AbstractIn this paper, we tentatively assign the $$P_{c}(4312)$$ P c ( 4312 ) to be a $$\bar{D}\Sigma _{c}$$ D ¯ Σ c molecular state with quantum number $$J^{P}=\frac{1}{2}^{-}$$ J P = 1 2 - , and calculate its magnetic moment using the QCD sum rule method in external weak electromagnetic field. Starting with the two-point correlation function in external electromagnetic field and expanding it in power of the electromagnetic interaction Hamiltonian, we extract the magnetic moment from the linear response to the external electromagnetic field. The numerical value of the magnetic moment of $$P_{c}(4312)$$ P c ( 4312 ) is $$\mu _{P_{c}}=1.75^{+0.15}_{-0.11}$$ μ P c = 1 . 75 - 0.11 + 0.15 .

Dirac Quantization

A generalization of the pseudoclassical action of a spinning particle in the presence of an anomalous magnetic momentum is given. The action is written in reparametrization and supergauge invariant form. The Dirac quantization, based on the Hamiltonian analyzes of the model, leads to the Dirac-Pauli equation for a particle with an anomalous magnetic momentum in an external electromagnetic field. Due to the structure of first class constraints in that case, the Dirac quantization demands for consistency to take into account an operator’s ordering problem.

Heating Behavior

In this work, a sodium-cobalt oxide (NaxCo2O4) ceramic composite nanofiber was manufactured through electrospinning. The response of the fiber to external electromagnetic field was characterized to observe the heat generation in the fiber. In addition, we also measured the current passing through the fiber under the polarization of DC potential. It is found that the fiber has intensive heating behavior when it is exposed to the electromagnetic field. The temperature increases more than 5 degrees in Celsius scale only after 5 s exposure. The current – potential curve of the fiber reveals its dielectric behavior. It is concluded that this ceramic fiber has the potential to be used for hyperthermia treatment in biomedical engineering or for energy conversions.

The conversion of photons into axions in a periodic external electromagnetic field, i.e. the TEm0 mode, is considered in details by using Feynman methods. The differential cross-sections are given. It is shown that the lowest mode gives the main contribution to the considered process.
