Abstract
We study the pseudospin Kondo effect in laterally coupled double quantum dots using the slave-boson mean-field theory. We find that the exotic pseudospin Kondo effect appears when a coherent indirect coupling with parameter $\ensuremath{\alpha}$ is present through the common reservoirs. When $0l\ensuremath{\mid}\ensuremath{\alpha}\ensuremath{\mid}l1$, for finite interdot tunnel coupling, we obtain an asymmetric density of states due to pseduospin-dependent linewidth functions. The differential conductance reveals an additional structure in the split peaks caused by the interdot tunnel coupling because of the asymmetry of the density of states.
