Bardeen solution with a cloud of strings
نویسندگان
چکیده
In this paper we present a Bardeen solution surrounded by cloud of strings fluid. We show how model has the same event horizon characteristic as solution. However, parameter make singular at origin. also analyze from thermodynamic point view. calculate system's state function, enthalpy, temperature, and other potentials, function entropy. By analyzing coefficients, that presents three distinct phases, two which are stable one is unstable. These phases could be best visualized using plot Gibbs free energy versus temperature. Finally, critical exponents find they those found in Van der Walls theory.

Nonperturbative Adler-Bardeen Theorem
1.1 Anomalies in QFT. The chiral anomaly appears as a quantum correction to the conservation of the axial current for massless fermions. A crucial property is the anomaly nonrenormalization, which says that the chiral anomaly is given exactly by its lower order contribution. This property was proved first for QED4 in [AB] in the well known Adler-Bardeen Theorem: it was shown that there is a dra...

The critical temperature and gap solution in the Bardeen-Cooper-Schrieffer theory of superconductivity
The paper studies the problem of numerical approximations of the critical transition temperature and the energy gap function in the Bardeen-CooperSchrieffer equation arising in superconductivity theory. The positive kernel function leads to a phonon dominant state at zero temperature. Much attention is given to the equation defined on a bounded region. Two discretized versions of the equation w...
