El Grupo de Información y Termodinámica Cuántica de la Universidad de Granada les invita al siguiente seminario: Ponente: Rafael A. Molina Fernández. Instituto de Estructura de la Materia, CSIC, Madrid. Título: From integrability to chaos in quantum Liouvillians. Resumen: The dynamics of open quantum systems can be described by a Liouvillian, which in the Markovian approximation fulfills the Lindblad master equation. We present a family of integrable many-body Liouvillians based on Richardson-Gaudin models with a complex structure of the jump operators. Making use of this new region of integrability, we study the transition to chaos in terms of a two-parameter Liouvillian. The transition is characterized by the spectral statistics of the complex eigenvalues of the Liouvillian operators using the nearest neighbor spacing distribution and by the ratios between eigenvalue distances. Fecha y hora: Miércoles 24 de Noviembre, 12:00. Lugar: Laboratorio de Computación del Área de Física de la Materia. Planta baja del edificio de Física. Facultad de Ciencias.
