As an occupation, I'm a mathematical physicist, studying string theory and quantum field theory.
I've developed as a hobby a few Cocoa (Touch) apps. The largest one so far is spires.app, which manages articles and metadata downloaded from the arXiv eprint server, the inspire database, and the journal websites.
I'm also interested in many other things, which is why I ask questions in various StackExchange sites ...

Instanton Moduli Space with a Surface Operator Satoshi, do you know you can formally accept the answer by clicking the big white check mark at the left of the answer? |

Any use for $F_4$ in hep-th? Wasn't Romans' F(4) the super algebra F(4)? |

Uniqueness of supersymmetric heterotic string theory Ah, thank you. Could you edit your answer accordingly (sorry for my mistake in my original question)? I'll accept yours immediately. |

Other processes than formal power series expansions in quantum field theory calculations Also note that this asymptotic series proves to be extremely precise, e.g. the theoretical result for $g-2$ calculated in this series agrees with the experiment to 10 significant digits. See en.wikipedia.org/wiki/Anomalous_magnetic_dipole_moment |

Uniqueness of supersymmetric heterotic string theory And could you suggest me where it is shown that these two solutions are unique? That was my question. |

Uniqueness of supersymmetric heterotic string theory Don't you need c=24k for modular invariance? |

Uniqueness of supersymmetric heterotic string theory Do they satisfy the required specific "nice properties" to construct a heterotic string? |

Does 4D N = 3 supersymmetry exist? Has anybody read Chap. 12 of ["Harmonic Superspace" ebooks.cambridge.org/ebook.jsf?bid=CBO9780511535109], titled "N=3 super Yang-Mills theory"? I've never understood whether what they describe is N=3 or N=4 |

Why are some solitons formed from bosonic fields fermionic? Additional comment is that even in 4d, the WZW term can make a soliton constructed from scalar fields alone fermionic; the skyrmion becoming a baryon when the number of color is odd is the typical example. In a sense the Lagrangian in this case has a term which produces long-range phase. |
