Effective potential and resummation procedure to multidimensional complex cubic potentials for weak and strong coupling

Abstract: The method for the recursive calculation of the effective potential is applied successfully in case of weak coupling limit (g tend to zero) to a multidimensional complex cubic potential. In strong-coupling limit (g tend to infinity), the result is resumed using the variational perturbation theory (VPT). It is found that the convergence of VPT-results approaches those expected.

“…In [55] we propose a method of derivation which allow us to obtain a general integrals containing a product of two gamma functions with a monomial x m , with m ∈ N. Indeed, we show that: It is obvious that the application of (B.1) is not restricted to the present paper; many others possibilities follow in physics as well as in mathematics, see [55].…”

“…In recent years, the concept of pseudo-Hermiticity has attracted much attention on behalf of physicists [1][2][3][4][5][6][7][8][9]. The basic mathematical structure underlying the properties of pseudo-Hermiticity is revealed [3][4][5] and it has been found to be a more general concept then those of Hermiticity and PT -symmetry [10][11][12][13][14][15]. By definition, a linear operator H (here a Hamiltonian) acting in a Hilbert space H is called η-pseudo-Hermitian if it obeys to [3][4][5] ηH = H † η,…”
