Charged excitons in monolayer WSe 2 : Experiment and theory
© 2017 American Physical Society. Charged excitons, or X± trions, in monolayer transition-metal dichalcogenides have binding energies of several tens of meV. Together with the neutral exciton X0 theyExpand

Cancerous Cell Death from Sensitizer Free Photoactivation of Singlet Oxygen
Singlet oxygen (1O2) is an electronic state of molecular oxygen which plays a major role in many chemical and biological photo‐oxidation processes. It has a high chemical reactivity which is commonlyExpand

A minimal titration model of the mammalian dynamical heat shock response.
Environmental stress, such as oxidative or heat stress, induces the activation of the heat shock response (HSR) and leads to an increase in the heat shock proteins (HSPs) level. These HSPs act asExpand

Kinetics of helium 3 laser optical pumping
We report on optical pumping experiments in helium-3 using a new broad-band, all fiber laser at 1083 nm. The kinetics of polarization build-up are compared to the numerical results of an appropriateExpand

Fine structure and lifetime of dark excitons in transition metal dichalcogenide monolayers
The intricate interplay between optically dark and bright excitons governs the light-matter interaction in transition metal dichalcogenide monolayers. We have performed a detailed investigation ofExpand

Interlayer excitons in bilayer MoS 2 with strong oscillator strength up to room temperature
Coulomb bound electron-hole pairs, excitons, govern the optical properties of semiconducting transition-metal dichalcogenides like MoS 2 and WSe 2. We study optical transitions at the K point for 2HExpand

A high-power tunable Raman fiber ring laser for the investigation of singlet oxygen production from direct laser excitation around 1270 nm.
We report on the development of a tunable Raman fiber ring laser especially designed for the investigation of the 3Σ(-)(g) →1 Δg transition of molecular oxygen. Singlet oxygen (1Δg) is a reactiveExpand
