Electric Edelstein Effect in Two Dimensions
Xiaoran Lv, Tianqi Zhang, Chaoxi Cui +6
We propose the electric Edelstein effect (EEE) in two-dimensional (2D) systems, where crossed out-of-plane and in-plane electric fields generate a spin polarization. The gate field…
The Price of Precision: A Calibrated Cost Model for Mixed-Precision LLM Serving
Mukund Athmaram, Manoj Rao, Liang Ma
Choosing a mixed-precision configuration for large language model (LLM) serving trades speed against accuracy. Allocators that use average bit-width or a memory budget as a speed p…
Magnetic-Field Selection of Magnetic Order in Altermagnets and Noncollinear Antiferromagnets
Qiu-Shi Huang, Chaoxi Cui, Yilin Han +3
Conventional field selection of magnetic order relies on the Zeeman coupling, which, however, vanishes in magnets without net magnetization, a rapidly growing class including alter…
