dc.description.abstract | Dynamics of systems coupled to an environment are usually hard to obtain; their solutions rely on approximation, which may not be reliable in many cases. Here we use the Reaction coordinate mapping and the Quantum trajectories to study the dynamics of strongly interacting systems. We benchmark an own derived Lindblad master equation for the Spin-Boson, in the dephasing limit, where the reaction coordinate mapping was applied. The master equation was unraveled with quantum trajectories, where a numerical improvement was found. The Lindblad master equation was used for a pair of 2 non-interacting qubits immersed in a bosonic bath. The Reaction coordinate map shows the presence of entanglement between the qubits and entanglement revival. Finally, the reaction coordinate was applied for a single electron transistor, getting the occupation of the dot in the non-equilibrium dynamics. (Text taken from the source) | eng |
dc.description.abstract | La dinámica de los sistemas acoplados a un entorno suele ser difícil de obtener; sus soluciones se basan en aproximaciones, que pueden ser no fiable en muchos casos. Aquí usamos el mapeo de coordenada de reacción y las trayectorias cuánticas para estudiar la dinámica de sistemas que interact´uan fuertemente. Se testeo una ecuaci´on maestra de Lindblad de derivacion propia para el sistema Spin-Boson en el límite de desfase, donde se aplicó el mapeo de coordenadas de reacci´on. La ecuaci´on maestra se desentra˜n´o con trayectorias cu´anticas, donde se encontr´o una mejora numérica. La ecuación maestra de Lindblad se utilizó para un par de qubits que no interactúan sumergidos en un baño bosónico. El mapa de coordenadas de reacción muestra la presencia de entrelazamiento entre los qubits y renacimiento del entrelazamiento. Finalmente, se aplic´o la coordenada de reacci´on para un transistor de un solo electrón, obteniendo la ocupación del punto quantico en la dinámica de no equilibrio. | spa |
