Dynamical and topological propertiesof periodically driven nanostructures – propiedades din\u00e1micas y topol\u00f3gicasde nano-estructuras con campos acen esta tesis estudiamos las propiedades de sistemas nanosc\u00f3picos acoplados a campos el\u00e9ctricos y magn\u00e9ticos ac.Durante la primera secci\u00f3n se estudia el caso de dobles puntos cu\u00e1nticos en presencia de campos magn\u00e9ticos ac. Concretamente, se estudia la existencia de localizaci\u00f3n de carga y esp\u00edn, y su relaci\u00f3n con las simetr\u00edas discretas de paridad y paridad generalizada.Al final de la secci\u00f3n estudiamos la relaci\u00f3n entre observables y localizaci\u00f3n en un sistema abierto. Concretamente desarrollamos una ecuaci\u00f3n maestra, incluyendo contactos met\u00e1licos, y demostramos como la localizaci\u00f3n de carga est\u00e1 relacionada con el bloqueo de la corriente.Finalmente, consideramos el doble punto cu\u00e1ntico como un sistema donde generalizar el estudio de fases geom\u00e9tricas realizado en los a\u00f1os 80 por m. Berry, analizando la influencia de los grados de libertad espaciales e inhomogeneidades magn\u00e9ticas.En la segunda secci\u00f3n de la tesis se desarrolla la teor\u00eda de floquet-bloch, para el estudio de las propiedades topol\u00f3gicas de redes acopladas a campos ac el\u00e9ctricos. Se propone una extensi\u00f3n de la cl\u00e1sica teor\u00eda topol\u00f3gica de bandas, incluyendo una primera zona de brillouin extendida, llamada primera zona de floquet-brillouin (ffbz) y el operador de floquet.Como resultado, demostramos que la clasificaci\u00f3n topol\u00f3gica completa es posible en t\u00e9rminos de una dimensi\u00f3n superior al sistema est\u00e1tico, y que los reg\u00edmenes adiab\u00e1tico\/diab\u00e1tico son an\u00e1logos a un sistema de wannier-stark en esta dimensi\u00f3n superior, en los l\u00edmites de campo d\u00e9bil\/fuerte respectivamente.En la \u00faltima secci\u00f3n de la tesis se considera el caso de electrones en una red hexagonal, acoplados a un campo ac el\u00e9ctrico en el plano. Se demuestra como las diferentes configuraciones de campo el\u00e9ctrico permiten dos efectos; a) la fusi\u00f3n de conos de dirac, y b) la realizaci\u00f3n del efecto hall cu\u00e1ntico an\u00f3malo.El primer efecto se debe a la anisotrop\u00eda en los t\u00faneles inducida por el campo, lo cual hace que los conos de dirac se muevan, mientras que el segundo efecto se debe a la ruptura de la simetr\u00eda de inversi\u00f3n de tiempo debido a la polarizaci\u00f3n del campo el\u00e9ctrico.<\/p>\n
