Effect of droplet configurations within the functional renormalization group of the Ising model approaching the lower critical dimension
Ivan Balog, Lucija Nora Farkaš, Maroje Marohnić +1
We explore the application of the nonperturbative functional renormalization group (NPFRG) within its most common approximation scheme based on truncations of the derivative expans…

Approach to the lower critical dimension of the theory in the derivative expansion of the Functional Renormalization Group
Lucija Nora Farkaš, Gilles Tarjus, Ivan Balog
We revisit the approach to the lower critical dimension in the Ising-like theory within the functional renormalization group by studying the lowest approximation…
