On Worst-Case Guarantees for Graph-Based Nearest-Neighbor Search
Majid Daliri, Mohammadreza Daneshvaramoli, Purna Dutta +4
Graph-based nearest neighbor search algorithms like HNSW, DiskANN, NSG, and others have surged in popularity in recent years due to their excellent empirical performance in compari…
Probing (sub)nanoscale ferrons in an electron microscope
Mahir Manna, Fei Yang, Shayantan Chaudhuri +13
Ferrons are collective excitations of polarization fluctuations that can enable terahertz communications and quantum transduction due to long propagation lengths. Although ferrons…
Harnessing the polar vortex motion in oxide heterostructures
Pushpendra Gupta, Mohit Tanwani, Qi Xu +7
Polar topology, an analogue of the magnetic topology, serves as a large playground for exotic physical phenomena with a wide range of multifunctional applications. Polar vortices a…
PTST: A polar topological structure toolkit and database
Guanshihan Du, Yuanyuan Yao, Linming Zhou +11
Ferroelectric oxide superlattices with complex topological structures such as vortices, skyrmions, and flux closure domains have garnered significant attention due to their fascina…
