(Slow-)Twisting inflationary attractors
Perseas Christodoulidis, Robert Rosati
We explore in detail the dynamics of multi-field inflationary models. We first revisit the two-field case and rederive the coordinate independent expression for the attractor solut…
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…
Signatures of dark excitons in exciton-polariton optics of transition metal dichalcogenides
Beatriz Ferreira, Roberto Rosati, Jamie M. Fitzgerald +1
Integrating 2D materials into high-quality optical microcavities opens the door to fascinating many-particle phenomena including the formation of exciton-polaritons. These are hybr…
Microscopic modelling of exciton-polariton diffusion coefficients in atomically thin semiconductors
Beatriz Ferreira, Roberto Rosati, Ermin Malic
In the strong light-matter coupling regime realized e.g. by integrating semiconductors into optical microcavities, polaritons as new hybrid light-matter quasi-particles are formed.…
