Critical Exponents from Dimensional Variation
H. Ballhausen
Recent work on exact renormalization group flow equations has pointed out the possibility to study critical phenomena in continuous dimension D of space. In an investigation of the…

Direct Calculation of the Critical Effective Potential
H. Ballhausen
The critical effective potential is the nonperturbative part of the effective action at a phase transition. It equals the scale invariant effective average potential and can be cal…

The Effective Average Action Beyond First Order
H. Ballhausen
A derivative expansion of the effective average action beyond first order yields renormalization group functional flow equations which are used for the computation of critical expo…
