In the 60 years since the invention of the laser, the scientific community has developed
numerous fields of research based on these bright, coherent light sources, including the …

Nanoscale systems are forecast to be a means of integrating desirable attributes of
molecular and bulk regimes into easily processed materials. Notable examples include …

Monolayer MoS2 is a direct-gap two-dimensional semiconductor that exhibits strong
electron–hole interactions, leading to the formation of stable excitons and trions. Here we …

Quantum mechanics provides the most accurate microscopic description of the world around
us, yet the interface between quantum mechanics and biology is only now being explored …

We studied multiexciton dynamics in monolayer WSe 2 using nonlinear photoluminescence
(PL) spectroscopy and Monte Carlo simulations. We observed strong nonlinear saturation …

Graphene nanoribbons display extraordinary optical properties due to one-dimensional
quantum-confinement, such as width-dependent bandgap and strong electron–hole …

An overall understanding of the carrier dynamics in two-dimensional transition metal
dichalcogenides (TMDs) is necessary to improve the quantum efficiencies and …

Unraveling the nature of energy transport in multi-chromophoric photosynthetic complexes is
essential to extract valuable design blueprints for light-harvesting applications. Long-range …

We investigate exciton dynamics in isopycnically enriched (6, 5) nanotube-DNA
suspensions using femtosecond time-resolved pump− probe spectroscopy. The ground …

Time-resolved spectroscopy is commonly used to study diverse phenomena in chemistry,
biology, and physics. Pump–probe experiments and coherent two-dimensional (2D) …
