Feb 26, 2017 at 20:43 | comment | added | anon | @Everett, does this nonanalyticity have any implication? I believe analyticity is guaranteed at all other Matsubara points, both bosonic and fermionic. | |
Feb 26, 2017 at 17:38 | comment | added | AccidentalFourierTransform | would it be accurate to say that any system without mass-gap has a singularity at ω=0? | |
