One point which Wen is particularly excited about is that fermions can appear as quasiparticles in local bosonic lattice systems. |
|
The biggest problem with bosonic string theory is that the lowest energy state was a tachyon, or a particle mode with negative mass squared. |
|
Quarks have bosonic partners called squarks, neutrinos have sneutrinos and so on. |
|
Supersymmetric theories are good places to look for exotic matter in the form of fermionic superpartners of bosonic particles that carry forces. |
