    "abstract": "A novel method is introduced in order to treat the dissipative dynamics of\nquantum systems interacting with a bath of classical degrees of freedom. The\nmethod is based upon an extension of the Nos\\`e-Hoover chain (constant\ntemperature) dynamics to quantum-classical systems. Both adiabatic and\nnonadiabatic numerical calculations on the relaxation dynamics of the\nspin-boson model show that the quantum-classical Nos\\`e-Hoover chain dynamics\nrepresents the thermal noise of the bath in an accurate and simple way.\nNumerical comparisons, both with the constant energy calculation and with the\nquantum-classical Brownian motion treatment of the bath, show that the\nquantum-classical Nos\\`e-Hoover Chain dynamics can be used to introduce\ndissipation in the evolution of a quantum subsystem even with just one degree\nof freedom for the bath. The algorithm can be computationally advantageous in\nmodeling, within computer simulation, the dynamics of a quantum subsystem\ninteracting with complex molecular environments.",
