3、 March 25, 2014 (Tuesday) Time: 1:30 - 2:30 p.m. Place: Room 311, Science Centre North Block, CUHK ALL INTERESTED ARE WELCOME * Abstract Majorana Fermion (MF), a particle which is its own antiparticle, has been predicted more than 80 years in elementary particle physics, however, its physical realiz
4、ation using quasi-particles in condensed matter physics and ultracold atoms is always of great challenging. The breakthrough is made based on the simple idea that spin-orbit coupling (SOC) and s-wave pairing, which can lead to induced p-wave pairing in some parameter regime. This is nothing, but the
5、 basic requirement of anti- symmetry for the pair function for fermionic condensation. This idea stimulates the searching of MFs with semiconductors in proximity to s-wave superconductor as well as spin-orbit coupled degenerate Fermi gas. In this Seminar, I want to tell an interesting story of Fermi
6、 surface and its topology from the viewpoint of symmetry. I will show how topology and pairing symmetry, from BCS pairing to finite momentum pairing (FFLO phase), can be realized by carefully controlling the Zeeman field and its polarization. I will also briefly discuss its physical realization with
7、 solid materials, in which we show that all the semiconductors nanowires even with small Lande g factor, in principle, can be used to realize MFs.
