Altermagnetism produces pair emission and absorption from dark excitons and magnons in LaOMnSe
Birender Singh, Xian Xu, Sabrina R. Hatt +21
Altermagnets' (AMs) non-relativistic spin splitting enables novel states, spintronic and magneto-optical devices, though their optical signatures remain elusive. Here, we report ex…
Anomalous Non-Hermitian Topological Anderson Insulator
Mina Ren, Xi Shi, Haitao Jiang +3
Strong disorder drives conventional Hermitian systems into Anderson insulating states, suppressing all topological phases. Here, we unveil symmetry-protected, anomalous topological…
Orbital Altermagnetism in Two Dimensions
Mingxiang Pan, Feng Liu, Huaqing Huang
We introduce the concept of \emph{orbital altermagnetism}, a symmetry-protected magnetic order of pure orbital degrees of freedom. It is characterized with ordered anti-parallel or…
High Harmonic Spectroscopy from Lower-Order to Higher-Order Topological Insulators
Bryan Lorenzo, Carlos Batista, Milad Jangjan +7
Over the past decades, high-harmonic spectroscopy (HHS) has emerged as a powerful tool for all-optical probing of topological properties of solids. There are outstanding questions…
LaOMnSe: a correlated insulating layered d-wave altermagnet
Chao-Chun Wei, Xiaoyin Li, Sabrina Hatt +12
Altermagnets represent a new class of magnetic phases without net magnetization that are invariant under a combination of rotation and time reversal. Unlike conventional collinear…
Hierarchical Topological States in Thermal Diffusive Networks
Bao Chen, Kaiyun Pang, Ru Zheng +1
The integration of topological concepts into electronic energy band theory has been a transformative development in condensed matter physics. Since then, this paradigm has broadene…
Graph Theorem for Chiral Exact Flat Bands at Charge Neutrality
Gurjyot Sethi, Bowen Xia, Dongwook Kim +3
Chiral exact flat bands (FBs) at charge neutrality have attracted much recent interest, presenting an intriguing condensed-matter system to realize exact many-body phenomena, as sp…
