Neutron matter at finite temperature
The nuclear equation of state plays a central role in the physics of neutron stars and core-collapse supernovae. Renormalization group methods coupled with effective field theory offer a systematic approach to nuclear matter: For low-momentum interactions Vlow k with cutoffs around 2 fm−1, the strong short-range repulsion in conventional nucleon-nucleon (NN) interactions and the tensor force ar...
متن کاملBreaking of a metastable string at finite temperature
We consider the phase transition of a string with tension ε1 to a string with a smaller tension ε2 at finite temperature. For sufficiently small temperatures the transition proceeds through thermally catalyzed quantum tunneling, and we calculate in arbitrary number of dimensions the thermal catalysis factor. At ε2 = 0 the found formula for the decay rate also describes a break up of a metastabl...
متن کاملN ov 2 00 7 Neutron matter at finite temperature
We calculate the neutron matter equation of state at finite temperature based on low-momentum twoand three-nucleon interactions. The free energy is obtained from a loop expansion around the Hartree-Fock energy, including contributions from normal and anomalous diagrams. We focus on densities below saturation density with temperatures T 6 10MeV and compare our results to the model-independent vi...
متن کاملStrange mesons in nuclear matter at finite temperature
We study the properties of K and K̄ mesons in nuclear matter at finite temperature from a chiral unitary approach in coupled channels which incorporates the sand p-waves of the kaon-nucleon interaction. The in-medium solution accounts for Pauli blocking effects, mean-field binding on all the baryons involved, and π and kaon self-energies. We calculate K and K̄ (off-shell) spectral functions and s...
متن کاملCharge and stability of strange quark matter at finite temperature
By means of the quark mass densityand temperaturedependent model, it is found that the negative charge and the higher strangeness fraction are in favor of the stability of strange quark matter at finite temperature. A critical baryon number density nBc has been found. The strange quark matter is unstable when nB < nBc. The charge and strangeness fraction dependence of stability for strange quar...
