Inhomogeneous condensation in effective models for QCD using the finite-mode approach
Achim Heinz, Francesco Giacosa, Marc Wagner +1
We use a numerical method, the finite-mode approach, to study inhomogeneous condensation in effective models for QCD in a general framework. Former limitations of considering a spe…
Inhomogeneous condensates in the parity doublet model
Achim Heinz
Within the parity doublet model coupled to the linear sigma model including vector mesons it is possible to describe vacuum properties of the low energy mesons and to achieve nucle…
Restoration of chiral symmetry in the large-N_c limit
Achim Heinz, Francesco Giacosa, Dirk H. Rischke
We study the large-N_c behavior of the critical temperature T_c for chiral symmetry restoration in the framework of the Nambu-Jona-Lasinio (NJL) model and the linear σ-model. While…
Phenomenological improvement of the linear- model in the large-N_c limit
Achim Heinz
The linear- model has been widely used to describe the chiral phase transition. Numerically, the critical temperature of the chiral phase transition is in agreement with…
Light tetraquark state at nonzero temperature
Achim Heinz, Stefan Struber, Francesco Giacosa +1
We study the implications of a light tetraquark on the chiral phase transition at nonzero temperature : The behavior of the chiral and four-quark condensates and the meson masse…
Role of the tetraquark in the chiral phase transition
Achim Heinz, Stefan Struber, Francesco Giacosa +1
We investigate the implications of a tetraquark field on chiral symmetry restoration at nonzero temperature. In order for the chiral phase transition to be cross-over, as shown by…
