Analog Hawking radiation FWIF John Baez had a blog post over at Azimuth about this topic: johncarlosbaez.wordpress.com/2011/11/28/liquid-light |

Quantum Field Theory from a mathematical point of view If I had to guess I'd say that "vague and speculative" may be considered to be "polemical". I remember writing something along these lines two years ago at the nCafe :-) (golem.ph.utexas.edu/category/2009/10/…) |

Extensions of DHR superselection theory to long range forces Thanks for the tip! I am curious about Bucholz's conlcusion "Origin of infrared difficulties can be traced back to unreasonable idealization of observations covering all of Minkowski space". I remember asking about this idealization in all QFT calculations in an introductory class, but had no idea that this would reappier in such a context :-) |

Extensions of DHR superselection theory to long range forces Well, that's a good start :-) But I'll leave the question open for now. |

Status of local gauge invariance in axiomatic quantum field theory @Urs, thanks, so a better question to ask would be how to classify nets coming from certain quantization procedures of gauge theories, or maybe to classify gauge theories which produce Haag-Kastler nets. BTW, I think it is also possible to chat in certain chat rooms here, which would be - maybe - easier for a longer conversation like the one that happened here. |

Status of local gauge invariance in axiomatic quantum field theory Well, maybe, but how? But please note that the question is not "do we need local gauge symmetry" but "do we need local gauge symmetry in the framework of AQFT", with the latter being somewhat more precise than the former. |

Status of local gauge invariance in axiomatic quantum field theory Ok, maybe I should explain my own viewpoint of what AQFT is: That it should be able to describe the same phenomena as the standard model. |

What do theoretical physicists need from computer scientists? @Aaron Sterling: My suggestion is to have a stronger focus even in soft questions in order to adress one area of expertise, not many. Office solutions (word processing etc.) are a whole different topic than numerical algorithms, with people in one area rarely ever talking to people in the other area. (I certainly don't suggest to delete the question, or any answers, I think it is a very good example for a soft question for this private beta phase.) |

What do theoretical physicists need from computer scientists? I think the question is still too soft in the sense that it asks about very different topics. Answers could be about office solutions like small scale document management systems (like the one behing the arXiv), computational physics and numerical mathematics (e.g. open source libraries for fast sparse linear algebra not in FORTRAN), visualization, gui design, web page design, algorithm development and analysis (which can be and is done by people who have never written a program that compiled in their entire carreer), high performance computing and data analysis (like for the LHC) etc. etc. |
