Unraveling the mechanisms of triplet state formation in a heavy-atom free photosensitizer

Kavli Affiliate: David T. Limmer | First 5 Authors: Thomas P. Fay, David T. Limmer, , , | Summary: Triplet excited state generation plays a pivotal role in photosensitizers, however the reliance on transition metals and heavy atoms can limit the utility of these systems. In this study, we demonstrate that an interplay of competing […]

Floquet topological phases with large winding number

Kavli Affiliate: Xiang Zhang | First 5 Authors: Kaiye Shi, Xiang Zhang, Wei Zhang, , | Summary: Recently, anomalous Floquet topological phases without static counterparts have been observed in different systems, where periodically driven models are realized to support a winding number of 1 and a pair of edge modes in each quasienergy gap. Here, […]

Optical-parametric-amplification-enhanced background-free spectroscopy

Kavli Affiliate: Alireza Marandi | First 5 Authors: Mingchen Liu, Robert M. Gray, Arkadev Roy, Luis Ledezma, Alireza Marandi | Summary: Traditional absorption spectroscopy has fundamental difficulty in resolving small absorbance from strong background due to the instability of laser sources. Existing background-free methods in broadband vibrational spectroscopy help to alleviate this problem but face […]

QGFace: Quality-Guided Joint Training For Mixed-Quality Face Recognition

Kavli Affiliate: Feng Wang | First 5 Authors: Youzhe Song, Feng Wang, , , | Summary: The quality of a face crop in an image is decided by many factors such as camera resolution, distance, and illumination condition. This makes the discrimination of face images with different qualities a challenging problem in realistic applications. However, […]
