Rotation of polarization of light propagating through a gas of molecular super-rotors
Ilia Tutunnikov, Uri Steinitz, Erez Gershnabel +4
We present a detailed theoretical and experimental study of the rotation of the plane of polarization of light traveling through a gas of fast-spinning molecules. This effect is si…
Evolution of hybrid quantum-classical wavefunctions
François Gay-Balmaz, Cesare Tronci
A gauge-invariant wave equation for the dynamics of hybrid quantum-classical systems is formulated by combining the variational setting of Lagrangian paths in continuum theories wi…
No detection of SO2, H2S, or OCS in the atmosphere of Mars from the first two Martian years of observations from TGO/ACS
Ashwin S. Braude, F. Montmessin, K. S. Olsen +13
The detection of sulphur species in the Martian atmosphere would be a strong indicator of volcanic outgassing from the surface of Mars. We wish to establish the presence of SO2, H2…
Importance of the advection scheme for the simulation of water isotopes over Antarctica by atmospheric general circulation models: A case study for present-day and Last Glacial Maximum with LMDZ-iso
Alexandre Cauquoin, Camille Risi, Étienne Vignon
Atmospheric general circulation models (AGCMs) are known to have a warm and isotopically enriched bias over Antarctica. We test here the hypothesis that these biases are partly con…
The global distribution of natural tritium in precipitation simulated with an Atmospheric General Circulation Model and comparison with observations
Alexandre Cauquoin, Philippe Jean-Baptiste, Camille Risi +3
The description of the hydrological cycle in Atmospheric General Circulation Models (GCMs) can be validated using water isotopes as tracers. Many GCMs now simulate the movement of…
Global fossil carbon emissions rebound near pre-COVID-19 levels
RB Jackson, P Friedlingstein, C Le Quere +8
Global fossil CO2 emissions in 2020 decreased 5.4%, from 36.7 Gt CO2 in 2019 to 34.8 Gt CO2 in 2020, an unprecedented decline of ~1.9 Gt CO2. We project that global fossil CO2 emis…
