Superconducting Bismuth Edge

Superconducting Bismuth Edge

Bismuth is a heavy element with a high atomic mass (208.9804 u), which can indeed influence its superconducting properties. When bismuth is cooled to very low temperatures, it can exhibit superconductivity with a critical temperature (Tc) around 10^-5 K (extremely low).

The superconducting edge, or the boundary between the superconducting and normal states, can be influenced by the mass of bismuth. In general, the superconducting state is characterized by the formation of Cooper pairs, which are pairs of electrons that behave as a single entity.

Electron Spin-Wave Vortices

In a superconducting material, the application of a magnetic field can lead to the formation of vortices, which are topological excitations that can be thought of as " whirlpools" of superconducting current. These vortices can be composed of electron spin waves, which are collective excitations of the electron spins.

In the case of bismuth, the high atomic mass and strong spin-orbit coupling can lead to a non-trivial topological character of the superconducting state. This might result in the formation of:

1. String-like vortices: These are one-dimensional topological defects that can form a string of electron spin-wave vortices on the surface of the bismuth sample.
2. Surface states: The surface of a topological superconductor like bismuth can host exotic surface states, such as Majorana fermions, which are zero-energy excitations that can be thought of as "half-electron" states.
