Equivalence of Many-Gluon Green Functions in Duffin-Kemmer-Petieu and Klein-Gordon-Fock Statistical Quantum Field Theories
We prove the equivalence of many-gluon Green functions in DuffinKemmer-Petieu (DKP) and Klein-Gordon-Fock (KGF) statistical quantum field theories. The proof is based on the functional integral formulation for the statistical generating functional in a finite-temperature quantum
Single-Particle Green Function Approach and Correlated Atomic or Molecular Orbitals
In this paper, we propose a generic and systematic approach for study of the electronic structure for atoms or molecules. In particular, we address the issue of single particle states, or orbitals, which should be one of the most important aspects of a quantum many-body theory. W
On the Iterated Green Functions on a Bounded Domain and Their Related Kato Class of Potentials
We use the results of Zhang [15, 16] and Davies [7] on the behavior of the heat kernel p(t, x, y) on a bounded C domain D to find again the result of Grunau-Sweers [9] concerning the estimates of the iterated Greens functions Gm,n(D). Next, we use these estimates to characterize,
More accurate Jensen-type inequalities for signed measures characterized via Green function and applications
In this paper we derive several improved forms of the Jensen inequality, giving the necessary and sufficient conditions for them to hold in the case of the real Stieltjes measure not necessarily positive. The obtained relations are characterized via the Green function. As an appl
On Smoothness of the Green Function for the Complement of a Rarefied Cantor-Type Set
Smoothness of the Green functions for the complement of rarefied Cantortype sets is described in terms of the function φ(δ) = (1/ log 1 δ ) that gives the logarithmic measure of sets. Markov’s constants of the corresponding sets are evaluated.
Dyadic Green Function/MoM based Method for the Analysis of Electromagnetic Fields inside a Lossy, Multilayered Spherical Head Phantom Excited By RF Coil
F. Liu, S. Crozier, B. Xu, I. Gregg School of Information Technology and Electrical Engineering, Brisbane, Queensland, Australia Synopsis The precise evaluation of RF coil-tissue interactions and the electromagnetic fields (EMFs) inside biological samples is becoming an increasin
Thermal Green Functions at Zero Energy
The thermal expectation values of all possible bosonic generalised retarded functions evaluated at zero energy are studied. The relationship of such functions to calculational schemes, technical problems and physical applications is outlined. It is then shown that all generalised
Punicalagin Green Functionalized Cu/Cu2O/ZnO/CuO Nanocomposite for Potential Electrochemical Transducer and Catalyst
A novel ternary Punica granatum L-Cu/Cu2O/CuO/ZnO nanocomposite was successfully synthesised via green route. In this work, we demonstrate that the green synthesis of metal oxides is more viable and facile compare to other methods, i.e., physical and chemical routes while present
The zero-momentum limit of thermal green functions
The zero momentum limit of thermal self-energies calculated in perturbation theory depends on the order in which the time and the space components of the momentum are taken to zero. We show that this is an artifact of the perturbative calculation, and in fact the limit is well-de
