Crystalline Germanium Josephson Junctions

Frederik H. Knudsen, Axel Leblanc, Yiliu Li, Patrick J. Strohbeen et autres

Conventional superconducting quantum electronics rely on well-established Josephson junctions made of Al/AlO$_{x}$ where the weak link AlO$_{x}$ is amorphous and is believed to host two-level systems that limit coherence. Crystalline Josephson junctions exhibit atomically ordered interface quality but remain constrained by complex …

MLFFM-SegDiff: A Multi-Level Feature Fusion Diffusion Model for Skin Lesion Segmentation

Jingjun Gu, Chaojie Shen, Yifeng Cao, Wei Zhang et autres

Skin lesion segmentation is a key task in computer-aided dermatological diagnosis, where accuracy directly impacts downstream analysis and disease classification. However, dermoscopic images are challenging due to blurred boundaries, low contrast, large shape variations, and artifacts such as hair and shadows. Recently, …

Photoinduced Metal-to-Insulator Transitions in 2D Moiré Devices

Yiliu Li, Esteban Rojas‐Gatjens, Yinjie Guo, Birui Yang et autres

Photoexcitation has been utilized to control quantum matter and to uncover metastable phases far from equilibrium. Among demonstrations to date, the most common is the photoinduced transition from correlated insulators to metallic states; however, the reverse process without initial orders has not …

Macroscopic Transition Metal Dichalcogenide Monolayers from Gold-Tape Exfoliation Retain Intrinsic Properties

Nicholas Olsen, Sunggun Yoon, Madisen Holbrook, Morgan Thinel et autres

The "gold-tape" exfoliation technique can deterministically exfoliate macroscopic transition metal dichalcogenide (TMD) monolayers from bulk single crystals, overcoming limitations of the widely used "Scotch-tape" method, but concerns over the quality of the large-area monolayers remain. Here we introduce a critical step improving …

Observing the Birth of Rydberg Exciton Fermi Polarons on a Moire Fermi Sea

Eric A. Arsenault, Gillian E. Minarik, Jiaqi Cai, Minhao He et autres

The optical spectra of two-dimensional (2D) semiconductors are dominated by tightly bound excitons and trions. In the low doping limit, trions are often described as three-body quasiparticles consisting of two electrons and one hole or vice versa. However, trions are more rigorously …
