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.

Introduction to Computational Fluid Dynamics

Where we will discuss the Navier-Stokes equations and then break down the problem with the presence of solid objects implementing a simple real-time solver in Python.

Image Ranker: A Web App for Pairwise Image Ranking

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.

TERRA: The Tiny Terrain Generator

This Python package provides various physics simulations for hydraulic erosion, tectonic dynamics, weather patterns, biomes, geological primitives, tesselations, filters, and more to quickly generate highly realistic terrains.

Simulating & Animating Science with Python

A free collection of tutorials and simulation examples that aim to showcase and explain the animation capabilites one has using Python. This includes chemical reaction diffusion, the viral spread in pandemics, fractals, chaotic pendulums with springs, Conway’s game of life, quantum states of hydrogen, galaxy collisions, and much more.

Augmenting Obsidian.md with AI

A simple Python script to quickly organize your markdown notes in Obsidian.md using OpenAI’s large language models. Any random, untagged, empty, or unlinked notes? No more. This little script will fill the gaps, connect what belongs together, and even create high level organizing nodes if a specific topic has a lot of notes. It also provides additional meta-information and visualizations.

IC3D: Render .gds Files in 3D

.gds to .gltf file conversion and workflow to create photo-real animations of your photonic/electronic integrated circuits. Compared to other scripts, this one takes into account complex nested cell structures, rotations, and flips as one typically encounters them in photonic integrated circuits.
