Ontologies for Models and Algorithms in Applied Mathematics and Related Disciplines
Björn Schembera, Frank Wübbeling, Hendrik Kleikamp +8
In applied mathematics and related disciplines, the modeling-simulation-optimization workflow is a prominent scheme, with mathematical models and numerical algorithms playing a cru…
Research-Data Management Planning in the German Mathematical Community
Tobias Boege, René Fritze, Christiane Görgen +13
In this paper we discuss the notion of research data for the field of mathematics and report on the status quo of research-data management and planning. A number of decentralized a…
Impact of random alloy fluctuations on the carrier distribution in multi-color (In,Ga)N/GaN quantum well systems
Michael O'Donovan, Patricio Farrell, Julien Moatti +3
In this work, we study the impact that random alloy fluctuations have on the distribution of electrons and holes across the active region of a (In,Ga)N/GaN multi-quantum well based…
Symmetries in TEM imaging of crystals with strain
Thomas Koprucki, Anieza Maltsi, Alexander Mielke
TEM images of strained crystals often exhibit symmetries, the source of which is not always clear. To understand these symmetries we distinguish between symmetries that occur from…
Multiscale simulations of uni-polar hole transport in (In,Ga)N quantum well systems
Michael O'Donovan, Patricio Farrell, Timo Streckenbach +2
Understanding the impact of the alloy micro-structure on carrier transport becomes important when designing III-nitride-based LED structures. In this work, we study the impact of a…
On the Darwin-Howie-Whelan equations for the scattering of fast electrons described by the Schrödinger equation
Thomas Koprucki, Anieza Maltsi, Alexander Mielke
The Darwin-Howie-Whelan equations are commonly used to describe and simulate the scattering of fast electrons in transmission electron microscopy. They are a system of infinitely m…
Beyond just "flattening the curve": Optimal control of epidemics with purely non-pharmaceutical interventions
Markus Kantner, Thomas Koprucki
When effective medical treatment and vaccination are not available, non-pharmaceutical interventions such as social distancing, home quarantine and far-reaching shutdown of public…
Non-isothermal Scharfetter-Gummel scheme for electro-thermal transport simulation in degenerate semiconductors
Markus Kantner, Thomas Koprucki
Electro-thermal transport phenomena in semiconductors are described by the non-isothermal drift-diffusion system. The equations take a remarkably simple form when assuming the Kelv…
Hybrid quantum-classical modeling of quantum dot devices
Markus Kantner, Markus Mittnenzweig, Thomas Koprucki
The design of electrically driven quantum dot devices for quantum optical applications asks for modeling approaches combining classical device physics with quantum mechanics. We co…
