Two-Dimensional Photogalvanic Spin-Battery

Yiqun Xie, Mingyan Chen, Zewen Wu +4

Pure spin-current is of central importance in spintronics. Here we propose a two-dimensional (2D) spin-battery system that delivers pure spin-current without an accompanying charge…

Direct tunneling through high- amorphous HfO: effects of chemical modification

Yin Wang, Zhizhou Yu, Ferdows Zahid +4

We report first principles modeling of quantum tunneling through amorphous HfO dielectric layer of metal-oxide-semiconductor (MOS) nanostructures in the form of n-Si/HfO/Al…

APEX4: Efficient Pure W4A4 LLM Inference via Intra-SM Compute Rebalancing

Hong Guo, Nianhui Guo, Weixing Wang +3

W4A4 quantization promises full utilization of INT4 Tensor Cores, yet group dequantization overhead on CUDA Cores has driven existing systems to mixed-precision fallbacks. We prese…

Continuous-variable measurement-device-independent quantum key distribution with virtual photon subtraction

Yijia Zhao, Yi-Chen Zhang, Bingjie Xu +2

The method of improving the performance of continuous-variable quantum key distribution protocols by post-selection has been recently proposed and verified. In continuous-variable…

Manipulation of the quantum state by Majorana transition in spinor Bose-Einstein condensates

Lin Xia, Xu Xu, Fan Yang +6

Manipulation of the quantum state by the Majorana transition in spinor BEC system has been realized by altering the rotation frequency of the magnetic field's direction. This kind…

A holographic model of d-wave superconductor vortices with Lifshitz scaling

Hong Guo, Fu-Wen Shu, Jing-He Chen +2

We study analytically the -wave holographic superconductors with Lifshitz scaling in the presence of external magnetic field. The vortex lattice solutions of the model have also…
