摘要:The deconfined quantum critical point (DQCP) represents a paradigm shift in quantum matter studies, presenting a beyond Landau scenario for order-order transitions. Its experimental realization, however, has remained elusive. Using high-pressure 11B nuclear magnetic resonance measurements on the quantum magnet SrCu2(BO3)2, we here demonstrate a magnetic field- induced plaquette singlet to antiferromagnetic transition above 1.8 gigapascals at a notably low temperature, Tc similar or equal to 0....

摘要:Understanding the causes and potential mitigations of light pollution requires measuring and monitoring artificial light at night (ALAN). We review how ALAN is measured, both from the ground and through remote sensing by satellites in Earth orbit. A variety of techniques are described, including single-channel photometers, all-sky cameras, and drones. Spectroscopic differences between light sources can be used to determine which are most responsible for light pollution, but they complicate the...
