Quantum-classical transition in the Caldeira-Leggett model
J. Kovacs, B. Fazekas, S. Nagy +1
The quantum-classical transition in the Caldeira-Leggett model is investigated in the framework of the functional renormalization group method. It is shown that a divergent quadrat…
Asymptotic safety in the sine-Gordon model
J. Kovacs, S. Nagy, K. Sailer
In the framework of the functional renormalization group method it is shown that the phase structure of the 2-dimensional sine-Gordon model possesses a nontrivial UV fixed point wh…
Optimized regulator for the quantized anharmonic oscillator
J. Kovacs, S. Nagy, K. Sailer
The energy gap between the first excited state and the ground state is calculated for the quantized anharmonic oscillator in the framework of the functional renormalization group m…
Renormalization of QCD_2
J. Kovacs, S. Nagy, I. Nandori +1
The low energy infrared scaling of the multi-color 2-dimensional quantum chromodynamics is determined in the framework of its bosonized model by using the functional renormalizatio…
