Researchers create better algorithm for simulating particles in Fermi Sea

A North Carolina State University physicist and his German colleagues have created a new, more precise algorithm for simulating particle interactions when a single impurity is introduced into a Fermi sea. The algorithm shows that when these particles interact, the transition from quasiparticle to bound molecule in a polarized two-dimensional system is smooth. The new method may have implications for understanding the behavior of impurities in a variety of systems.
