| In this Talk, we study quantum impurity models in relation with the Coulomb blockade phenomenon and dissipation effects. First, we theoretically investigate dissipation stemming from a resistance and discuss dissipative many-body quantum phenomena, with applications in electron and photonic systems. Second, dissipation in quantum impurity models gives rise to the Korringa-Shiba relation which has important implications for mesoscopic transport, resulting in a universal charge relaxation resistance. We illustrate this concept through the quantum RC circuit. |
