Abstract
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 continuously modified by compressing it in one or two directions. In the present Rapid Communication we determine the dimensionality for which the Efimov effect can exist for different values of the mass ratio for a general system formed by two identical bosons and a third particle in the two-body unitary limit. In addition, we provide a prediction for the Efimov discrete scaling factor as a function of a wide range of values of and , which can be tested in experiments that can be realized with currently available technology.
