, La brisure de symétrie du réseau est ce qui permet à la totalité de la population excitonique d'être captée par le piège. Dans ce contexte, nous avons démontré numériquement que la rapidité du processus d'absorption était intimement liée à l'interaction des deux paramètres physiques en jeu : ? et W . Nous avons ainsi pu observer l'existence d'une région critique dans l'espace des paramètres dans laquelle le temps d'absorption ? est fortement minimisé. Cette région est la preuve directe de la possibilité d'une interaction bénéfique entre le désordre et le piégeage. Pour tenter de comprendre la physique émergeant dans cette région, nous nous sommes essentiellement basés sur deux choses : nos connaissances du système en absence de désordre, mais aussi tous les comportements observés aux différents points asymptotiques de l'espace des paramètres. Ce faisant, nous pensons actuellement que des développements complémen-taires pourraient permettre de préciser encore plus notre compréhension de cette région. Nous prévoyons notamment d'étudier la décomposition des états propres entre la périphérie et le coeur du graphe. Pour ce faire, nous essayons actuellement de développer des observables pertinentes afin de caractériser la forme des états pour dépasser la mesure simple d'IPR. Par ailleurs, Ainsi, tous les résultats que nous avons présentés ici soulignent bien l'idée que la présence d'un désordre, même très faible, peut permettre d'améliorer la qualité du processus d'absorption au coeur du graphe en étoile d'étoiles
