Observing the Minkowskian dynamics of the pion on the null-plane
W. de Paula, E. Ydrefors, J. H. Alvarenga Nogueira +2
A dynamical model is applied to the study of the pion valence light-front wave function, obtained from the actual solution of the Bethe-Salpeter equation in Minkowski space, resort…
Cold atom-dimer reaction rates with He, Li and Na
Mahdi A. Shalchi, Marcelo T. Yamashita, Tobias Frederico +1
Atom-dimer exchange and dissociation reaction rates are predicted for different combinations of two He atoms and one of the alkaline species among Li, Li and $^{23}…
Wavepacket Modelling of Broadband Shock-Associated Noise in Supersonic Jets
Marcus H. Wong, Peter Jordan, Igor A. Maia +4
We present a two-point model to investigate the underlying source mechanisms for broadband shock-associated noise (BBSAN) in shock-containing supersonic jets. In the model presente…
Emergence of N-body tunable interactions in universal few-atom system
Marcelo T. Yamashita, Tobias Frederico, Lauro Tomio
A three-atom molecule AAB, formed by two identical bosons A and a distinct one B, is studied by considering coupled channels close to a Feshbach resonance. It is assumed that the s…
Causality in the shock wave/turbulent boundary layer interaction
Kenzo Sasaki, Diogo C. Barros, André V. G. Cavalieri +1
The mechanisms governing the low-frequency unsteadiness in the shock wave/turbulent boundary layer interaction at Mach 2 are considered. The investigation is conducted based on the…
Tunneling Enhancement of the Gas-Phase CH + CO2 Reaction at Low Temperature
Dianailys Nunez-Reyes, Kevin M. Hickson, Jean-Christophe Loison +4
The rates of numerous activated reactions between neutral species increase at low temperatures through quantum mechanical tunneling of light hydrogen atoms. Although tunneling proc…
