Coulomb-mediated interactions of charge-transfer excitons in TMD lateral heterostructures
Kabyashree Sonowal, Daniel Erkensten, Ermin Malic +1
Lateral heterostructures of transition-metal dichalcogenides (TMDs) host spatially separated charge-transfer (CT) excitons. While analogous to interlayer excitons in vertical TMD h…
Valley-controlled many-body exciton interactions in monolayer WSe phototransistors
Daniel Vaquero, Cédric A. Cordero-Silis, Daniel Erkensten +6
Many-body exciton interactions shape the optoelectronic response of atomically-thin transition metal dichalcogenides, yet optical control of these interactions remains largely unex…
Exciton Polariton-Polariton Interactions in Transition-Metal Dichalcogenides
Jonas K König, Jamie M Fitzgerald, Daniel Erkensten +1
Microscopic insights into nonlinear interactions are essential for advancing polaritonic devices. Existing studies often rely on phenomenological models that overlook important man…
Impact of an electron Wigner crystal on exciton propagation
Daniel Erkensten, Alexey Chernikov, Ermin Malic
The strong Coulomb interaction in 2D materials facilitates the formation of tightly bound excitons and charge-ordered phases of matter. A prominent example is the formation of a cr…
Electrically tunable ultrafast dynamics and interactions of hybrid excitons in a 2D semiconductor bilayer
Edoardo Lopriore, Charalambos Louca, Armando Genco +12
Extended efforts have been devoted to the study of strongly-interacting excitons and their dynamics, towards macroscopic quantum states of matter such as Bose-Einstein condensates…
