Non-linear transport in multifold semimetals
Andrea Kouta Dagnino, Xiaoxiong Liu, Titus Neupert
Transport measurements are a powerful way to probe the electronic structure of quantum materials, but the information they contain is often convoluted. Yet, in particular for simpl…
Anatomy of anomalous Hall effect due to magnetic fluctuations
Ola Kenji Forslund, Xiaoxiong Liu, Soohyeon Shin +16
The anomalous Hall {\color{black} e}ffect (AHE) has emerged as a key indicator of time-reversal symmetry breaking (TRSB) and topological features in electronic band structures. Abs…
Discovery of a Topological Charge Density Wave
Maksim Litskevich, Md Shafayat Hossain, Songbo Zhang +21
Charge density waves (CDWs) appear in numerous condensed matter platforms, ranging from high-Tc superconductors to quantum Hall systems. Despite such ubiquity, there has been a lac…
Discovery of a topological exciton insulator with tunable momentum order
Md Shafayat Hossain, Tyler A. Cochran, Yu-Xiao Jiang +27
Correlated topological materials often maintain a delicate balance among physical symmetries: many topological orders are symmetry protected, while most correlated phenomena arise…
Covariant derivatives of Berry-type quantities: Application to nonlinear transport
Xiaoxiong Liu, Stepan S. Tsirkin, Ivo Souza
The derivatives of the Berry curvature and intrinsic orbital magnetic moment m in momentum space are relevant to various problems, including the nonlinear anomalous Hall effect…
Electrical magnetochiral anisotropy in trigonal tellurium from first principles
Xiaoxiong Liu, Ivo Souza, Stepan S. Tsirkin
Structural chirality gives rise to characteristic responses that change sign with the handedness of the crystal structure. One example is electrical magnetochiral anisotropy (eMChA…
Emergent Edge Modes in Shifted Quasi-One-Dimensional Charge Density Waves
Song-Bo Zhang, Xiaoxiong Liu, Md Shafayat Hossain +3
We propose and study a two-dimensional (2D) phase of shifted charge density waves (CDW), which is constructed from an array of weakly coupled 1D CDW wires whose phases shift from o…
Origin of spin reorientation and intrinsic anomalous Hall effect in the kagome ferrimagnet TbMn6Sn6
D. Connor Jones, Suvadip Das, Hari Bhandari +6
TbMnSn has attracted a lot of recent interest for a variety of reasons, most importantly, because of the hypothesis that it may support quantum-limit Chern topological magn…
Triple nodal points characterized by their nodal-line structure in all magnetic space groups
Patrick M. Lenggenhager, Xiaoxiong Liu, Titus Neupert +1
We analyze triply degenerate nodal points [or triple points (TPs) for short] in energy bands of crystalline solids. Specifically, we focus on spinless band structures, i.e., when s…
Signatures of Weyl fermion annihilation in a correlated kagome magnet
Ilya Belopolski, Tyler A. Cochran, Xiaoxiong Liu +22
The manipulation of topological states in quantum matter is an essential pursuit of fundamental physics and next-generation quantum technology. Here we report the magnetic manipula…
Universal higher-order bulk-boundary correspondence of triple nodal points
Patrick M. Lenggenhager, Xiaoxiong Liu, Titus Neupert +1
Triple nodal points are degeneracies of energy bands in momentum space at which three Hamiltonian eigenstates coalesce at a single eigenenergy. For spinless particles, the stabilit…
Discovery of unconventional chiral charge order in kagome superconductor KV3Sb5
Yu-Xiao Jiang, Jia-Xin Yin, M. Michael Denner +23
Intertwining quantum order and nontrivial topology is at the frontier of condensed matter physics. A charge density wave (CDW) like order with orbital currents has been proposed as…
From triple-point materials to multiband nodal links
Patrick M. Lenggenhager, Xiaoxiong Liu, Stepan S. Tsirkin +2
We study a class of topological materials which in their momentum-space band structure exhibit three-fold degeneracies known as triple points. Focusing specifically on $\mathcal{P}…

Ilya Belopolski, Tyler A. Cochran, Stepan S. Tsirkin +13
The search for novel topological phases of matter in quantum magnets has emerged as a frontier of condensed matter physics. Here we use state-of-the-art angle-resolved photoemissio…
