SUMMARY

The discussion centers on the concept of anyonic strings, which are 2-dimensional objects related to topological quantum field theories (TQFTs) and Chern-Simons theory. The participants express skepticism towards supersymmetry, emphasizing that anyons arise from non-trivial representations of the braid group in 2+1 dimensions, with no equivalent in higher dimensions. Key resources shared include articles on exotic statistics for strings and the fractional quantum Hall effect, highlighting the intersection of anyons and string theory.

PREREQUISITES
  • Understanding of anyons and their properties in 2+1 dimensions
  • Familiarity with topological quantum field theories (TQFTs)
  • Knowledge of Chern-Simons theory
  • Basic concepts of quantum mechanics, particularly in condensed matter physics
NEXT STEPS
  • Research "Topological Quantum Computation" for insights into quantum computing applications
  • Explore "Non-Abelian Anyons and Topological Quantum Computation" for advanced understanding of anyons
  • Investigate "Fractional Quantum Hall Effect" and its implications in condensed matter physics
  • Read "Exotic Statistics for Strings in 4d BF Theory" for a deeper dive into string theory and statistics
USEFUL FOR

Researchers and students in theoretical physics, particularly those focusing on quantum mechanics, string theory, and topological systems. This discussion is beneficial for anyone exploring the connections between anyons, TQFTs, and quantum computation.

Anyon are particular 2 dimensionsional objects and so is the worldsheet critical superstrings. But given that those 2 are extemely fashionable nowadays, and they happen in this dimension, I am extremely surprised to find that anyone didn't try anyonic strings. That is, instead of supersymmetric, one would get an anyon relation.

Anyway, I relly don't like supersymmetry because they are not generic enough, because they just relate fermions and bosons. Personal taste, really. Maybe relations between anyons and supersymmetry might have a relation. I don't know.

Any hint?

Well, remember first that anyons arise due to the non-trivial representations of the permutation (or better: braid) group in 2+1 dimensions. In that same train of thought it follows that there are no anyons in higher dimensions. At least not in the same literal sence.

On the other hand, anyons are closely related to topological quantum field theories, Chern-Simons theory in particular. TQFT's in higher dimensions are indeed employed in string theory, although don't ask me in what way.
 
Sure, you are right. I had this mental image of anyons in a plane, because of the usual examples in condensed matter QM, where time is just a paramter. I totally forgot that the time dimension was not being counted. So you are right, if there is any relation with a string theory, it should be a topological one.

Yes, after your tip, I've found some interesting things:

Funny that you mention those. I'm actually starting my PhD on topological systems and its relation to topological quantum computation, with emphasis on the fractional quantum Hall effect. I recommend this review article in particular:
