TY - JOUR AU - Pérez-Maldonado, M. T. AU - Monsivais, G. AU - Mulet, Roberto PY - 2017 TI - Redfield Dynamics of a Quantum Spherical Spin JF - Revista Cubana de Física; Vol 34 No 2 (2017) KW - N2 - The temporal evolution of a quantum spherical spin in contact with a thermal bath is studied by solving the exact Redfield equation, in order to evaluate the effect of the frequently used Lindblad approximation. This simple model can be used as a starting point for the study of more complex open quantum systems. Significant discrepancies are observed for short times. In the equilibrium state both models give identical results, as expected. UR - https://www.revistacubanadefisica.org/index.php/rcf/article/view?path=
