Bottomonia correlators and spectral functions at zero and finite temperature
K. Petrov, A. Jakovac, P. Petreczky +1
We present preliminary studies of bottomonia spectral functions at zero and finite temperature using quenched anisotropic lattices. The heavy quark is treated within Fermilab appro…
Renormalization and resummation in field theories
A. Jakovac, Zs. Szep
Using resummation in perturbation theories at finite temperature or in non-equilibrium is unavoidable to obtain consistent results. Resummation, however, is often in conflict with…
Analytic determination of the T-μphase diagram of the chiral quark model
A. Jakovac, A. Patkos, Zs. Szep +1
Using a gap equation for the pion mass a nonperturbative method is given for solving the chiral quark-meson model in the chiral limit at the lowest order in the fermion contributio…
Effect of the scalar condensate on the linear gauge field response in the Abelian Higgs model
A. Jakovac, A. Patkos, Zs. Szep
The effective equations of motion for low-frequency mean gauge fields in the Abelian Higgs model are investigated in the presence of a scalar condensate, near the high temperature…
Dynamical resummation and damping in the O(N) model
A. Jakovac
A general real-time formalism is developed to resum the self-energy operator of broken symmetry scalar field theories in form of self-consistent gap equations for the spectral func…
Classical Limit in Scalar QFT at High Temperature
Antal Jakovac
It is shown that in a scalar quantum field theory at high temperatures we can compute even time dependent observables from an effective theory, which can be interpreted as a (nonlo…
