Three-body bound states of two bosons and one impurity in one dimension
Three-body bound states of two bosons and one impurity in one dimension
We investigate one-dimensional three-body systems composed of two identical bosons and one mass-imbalanced atom (impurity) with attractive two-body and three-body zero-range interactions. In the absence of three-body interaction, we give a complete phase diagram of the number of three-body bound states in the whole region of mass ratio and the …
