Effective field theory for He-IV
J. M. Carmona, S. Jimenez, J. Polonyi +1
We introduce an effective scalar field theory to describe the He-IV phase diagram, which can be considered as a generalization of the XY model which gives the usual lambda-transiti…

Spinodal Instability and Confinement
Janos Polonyi
It is pointed out that inhomogeneous condensates or spinodal instabilities suppress the propagation of elementary excitations due to the absorptive zero mode dynamics. This mechani…

Internal space renormalization group for the Luttinger model
Janos Polonyi, Franck Stauffer
The absence of fermionic, asymptotical one-particle states in the Luttinger model raises the suspicion that the interactions are actually strong at the vicinity of the Fermi points…
