There was a former PSE member who used to skip all of them except the ones that had tags in the set {QFT, mathematical physics} where he voted LO regardless of whether or not it actually ought to have been closed
In my experiences, the foreigners in my (internationally oriented) degree are more talkative/fun than most Germans, but that's also because they (1) may already have friends so are not really on the lookout for new ones (2) don't speak English too well in some cases
Firstly, my sincere apologies to all quantum computing students, I mean no disrespect, but we were amazed by the first Compact Disc and Integrated Chip, but eventually we took them for granted, and I'd imagine if the quantum computer ever works on an everyday level, the same thing will happen to...
@ShingLau What do you mean by "argue"? Professors may be willing to discuss their field of study with you, but they will not spend their time correcting your wrong notions or debating what they consider "basic" knowledge.
@KyleKanos I prefer to allow someone else to write an answer and then comment on it. If I feel strongly that inappropriate answers are getting attention then I'm motivated to write my own.
@0celo7 also I'll be going back home to nyc in a few days so I can grab my desktop and mod skyrim on that; I have a gig back home so I can use that as an excuse hehe
I meant disgusting the sense that it makes me feel a little nauseous to actually watch it when it gets really bad. Not in the sense that I find the concept of UFC fighting disgusting (I do find it dumb).
@0celo7 Mostly for reducible constraints, one finds that the "naive" BRST cohomology still contains functions of the ghosts and is not the proper algebra of gauge-invariant functions. In those cases, introducing further extra variables - the ghosts-of-ghosts - can yield the correct BRST cohomology.
@0celo7 That is indeed from QoGS, and related to "higher gauge theory" because one can also think of reducible constraints as those with non-trivial gauge-of-gauge transformations ;)
@0celo7 Because all the papers on this report to see the phase transition with ridiculuously small lattices. I basically can't reproduce the result of an entire decade :P
@ACuriousMind Do you have the book by Thijssen by any chance (Computational Physics)? Not that my expertise is in any way in the kind of stuff you're doing but I've read parts of the book and seem to remember that there was a chapter on gauge field theories there (that said, that's the chapter I didn't read).
And I've also tried another algorithm for the simulation, and it gives the same results - I must be doing something very basic wrong that's not specific to the algorithm, but, well, I can't find it.
Or it's not wrong and there is a difference between my situation and the situation in these papers that I'm not seeing.
@FenderLesPaul I had a random idea...in a string theory book I read, the authors showed how to construct a Lorentz metric out of a Riemannian one using a vector field.
Because what he might be saying is that since $M$ is paracompact we have a Riemannian metric $k$. Then there must be such a vector $t^a$ so we may construct $g$.
