Perovskite-quantum-dot plasmonic nanolasers with ultralow thresholds Yu-Jung Lu To date, the size of conventional lasers, which is usually larger than half of their wavelength due to the diffraction limit, hinders their applications in on-chip integration and ultracompact optoelectronic devices. The miniaturization of optoelectronic components has gradually become an important research topic, especially for nanolasers. How can the size of lasers be reduced? How can the power consumption of lase

Exploring antiquark asymmetry in protons Wen-Chen Chang and Shin'ya Sawada Protons and neutrons, the components of every nucleus, are the dominating mass carriers of our visible universe. Our understanding of protons and neutrons (i.e., nucleons) has been evolving from a simple 3-quark structure to the 1d longitudinal momentum fraction (x) distributions of quarks and gluons and the multi-dimensional distributions with additional dependency on transverse size or transverse momentum. Inside the n
