" Interference and correlations in two-level transport through quantum 
dots"


Abstract

	Two-level quantum dots coupled to two reservoirs with spinless 
electrons with no particular symmetries can be mapped exactly to a 
generalized spinful single-impurity Anderson model.  We give a general 
characterization of charge occupation numbers and linear conductance in 
regime interlevel Coulomb repulsion by employing various analytical 
techniques developed for the local moment regime of the Anderson model. 
  Implications for population inversion, transmission phase lapse and 
orbital Kondo effect in quantum dots are discussed.
