Coherent Light-Matter Interactions in Monolayer Transition-Metal Dichalcogenides

This thesis presents optical methods to split the energy levels of electronic valleys in transition-metal dichalcogenides (TMDs) by means of coherent light-matter interactions. In particular, by using off-resonance circularly polarized light at small detuning, one can tune the energy level of one valley through the optical Stark effect.

Aceasta teza prezinta metode optice pentru a imparti nivelurile de energie ale vailor electronice in dichalcogenide de tranzitie-metal (TMD) prin intermediul interactiunilor coerente lumina-materie. In special, prin utilizarea luminii polarizate circular in afara rezonantei la o detunare mica, se poate regla nivelul de energie al unei vai prin efectul Stark optic.
