@article{Gaitanos2013MomentumDM, title={Momentum dependent mean-field dynamics of compressed nuclear matter and neutron stars}, author={Theodoros Gaitanos and Murat M. Kaskulov}, journal={Nuclear Physics}, year={2013}, volume={899}, pages={133-169} }

Abstract Nuclear matter and compact neutron stars are studied in the framework of the non-linear derivative (NLD) model which accounts for the momentum dependence of relativistic mean-fields. The generalized form of the energy–momentum tensor is derived which allows to consider different forms of the regulator functions in the NLD Lagrangian. The thermodynamic consistency of the NLD model is demonstrated for arbitrary choice of the regulator functions. The NLD approach describes the bulk…
