Sažetak
I will present our study of weakly bound dimers and trimers with a radius extending well into the classically forbidden region, performed with the goal to test the predicted universality of quantum halo states. The focus were molecules consisting of T↓, D↓, 3He, 4He and alkali atoms, where interaction between particles is much better known than in the case of nuclei, which are traditional examples of quantum halos. The exploration of realistic systems was supplemented by model calculations in order to analyze how low-energy properties depend on the interaction potential. The use of variational and diffusion Monte Carlo methods enabled very precise calculation of both size and binding energy of the trimers. For the first time, we were able to establish both the more convenient scaling variables and the universal line which dimer and trimer halo states follow. Finally, we were able to observe, and determine when, universal line of tango trimers departs from the Borromean one.
