Infinite Setlist: Analyzing Pioneer DJ’s Catalogue Streaming Partnerships with Beatport and SoundCloud

The purpose of this paper is to examine the partnerships Rekordbox has with SoundCloud and Beatport, determine if user agreements of each platform legally allow the partnerships to occur, what the implications are of using the music streaming service for live performances at venues, what the implications are of streaming music for live streamed performances via the internet, satellite radio, and terrestrial radio, and determine which types of copyright royalties need to be paid to who and by whom

Light-matter interactions with photonic quasiparticles

Interactions between light and matter play an instrumental role in many fields of science, giving rise to important applications in spectroscopy, sensing, quantum information processing, and lasers. In most of these applications, light is considered in terms of electromagnetic plane waves that propagate at the speed of light in vacuum. As a result, light-matter interactions can usually be treated as very weak, and captured at the lowest order in quantum electrodynamics (QED). However, recent progress in coupling photons to material quasiparticles (e.g., plasmons, phonons, and excitons) forces us to generalize the way we picture the photon at the core of every light-matter interaction. In this new picture, the photon, now of partly matter-character, can have greatly different polarization and dispersion, and be confined to the scale of a few nanometers. Such photonic quasiparticles enable a wealth of light-matter interaction phenomena that could not have been observed before, both in interactions with bound electrons and with free electrons. This Review focuses on exciting theoretical and experimental developments in realizing new light-matter interactions with photonic quasiparticles. As just a few examples, we discuss how photonic quasiparticles enable room-temperature strong coupling, ultrafast "forbidden transitions" in atoms, and new applications of the Cherenkov effect, as well as breakthroughs in ultrafast electron microscopy and new concepts for compact X-ray sources
