Spin-orbit coupled cold atom systems, governed by Hamiltonians that contain quadratic kinetic energy terms typical for a particle's motion in the usual Schroedinger equation and linear kinetic energy terms typical for a particle's motion in the usual Dirac equation, have attracted a great deal of attention recently since they provide an alternative route for realizing fractional quantum Hall physics, topological insulators, and spintronics physics. This talk will discuss selected few-body aspects of spin-orbit coupled cold atom systems. Considering the experimentally most frequently realized 1D spin-orbit coupling, two topics will be discussed. 1) It will be shown that weak spin-orbit coupling terms can notably modify the two-body scattering properties. 2) It will be discussed what happens to Efimov's famous radial scaling law if single-particle spin-orbit coupling terms are added to the three-boson Hamiltonian with two-body short-range interactions.
