Free energy of the gas of spin 1/2 fermions beyond the second order and the Stoner phase transition
Oskar Grocholski, Piotr H. Chankowski
Applying the previously developed systematic thermal (imaginary time) perturbative expansion to the relevant effective field theory we compute the free energy of the diluted ga…

Perturbative computation of thermal characteristics of the Stoner phase transition
Oskar Grocholski, Piotr H. Chankowski
We apply the thermal (imaginary time) perturbative expansion to the relevant effective field theory to compute characteristics of the phase transition to the ordered state which ca…
