Impact of exciton-phonon and exciton-magnon interaction on transport in anisotropic 2D magnetic semiconductors
Daniel Erkensten, Katarzyna Sadecka, Marie-Christin Heißenbüttel +2
Two-dimensional magnetic semiconductors provide a unique platform for exploring the interplay between charge, lattice, spin, and light. The strong Coulomb interaction combined with…
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…
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…
Electrically tunable dipolar interactions between layer-hybridized excitons
Daniel Erkensten, Samuel Brem, Raul Perea-Causin +5
Transition-metal dichalcogenide bilayers exhibit a rich exciton landscape including layer-hybridized excitons, i.e. excitons which are of partly intra- and interlayer nature. In th…
Electrical control of hybrid exciton transport in a van der Waals heterostructure
Fedele Tagarelli, Edoardo Lopriore, Daniel Erkensten +9
Interactions between out-of-plane dipoles in bosonic gases enable the long-range propagation of excitons. The lack of direct control over collective dipolar properties has hitherto…
Interlayer exciton polaritons in homobilayers of transition metal dichalcogenides
Jonas K. König, Jamie M. Fitzgerald, Joakim Hagel +2
Transition metal dichalcogenides integrated within a high-quality microcavity support well-defined exciton polaritons. While the role of intralayer excitons in 2D polaritonics is w…
Exciton optics, dynamics and transport in atomically thin semiconductors
Raul Perea-Causin, Daniel Erkensten, Jamie M. Fitzgerald +4
Atomically thin semiconductors such as transition metal dichalcogenide (TMD) monolayers exhibit a very strong Coulomb interaction, giving rise to a rich exciton landscape. This mak…
Microscopic origin of anomalous interlayer exciton transport in van der Waals heterostructures
Daniel Erkensten, Samuel Brem, Raül Perea-Causin +1
Van der Waals heterostructures constitute a platform for investigating intriguing many-body quantum phenomena. In particular, transition-metal dichalcogenide (TMD) hetero-bilayers…
Dark exciton-exciton annihilation in monolayer WSe
Daniel Erkensten, Samuel Brem, Koloman Wagner +8
The exceptionally strong Coulomb interaction in semiconducting transition-metal dichalcogenides (TMDs) gives rise to a rich exciton landscape consisting of bright and dark exciton…
Topology of critical chiral phases: multiband insulators and superconductors
Oleksandr Balabanov, Daniel Erkensten, Henrik Johannesson
Recent works have proved the existence of symmetry-protected edge states in certain one-dimensional topological band insulators and superconductors at the gap-closing points which…
