Kavli Affiliate: Alireza Marandi | First 5 Authors: Luis Ledezma, Arkadev Roy, Luis Costa, Ryoto Sekine, Robert Gray | Summary: Widely-tunable coherent sources are desirable in nanophotonics for a multitude of applications ranging from communications to sensing. The mid-infrared spectral region (wavelengths beyond 2 $mu$m) is particularly important for applications relying on molecular spectroscopy. Among […]
Kavli Affiliate: Xiang Zhang | First 5 Authors: Xiang Zhang, Lijun Yin, , , | Summary: Multi-modal learning has been intensified in recent years, especially for applications in facial analysis and action unit detection whilst there still exist two main challenges in terms of 1) relevant feature learning for representation and 2) efficient fusion for […]
Kavli Affiliate: Hu Zhan | First 5 Authors: Hengjie Lin, Yan Gong, Xuelei Chen, Kwan Chuen Chan, Zuhui Fan | Summary: China Space Station Telescope (CSST) is a forthcoming powerful Stage IV space-based optical survey equipment. It is expected to explore a number of important cosmological problems in extremely high precision. In this work, we […]

Kavli Affiliate: Giorgio Gratta | First 5 Authors: Charles P. Blakemore, Denzal Martin, Alexander Fieguth, Nadav Priel, Gautam Venugopalan | Summary: Librational motion, whereby a rigid body undergoes angular oscillation around a preferred direction, can be observed in optically trapped, silica microspheres. We demonstrate the cooling of one librational degree of freedom for $sim 5~mu$m […]

Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: William J. Fischer, Lynne A. Hillenbrand, Gregory J. Herczeg, Doug Johnstone, Ágnes Kóspál | Summary: Variable accretion in young stellar objects reveals itself photometrically and spectroscopically over a continuum of timescales and amplitudes. Most dramatic are the large outbursts (e.g., FU Ori, V1647 Ori, and EX […]

Kavli Affiliate: Zhuo Li | First 5 Authors: Jiayu Li, Zhuo Li, Xiu Liu, Stanislav Maslovski, Sheng Shen | Summary: Metasurfaces, together with graphene plasmonics, have become prominent for the emissivity control in thermal engineering, both passively through changing the geometric parameters and packing density of the metasurfaces, and actively through graphene gating or doping. […]
Kavli Affiliate: Jing Wang | First 5 Authors: Jing Wang, Liying Kang, Yusai Xue, , | Summary: For a simple graph $F$, let $mathrm{Ex}(n, F)$ and $mathrm{Ex_{sp}}(n,F)$ denote the set of graphs with the maximum number of edges and the set of graphs with the maximum spectral radius in an $n$-vertex graph without any copy […]
