Kavli Affiliate: Simon Groblacher | First 5 Authors: Amirparsa Zivari, Niccolò Fiaschi, Lorenzo Scarpelli, Menno Jansen, Roel Burgwal | Summary: Integrated photonics has enabled countless technologies in telecommunications, spectroscopy, metrology, quantum optics, and quantum information processing. Using highly confined guided optical modes is the key that has made integrated circuits possible and has lead to […]
Kavli Affiliate: David Charbonneau | First 5 Authors: Allyson Bieryla, George Zhou, Juliana García-Mejía, Tyler R. Farnington, David W. Latham | Summary: We report the discovery of TOI-4641b, a warm Jupiter transiting a rapidly rotating F-type star with a stellar effective temperature of 6560 K. The planet has a radius of 0.73 $R_{Jup}$, a mass […]
Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Antonios M. Alvertis, Jonah B. Haber, Zhenglu Li, Christopher J. N. Coveney, Steven G. Louie | Summary: The properties of excitons, or correlated electron-hole pairs, are of paramount importance to optoelectronic applications of materials. A central component of exciton physics is the electron-hole interaction, which is […]
Kavli Affiliate: Debanjan Chowdhury | First 5 Authors: J. F. Mendez-Valderrama, Dan Mao, Debanjan Chowdhury, , | Summary: Few layers of graphene at small twist-angles have emerged as a fascinating platform for studying the problem of strong interactions in regimes with a nearly quenched single-particle kinetic energy and non-trivial band topology. Starting from the strong-coupling […]
Kavli Affiliate: Feng Wang | First 5 Authors: Ruishi Qi, Qize Li, Zuocheng Zhang, Sudi Chen, Jingxu Xie | Summary: The combination of repulsive and attractive Coulomb interactions in a quantum electron(e)-hole(h) fluid can give rise to novel correlated phases of multiparticle charge complexes such as excitons, trions and biexcitons. Here we report the first […]
Kavli Affiliate: Rana X. Adhikari | First 5 Authors: Mario Krenn, Yehonathan Drori, Rana X Adhikari, , | Summary: Gravitational waves, detected a century after they were first theorized, are spacetime distortions caused by some of the most cataclysmic events in the universe, including black hole mergers and supernovae. The successful detection of these waves […]
Kavli Affiliate: Xiang Zhang | First 5 Authors: Ruihan Xu, Ming Sun, Xiang Zhang, , | Summary: For the reduced two-dimensional Belousov-Zhabotinsky slow-fast differential system, the known results are the existence of one limit cycle and its stability for particular values of the parameters. Here, we characterize all dynamics of this system except one degenerate […]
Kavli Affiliate: Oskar Painter | First 5 Authors: Utku Hatipoglu, Sameer Sonar, David P. Lake, Srujan Meesala, Oskar Painter | Summary: Optomechanical crystals are a promising device platform for quantum transduction and sensing. Precise targeting of the optical and acoustic resonance frequencies of these devices is crucial for future advances on these fronts. However, fabrication […]
Kavli Affiliate: Feng Wang | First 5 Authors: Feng Wang, Jieru Mei, Alan Yuille, , | Summary: Recent advances in contrastive language-image pretraining (CLIP) have demonstrated strong capabilities in zero-shot classification by aligning visual representations with target text embeddings in an image level. However, in dense prediction tasks, CLIP often struggles to localize visual features […]
