The phase diagram of the massive Gross-Neveu model, revisited
Oliver Schnetz, Michael Thies, Konrad Urlichs
The massive Gross-Neveu model is solved in the large N limit at finite temperature and chemical potential. The phase diagram features a kink-antikink crystal phase which was missed…
On the mean-field spherical model
Michael Kastner, Oliver Schnetz
Exact solutions are obtained for the mean-field spherical model, with or without an external magnetic field, for any finite or infinite number N of degrees of freedom, both in the…
Calculation of the phi^4 6-loop non-zeta transcendental
Oliver Schnetz
We present an analytic calculation of the first transcendental in phi^4-Theory that is not of the form zeta(2n+1). It is encountered at 6 loops and known to be a weight 8 double su…
Generating Functions for Multi-j-Symbols
Oliver Schnetz
A formula is derived that provides generating functions for any multi-j-symbol, such as the 3-j-symbol, the 6-j-symbol, the 9-j-symbol, etc. The result is completely determined by…
