    “…We demonstrate the creation of large, out-of-equilibrium magnon densities in a thin-film magnetic insulator via microwave excitation of coherent spin waves and subsequent multimagnon scattering. We image both the coherent spin waves and the resulting incoherent magnon gas using scanning-probe magnetometry based on electron spins in diamond. …”

    “…Numerous studies have reported that CO(2) emissions have decreased because of global lockdown during the first wave of the COVID-19 pandemic. However, previous estimates of the global CO(2) concentration before and after the outbreak of the COVID-19 pandemic are limited because they are based on energy consumption statistics or local specific in-situ observations. …”
