Finite-temperature adiabatic-connection reduced density-matrix functional theory: a unified framework for i-DMFT and TAO-DFT
Jingang Han, Huanjing Gong, Kai Luo +2
Accurately describing chemical bond breaking requires capturing strong/static electron correlation, a major challenge for single-reference self-consistent-field methods such as Har…
Relative hybridization textures as local coordinates for band geometry and topology
Caiyuan Ye, Zhong Fang, Hongming Weng +1
Global diagnostics such as Berry curvature and quantum metrics characterize the geometry and topology of an occupied Bloch subspace, leaving the microscopic sectors that carry this…
A Catalogue of Topological Moiré Bands in Twisted Semiconductors
Jiaheng Li, Yan Zhang, Jiaxuan Liu +5
Twisted two-dimensional semiconductors provide a route to flat and topological moiré minibands, but systematic principles for organizing their material dependence have remained unc…
Entropy-Driven Structural Phase Transition in NbCl via Density Functional Theory and an Effective Model
Chenjie Zhu, Shuai Zhang, Zhong Fang +3
As a prototypical flat-band cluster Mott insulator on an effective triangular lattice, NbCl is a potential candidate for hosting a quantum spin liquid (QSL) state. Neverthe…
A Geometric Design Principle for Topological Phases in Twisted Triangular-Lattice Bilayers
Jiaheng Li, Jiaxuan Liu, Yan Zhang +3
Twisted van der Waals bilayers provide a versatile platform for moiré electronic states, yet a transferable symmetry-based principle for time-reversal-invariant moir…
Suppression of p-Wave Altermagnetism by Localized 4f Electrons in CeNiAsO
Jiuxiang Zhang, Yueyang Sun, Honglin Zhou +32
Altermagnetism, characterized by momentum-dependent spin splitting and zero net magnetization, has so far been explored mainly in weakly or moderately correlated d-electron systems…
Disentangling Anomalous Hall Effect Mechanisms and Extra Symmetry Protection in Altermagnetic Systems
Yuansheng Bu, Ziyin Song, Zhong Fang +2
We investigate the evolution of Anomalous Hall Conductivity (AHC) in a coplanar and collinear antiferromagnetic system with varying spin canting angles. A tight-binding model based…
Symmetry-Indicated Time-Reversal-Doubled Axion Insulators
Yue Xie, Haohao Sheng, Quansheng Wu +4
The axion insulator exhibits a topological magnetoelectric effect characterized by an axion angle , while the time-reversal-doubled axion insulator (T-DAXI) can be viewed as t…
Majorana Zero Modes and Topological Nature in Bi2Ta3S6-family Superconductors
Yue Xie, Zhilong Yang, Ruihan Zhang +7
In this work, we report that Bi2Ta3S6-family superconductors exhibit nontrivial band topology. They possess a natural quantum-well structure consisting of alternating stacks of TaS…
