Selective Manipulation and Tunneling Spectroscopy of Broken-Symmetry Quantum Hall States in a Hybrid-edge Quantum Point Contact

Kavli Affiliate: Ke Wang | First 5 Authors: , , , , | Summary: We present a device architecture of hybrid-edge and dual-gated quantum point contact. We demonstrate improved electrostatic control over the separation, position, and coupling of each broken-symmetry compressible strip in graphene. Via low-temperature magneto-transport measurement, we demonstrate selective manipulation over the evolution, […]

How Does Diffusion Influence Pretrained Language Models on Out-of-Distribution Data?

Kavli Affiliate: Jing Wang | First 5 Authors: Huazheng Wang, Daixuan Cheng, Haifeng Sun, Jingyu Wang, Qi Qi | Summary: Transformer-based pretrained language models (PLMs) have achieved great success in modern NLP. An important advantage of PLMs is good out-of-distribution (OOD) robustness. Recently, diffusion models have attracted a lot of work to apply diffusion to […]
