# Efimov effect in D spatial dimensions in AAB systems

@article{Rosa2017EfimovEI, title={Efimov effect in D spatial dimensions in AAB systems}, author={D. S. Rosa and Tobias Frederico and G. Krein and M. T. Yamashita}, journal={Physical Review A}, year={2017}, volume={97}, pages={5} }

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 can be continuosly modified by compressing it in one or two directions. In the present paper we determine, for a general $AAB$ system formed by two identical bosons $A$ and a third particle $B$, the dimensionsality $D$ for which the Efimov effect can exist for different values of the mass ratio $\mathpzc{A}=m_B…
