We study chiral symmetry restoration by analyzing thermal properties of QCD's (pseudo-)Goldstone bosons, especially the pion. The meson are obtained from spectral densities mesonic imaginary-time correlation functions. To obtain functions, we solve Dyson-Schwinger equations and inhomogeneous Bethe-Salpeter in leading symmetry-preserving rainbow-ladder approximation. In limit, pion its partner s...

A bstract We study the competition between p-wave and p+ip superfluid solutions in a holographic model with applied magnetic field intensity H . find that when is turned on, both grand potential critical temperature of solution are shifted, while only slightly affected. Combining effect back reaction parameter b, we build − T phase diagrams slit region phase. The zero (or finite) value at start...

We review the recent proposal that the most fascinating brain properties are related to the fact that it always stays close to a second order phase transition. In such conditions, the collective of neuronal groups can reliably generate robust and flexible behavior, because it is known that at the critical point there is the largest abundance of metastable states to choose from. Here we review t...
