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…
Nonclassical Exciton Diffusion in Monolayer WSe2
Koloman Wagner, Jonas Zipfel, Roberto Rosati +9
We experimentally demonstrate time-resolved exciton propagation in a monolayer semiconductor at cryogenic temperatures. Monitoring phonon-assisted recombination of dark states, we…
Non-equilibrium diffusion of dark excitons in atomically thin semiconductors
Roberto Rosati, Koloman Wagner, Samuel Brem +7
Atomically thin semiconductors provide an excellent platform to study intriguing many-particle physics of tightly-bound excitons. In particular, the properties of tungsten-based tr…
The Multi-Field, Rapid-Turn Inflationary Solution
Vikas Aragam, Sonia Paban, Robert Rosati
There are well-known criteria on the potential and field-space geometry for determining if slow-roll, slow-turn, multi-field inflation is possible. However, even though it has been…
Strain-dependent exciton diffusion in transition metal dichalcogenides
Roberto Rosati, Samuel Brem, Raül Perea-Causín +5
Monolayers of transition metal dichalcogenides (TMDs) have a remarkable excitonic landscape with deeply bound bright and dark exciton states. Their properties are strongly affected…
Temporal evolution of low-temperature phonon sidebands in WSe monolayers
Roberto Rosati, Samuel Brem, Raül Perea-Causín +9
Low-temperature photoluminescence (PL) of hBN-encapsulated monolayer tungsten diselenide (WSe) shows a multitude of sharp emission peaks below the bright exciton. Some of them…
