Three-body recombination in heteronuclear mixtures at finite temperature

DS Petrov, F Werner - Physical Review A, 2015 - APS
Within the universal zero-range theory, we compute the three-body recombination rate to
deep molecular states for two identical bosons resonantly interacting with each other and …

Efimov effect in spatial dimensions in systems

DS Rosa, T Frederico, G Krein, MT Yamashita - Physical Review A, 2018 - APS
The existence of the Efimov effect is drastically affected by the dimensionality of the space in
which the system is embedded. The effective spatial dimension containing an atomic cloud …

Squeezing the Efimov effect
