Residual orbital magnetization governs the anomalous Hall effect in altermagnets
Yufei Zhao, Yiyang Jiang, Kamal Das +2
In altermagnets that exhibit anomalous Hall effect, the small remanent magnetization exists but has been treated as too small to be relevant to the Hall response. In this work, we…
Linear Magnetoresistance as a Probe of the Neel Vector in Altermagnets with Vanishing Anomalous Hall Effect
Kamal Das, Binghai Yan
Despite time-reversal breaking in momentum space, several altermagnets remain electrically silent to the primary characterization tool anomalous Hall effect, due to crystalline sym…
QMBench: A Research Level Benchmark for Quantum Materials Research
Yanzhen Wang, Yiyang Jiang, Diana Golovanova +10
We introduce QMBench, a comprehensive benchmark designed to evaluate the capability of large language model agents in quantum materials research. This specialized benchmark assesse…
Direct observation of distinct bulk and edge nonequilibrium spin accumulation in ultrathin MoTe
Fangchu Chen, Kamal Das, Bowen Yang +11
Low-symmetry two-dimensional (2D) topological materials such as MoTe host efficient charge-to-spin conversion (CSC) mechanisms that can be harnessed for novel electronic and sp…
Surface-Dominated Quantum Metric-Induced Nonlinear Transport in the Layered Antiferromagnet CrSBr
Kamal Das, Yufei Zhao, Binghai Yan
The van der Waals (vdW) antiferromagnet CrSBr has recently garnered significant attention due to its air stability, high magnetic transition temperature, and semiconducting propert…
