Description

The authors propose a scheme to excite the dark exciton ground state in a quantum dot, based on the use of a longitudinally polarized laser pulse to excite an energetically higher exciton state exhibiting a strong mixing of bright and dark spin configurations.

Translated Description (Arabic)

يقترح المؤلفون مخططًا لإثارة حالة أرضية إكسيتون المظلمة في نقطة كمية، بناءً على استخدام نبضة ليزر مستقطبة طوليًا لإثارة حالة إكسيتون أعلى بقوة تظهر خلطًا قويًا بين تكوينات الدوران الساطعة والمظلمة.

Translated Description (French)

Les auteurs proposent un schéma pour exciter l'état fondamental de l'exciton sombre dans un point quantique, basé sur l'utilisation d'une impulsion laser polarisée longitudinalement pour exciter un état exciton énergétiquement plus élevé présentant un fort mélange de configurations de spin clair et sombre.

Translated Description (Spanish)

Los autores proponen un esquema para excitar el estado fundamental del excitón oscuro en un punto cuántico, basado en el uso de un pulso láser polarizado longitudinalmente para excitar un estado de excitón energéticamente más alto que exhibe una fuerte mezcla de configuraciones de espín brillantes y oscuras.
