Quantum Harmonic Oscillator Sonification [PDF]

, 2010
This work deals with the sonification of a quantum mechanical system and the processes that occur as a result of its quantum mechanical nature and interactions with other systems. The quantum harmonic oscillator is not only regarded as a system with sonifiable characteristics but also as a storage medium for quantum information.

Integrated Optoelectronic Model to Predict the External Quantum Efficiency of Single‐Layer TADF Organic Light‐Emitting Diodes

Advanced Electronic Materials, EarlyView.
An experimentally validated optoelectronic device model is presented to describe the efficiency and roll‐off behavior of single‐layer TADF OLEDs. By coupling charge transport, exciton dynamics, and optical outcoupling, the model reproduces the External Quantum Efficiency (EQE) across different emission layer thicknesses and temperatures, offering ...
