Abstract

We present our proposals for generating a total-hyperfine-spin-zero state for two f=1 or two f=2 particles, starting from initial unentangled states. We show that our goal can be achieved by exploiting spin-changing dynamics and quadratic Zeeman shifts with realistic choices of external magnetic fields and evolution time intervals.
