Abstract:

Majorana fermions (MFs), quantum particles that are their own antiparticles, are not only of fundamental importance in elementary particle physics and dark matter, but also building blocks for fault tolerant quantum computation. Recently MFs have been intensively studied in solid state and cold atomic systems. These studies are generally based on superconducting pairing with zero total momentum. On the other hand, finite total momentum Cooper pairings, known as

Fulde Ferrell (FF) Larkin–Ovchinnikov (LO) states, were widely studied in many branches of physics. Our recent work shows that MFs can also exist in certain types of gapped FF states, yielding a new quantum matter: topological FF superfluids/superconductors. In this talk, I will discuss such topological FF superfluids and the associated MFs in spin–orbit-coupled degenerate Fermi gases.
