Electron dynamics in a 2D nanobubble: A two-level system based on spatial density
Roberto Rosati, Frank Lengers, Christian Carmesin +5
Nanobubbles formed in monolayers of transition metal dichalcogenides (TMDCs) on top of a substrate feature localized potentials, in which electrons can be captured. We show that th…
High-gain quantum free-electron laser: long-time dynamics and requirements
Peter Kling, Enno Giese, C. Moritz Carmesin +2
We solve the long-time dynamics of a high-gain free-electron laser in the quantum regime. In this regime each electron emits at most one photon on average, independently of the ini…
Imaging strain-localized exciton states in nanoscale bubbles in monolayer WSe2 at room temperature
Thomas P. Darlington, Christian Carmesin, Matthias Florian +14
In monolayer transition metal dichalcogenides, quantum emitters are associated with localized strain that can be deterministically applied to create designer nano-arrays of single…
Quantum and classical phase-space dynamics of a free-electron laser
C. Moritz Carmesin, Peter Kling, Enno Giese +2
In a quantum mechanical description of the free-electron laser (FEL) the electrons jump on discrete momentum ladders, while they follow continuous trajectories according to the cla…
A high-gain Quantum free-electron laser: emergence & exponential gain
Peter Kling, Enno Giese, C. Moritz Carmesin +2
We derive an effective Dicke model in momentum space to describe collective effects in the quantum regime of a free-electron laser (FEL). The resulting exponential gain from a sing…
Quantum-dot-like states in molybdenum disulfide nanostructures due to the interplay of local surface wrinkling, strain, and dielectric confinement
Christian Carmesin, Michael Lorke, Matthias Florian +4
The observation of quantum light emission from atomically thin transition metal dichalcogenides has opened a new field of applications for these material systems. The corresponding…
