E.H. Martins Ferreira, M.C. Nemes, H.A. Weidenmueller
TL;DR
This paper investigates how embedding a quantum dot can significantly enhance persistent currents in a system, although the paper has been withdrawn due to a critical error in its assumptions.
Contribution
The study proposes a method to enhance persistent currents using an embedded quantum dot, highlighting the potential impact on quantum transport.
Findings
Potential enhancement of persistent current with quantum dot embedding
Identification of critical assumptions affecting results
Withdrawal due to fundamental error in assumptions
Abstract
This paper has been withdrawn by the authors due to crucial error on assumption in Eq. 2. We cannot assume v_R and v_L to be equal or even have the same sign.
