Floquet Engineering in Hybrid Magnetic Quantum Systems

A team of researchers has demonstrated the ability to coherently manipulate quantum states in a hybrid system combining a diamond nitrogen-vacancy (NV) center with a magnetic topological insulator. This advance, utilizing Floquet engineering, allows for the control of interactions between the NV center spins and the magnetic excitations of the topological material, known as magnons.…

New Adherents to the Artemis Accords for Space Exploration

Last week, the United States participated in an Artemis Accords workshop in Lima, Peru, at a time of growing international commitment to lunar and Martian exploration. This event followed the accession of six new nations—Latvia, Jordan, Morocco, Malta, Ireland, and Paraguay—to the coalition of Artemis Accords signatories, raising the total number of participating countries to 33. These accords, led by NASA, establish a framework of principles for safe, peaceful, and sustainable space exploration, building on the 1967 Outer Space Treaty.

The Artemis Accords seek to foster international cooperation in the exploration of the Moon, Mars, and other celestial bodies, promoting transparency, system interoperability, emergency assistance, registration of space objects, and protection of space heritage. Furthermore, they address the sustainable utilization of space resources and the prevention of harmful interference. The growing global participation underscores the importance of establishing clear norms as more nations and private entities become involved in space activities, especially in the context of NASA's Artemis lunar program, which aims to establish a sustained human presence on the Moon.
