| contents | We present a novel approach for calculating the Coulomb Blockade Phase Diagram (CBPD) in the experimentally accessible strong coupling regime of a single-electron transistor (SET). Our method utilizes the Path Integral Monte Carlo (PIMC) technique to accurately compute the Coulomb oscillation of the Differential Capacitance (DC). Furthermore, we investigate the impact of the gate voltage and temperature variations on the DC, thereby gaining insights into the system's behaviour. As a result, we propose a method to calculate the Coulomb Blockade Boundary Line (CBBL) and demonstrate its efficacy by setting the visibility parameter to $10\%$. The resulting boundary line effectively defines the transition between the Coulomb and non-Coulomb blockade regimes, thereby enabling the construction of a comprehensive CBPD. |
