The list below includes some recent side-projects I worked on in my free time.

Field-Dependent THz Transport Nonlinearities in Semiconductor Nano Structures
Quentin Wach, Michael T. Quick, Sabrine Ayari, Alexander W. Achtstein
The charge transport in semiconductor quantum dots and nanorods is studied theoretically, predicting strong field-dependent nonlinear mobility effects and intra-pulse gain. We studied the temperature- and size-sensitive mobility spectra, crucial for applications like 6G tech and nano electronics in general.

THz Response of Charge Carriers in Nanoparticles
Michael T. Quick, Quentin Wach, Nina Owschimikow, Alexander W. Achtstein
Presenting a new quantum mechanical theory that models the THz mobility of charge carriers in low-dimensional semiconductors, revealing nonlinearities even at low field-strengths as well as a quantum mechanical equilibration current that counteracts the mobility at low frequencies.

Image Ranker: The Web App for Fast Ranking of Large Image Collections
Training generative image models requires a way to compare images and provide feedback on which images are better. I built a web app to do just that using the TrueSkill algorithm for accurate and fast Bayesian ranking and various other features.

BEAMZ: Fast and Easy Electromagnetic Simulation and Inverse Design.
This Python package is built to support multiple backends (e.g. for GPU acceleration), features a high-level API that enables fast prototyping and design with just a few lines of code, includes live visualization of your 3D designs and real-time field propagation, while also providing its own FDTD and FDFD eigen-mode solvers.
