In this study, we examine the thermoelectric characteristics of a system consisting of two topological superconducting nanowires, each exhibiting Majorana zero modes at their ends, connected to leads within an interferometer configuration. By employing Green’s function formalism, we derive the spectral properties and transport coefficients. Our findings indicate that bound states in the continuum (BICs) manifest in symmetric setups, influenced by the length of the wires and coupling parameters. Deviations of the magnetic flux from specific values transform BICs into quasi-BICs with finite width, resulting in conductance antiresonances. The existence and interplay of Majorana zero modes enhance thermoelectric performance in asymmetric configurations. Modulating the magnetic flux transitions BICs into quasi-BICs significantly enhances the Seebeck coefficient and figure of merit, thereby proposing a strategy for optimizing thermoelectric efficiency in systems based on Majorana zero modes.
