Abstract:
We consider transport through a multilevel interacting quantum dot (N-QD) in the Kondo regime. Using the Kotliar-Ruckentein slave boson approach (SBMFA) for an N-level Anderson model, we define effectively noninteracting quasiparticles of the SU(N) Kondo system (N = 2, 3, 4, 5, 6). Kondo resonance transmission coefficients determine linear noise describing quasiparticle partitioning. To discuss nonlinear conductance, susceptibilities, and shot noise in the strong coupling regime, we apply Fermi liquid theory with parameters expressed by susceptibilities of pseudofermions determined within SBMFA. Nonlinear shot noise is dominated by two-quasiparticle scattering. However, we demonstrate that for occupation regions distant from the electron-hole symmetry point, the role of three-body correlations must be considered.

The unit impulse or sample sequence is mathematically expressed as zero for all n values except at n=0, where it is one. The unit impulse sequence, denoted by δ(n), is the first difference of the unit step sequence, while the unit step sequence u(n) is the...
