This paper studies the important concepts in the fundamental optimization of mass and thermal properties of strong interactions based on quantum approximate operators. It explores and analytically calculates the radial part of the Schrödinger equation at finite temperature using the two intertwined spaces based on the Wick ordering method in the Bernoulli Potential. We provide analytical expressions for the ground state energy eigenvalues to define the zeroth approximation. Bernoulli potential refers to some of the potential types that are returned to the Bernoulli series. The method presented in this study allows us to rewrite some of the exponential potentials simply to even power levels in the Bernoulli series. Given that the Hulthen potential is a modified form of main hadronic interaction potentials, it is used to calculate the bound state mass and properties of hadronic atoms such as π-atoms, κ-atoms or various hadronic structures with positive/negative and heavy/light quark bound states such as 〖D_s〗^+,〖B_c〗^+,〖〖〖B_ 〗^+,D^+ ,D〗_ 〗^(*+) at finite temperatures. The main goal of this research is to the combined quantum operators and two intertwined spaces within the Bernoulli expansion to determine the best approximation of upsilon meson mass and thermal properties.

Recent progress in high-technology equipment enables the fabrication of quantum dots such as GaAs, and GaAlAs confining a finite number of excitons and allowing for control of the properties of quantum dots. Biexciton quantum dots are the simplest example that can be used to upgrade optoelectronics technologies. This theoretical research investigates a model of the biexciton state in the strongly oblate ellipsoidal quantum dot with the relativistic corrections of mass and Hamiltonian in the framework of the quantum field theory due to the importance of the relativistic effect for this type of quantum dot shapes. The Sturmian function transformation and Wick ordering method to calculate the vacuum state energy eigenvalue of the biexciton system are utilized. Based on the relativistic behavior of interactions, the mass corrections to the Hamiltonian are defined. Dependence of the relativistic mass on the distances between electrons and the constituent mass to the coupling constant is obtained. The results show that as increasing quantum dot size, the relativistic mass and Hamiltonian corrections terms decrease.

A theoretical search is conducted to determine the mass spectra and wave functions of the higher di-molecular type of meson states X(3872)"," Y(4140),Z(4430),X(5568) in the Hellmann potential, with relativistic effects and corrections. Femtoscopic J/ψ bound states have essential concepts in high-energy physics, especially in creating two-point correlation functions for the hadronic molecule channels that build the T_cc state. We analytically calculated the radial part of the Schrödinger equation using the transformation to relativistic space using the normal ordering operators. The excited states of eigenenergy are obtained. The constituent mass of the di-molecular type of mesons was determined, which appears due to relativistic effects. It is informative to describe strong interactions and bound states mechanisms using quantum field theory ideas and quantum mechanics. At the conclusion of this research, we will provide advancements in the higher meson states mass spectra in the relativistic limit. The results provide satisfaction in comparison with experimental data and the work of other researchers.
