Abstrakt
This talk is intended as a broad overview of graphical causal inference, including causal discovery, where the task is to learn a causal graph, and causal e?ect estimation, where a causal graph is already assumed and the task is to quantify causal e?ects. In both cases a focus will be on statistically robust estimation strategies, including a theoretical optimality result for adjustment-based causal eect estimation. I will also illustrate practical work?ows in my software package Tigramite.

Abstrakt
Many applications require diode lasers that are able to generate high output powers, for example in LiDAR (Light Detection and Ranging) systems or in future inertial confinement fusion power plants. In order to achieve high powers while maintaining low injected current densities, it is beneficial to stack multiple active regions and separate them using tunnel junctions. As the tunnel junctions are highly absorbing due to the small band gap and high doping levels, their accurate positioning in the nodes of the vertical mode is crucial. In order to answer important design questions such as the optimal distance between active regions and the tunnel junctions, a simulation tool is required. For our tool we solve the standard drift-diffusion equations augmented with additional models to describe effects such as tunneling and stimulated emission. Since the tunnel junctions are operated under reverse bias, we employ a non-local band-to-band tunneling model. This talk presents the simulation model and demonstrates its application to a multi-junction laser diode.

A Navier--Stokes/Mullins--Sekerka system with different densities: Weak solutions

Abstrakt
In this talk, I would like to introduce a model for the flow of two incompressible, viscous and immiscible fluids in a bounded domain, with different densities and viscosities. This model consists of a coupled system of Navier--Stokes and Mullins--Sekerka type parts, and can be obtained from the asymptotic limit of the diffuse interface model introduced by Abels, Garcke, and Grün in 2012. I will introduce a new notion of weak solutions and prove its global in time existence, together with a consistency result. This new notion of solution allows to include the case of different densities of the fluids, a sharp energy dissipation principle `a la De Giorgi, as well as a weak formulation of the constant contact angle condition at the boundary, which were left open in the previous notion of solution proposed by H. Abels and M. Röger in 2009. This is a joint project with H. Abels.
