Ex Situ Fabrication of Superconducting Nanostructures for Low-Temperature STM
Nanofabrication enables flexible experimental design but is often incompatible with scanning tunneling microscopy and spectroscopy (STM/STS) due to the latter's stringent surface quality requirements. Here, we present a fabrication strategy that combines ex situ nanolithography with in situ ultrahigh-vacuum (UHV) cleaving to produce atomically clean, nanopatterned superconductor/topological insulator (TI) heterostructures suitable for high-resolution STM/STS. In our initial Design I, nanoribbon…

CTA: Cross-Task Alignment for Better Test Time Training
Deep learning models have demonstrated exceptional performance across a wide range of computer vision tasks. However, their performance often degrades significantly when faced with distribution shifts, such as domain or dataset changes. Test-Time Training (TTT) has emerged as an effective method to enhance model robustness by incorporating an auxiliary unsupervised task during training and leveraging it for model updates at test time. In this work, we introduce CTA (Cross-Task Alignment), a nov…
