TL;DR
This paper derives an analytical formula for the zero-temperature conductance of a parallel T-shaped double quantum dot system, revealing the influence of the non-connected dot on overall conductance.
Contribution
It provides a new analytical expression linking conductance to electron count in the dots, highlighting the role of the disconnected dot.
Findings
Conductance depends on the total electron number in both dots.
The non-connected dot significantly affects the system's conductance.
Results align with and extend previous literature findings.
Abstract
We analyze the zero temperature conductance of a parallel T-shaped double quantum dot system. We present an analytical expression for the conductance of the system in terms of the total number of electrons in both quantum dots. Our results confirm that the system's conductance is strongly influenced by the dot which is not directly connected to the leads. We discuss our results in connection with similar results reported in the literature.
