Triplet Exciton Management via Solid-State Interactions in Organic Semiconductors
… This thesis investigates the effects of solid-state interactions on triplet excitons in a new family of organometallic light emitters, carbene-metal-amides (CMAs). Triplet excitons are normally silent in luminescence due to the spin-forbidden decay process, whereas effectively harvesting …

Measurement of Pion-Pion Final State Interactions in η → π +π −γ with CLAS at Jefferson Lab
… frameworks have been proposed to describe these interactions. We report a new measurement of the α parameter which measures the contribution of pion-pion final state interactions to the differential decay width.</p> <p>The data was collected during the g11a run period using the CEBAF Large …

Nucleon-Nucleon Spin Dependent Scattering Amplitudes to Describe Final State Interactions in Electromagnetic and Electroweak Nuclear Processes
… an application of the model to describe final state interactions in deuteron electrodisintegration is presented. Overall the model works as intended, and provides an adequate description of the nucleon-nucleon interaction at these energies.</p>

Electro-Pionproduction from P, D, and 3He
… For the d( e, e'rr+)2n reaction, final state interactions between the two outgoing neutrons are found to have a large effect. The calculated quenching of the rr+ production cross section for the deuterium target is in agreement with that observed experimentally. It is predicted that due …

Measurement of nuclear transparency from A(e,e'[pi]⁺) reactions
… phenomenon refers to the suppression of final-state interactions of a hadron propagating through the nuclear medium at large momentum transfer when the hadron is produced with small transverse size. The pion electroproduction cross section from 1H, 2H,12C, 63Cu and 197Au targets from Q2 = 1.1 …

THE PION DOUBLE DIFFERENTIAL CHARGE EXCHANGE CROSS SECTION IN PROTODUNE-SP
… > 1$GeV neutrino beam. Higher energy neutrino interactions are more complicated and produce more charged pions with sizable effects from final state interactions as they traverse the nucleus. The final state interactions, especially of charged pions, can lead to mis-identification of neutrino …

Quenching normal Bose gases to Unitarity
The presence of inter-particle interactions in a system elevates the physics involved from fundamentally single-body, with each particle following its own trajectory according to external forces, to many-body, with collective behaviour emerging from the interplay between the multitude of particles. …

Antimicrobial Resistance Mediated By Synthesis of Richmond and Sykes Type I Beta-Lactamase
… frequency of mutation to a stably derepressed state. Interactions between these bacterial strains and beta-lactam drugs were examined through growth curves. A rapid susceptibility test was evaluated for detection of this resistance. These results emphasize the need to carefully evaluate …

Twist angle physics in graphene based van der Waals heterostructures
… limit, the two sheets have little interlayer interactions and are strongly decoupled, allowing us to put independent quantum Hall edge modes in both layers. We study the edge state interactions in this system, culminating in the formation of a quantum spin Hall state in twisted bilayer …

Interaction of germanium with platinum group metals in lateral diffusion couples
… could extend to lengths of around 100 µm. Solid-state interactions in both thin-film and bulk diffusion couples can therefore be investigated using lateral diffusion couples. In particular the transition between the two types of interactions can be studied.
