Classical limit of a scalar quantum field theory
S. Nagy, J. Polonyi
It is well known that a minimal distance emerges in quantum field theories owing to the need to regularize the UV divergences. The macroscopical limit at large minimal distance, we…

First order phase transition with functional renormalization group method
S. Nagy, J. Polonyi
The renormalization group method, more specifically the Wegner-Houghton equation, is used to find first order phase transitions in a simple scalar field theory with a polynomial po…
