Orellana Física, Astronomía y Matemáticas Quantum dots Electronic transport Quantum interference In this article we study the electronic transport through a triple quantumdot molecule parallelcoupled toleads under a magnetic field. Analytical expressions are obtained for both the conductance and total density ofstates for the molecule in equilibrium at zero temperature. As a result of quantum interference of resonancesbelonging to different channels, this configuration exhibits bound states in the continuum (BICs). We examinethe broadenings of the molecular states around the conditions under which BICs occur, finding longlived statesextremely robust under variations of the magnetic flux. 2006 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46436531 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.3B Vol.36 |
