A Measure-Theoretic Perspective on Multivariate Information with Applications to Data Science
(2025-09-17)This dissertation establishes a measure-theoretic foundation for information theory by formulating entropy, mutual information, and related quantities on a common type of probability spaces. Using Radon–Nikodym derivatives ... -
Radial velocity search for extrasolar planets around late M dwarfs
(2025-08-29)The radial velocity (RV) method has revealed the presence of rocky exoplanets in the habitable zones of M dwarf stars in the Solar neighborhood. Some of the potentially most Earth-like exoplanets have been found orbiting ... -
Stellar variability of M stars in the context of exoplanet detection and characterisation
(2025-08-29)The detection and characterisation of exoplanets around M dwarfs is an important aspect in the search for low-mass planets outside our Solar System. M dwarfs are excellent targets for radial velocity (RV) detection due to ... -
Ultrafast exciton dynamics in moiré heterostructures
(2025-08-05)The optoelectronic properties of two-dimensional semiconductors are defined by two-particle correlated exciton states formed via the Coulomb interaction between single-particle holes and electrons. After excitation with ... -
Electrical Control and Spatial Visualization of Charge Density Waves in 1T-TaS2
(2025-07-31)Charge density waves (CDWs) are stable phases in crystalline materials, creating a peri- odic reordering of the electron density and thereby induce a distortion of the underlying atomic lattice. Such structural changes ... -
Constraining the Properties of Multiple Populations in Globular Clusters
(2025-07-31)Classically, all stars in a globular cluster are assumed to be very similar in age and chemical composition because they are thought to originate from the same giant molecular cloud. In recent years, researchers have ... -
