                             "Quantum dissipative systems
                via bosonisation of fermion gas-impurity models"

        Kivonat: Solvable models of one dimensional fermion gases interacting
        with magnetic impurities can be interpreted as quantum dissipative 
systems
        via bosonisation mapping techniques. The most famous instance is the
        transcription between the spin-1/2 anisotropic Kondo model, and the
        so-called spin-boson model (a spin-1/2 system with ohmic coupling to 
an
        oscillator bath). We review this construction, and extend it to 
several new
        cases. These include an elliptic version of the Kondo model, and a
        three-component fermion gas model. The corresponding quantum 
dissipative
        systems will be described, and prospects for the analysis of their
        properties using the exact fermion gas solution will be discussed.
