insulator Transition in the Altermagnet CrSb
Cong Li, Mengli Hu, Jianfeng Zhang +14
Correlated flat bands and altermagnetism are two important directions in quantum materials, centred respectively on interaction-dominated phases and symmetry-enforced spin-textured…
Hidden Moiré Topology of Low-Symmetry Weyl Surfaces
Cong Li, Zhilong Yang, Hongxiong Liu +11
Topological materials are defined by the correspondence between bulk topology and boundary states, yet this correspondence becomes enigmatic on low-symmetry surfaces where bulk and…
Non-Hermitian Boundary in a Surface Selective Reconstructed Magnetic Weyl Semimetal
Cong Li, Yang Wang, Jianfeng Zhang +11
Non-Hermitian physics, studying systems described by non-Hermitian Hamiltonians, reveals unique phenomena not present in Hermitian systems. Unlike Hermitian systems, non-Hermitian…
Resolving the Electronic Ground State of La3Ni2O7-δ Films
Xiaolin Ren, Ronny Sutarto, Xianxin Wu +7
The recent discovery of a superconductivity signature in La3Ni2O7-δ under a pressure of 14 GPa, with a superconducting transition temperature of around 80 K, has attracted conside…
