The primary objective is to analyze the impact and evolution of the magma ocean and ... -
Crystals with magnetic frustration and multiferroic coupling
Výsledek obhajoby: OBHÁJENO(Univerzita Karlova, Matematicko-fyzikální fakulta, 2023)Datum obhajoby: 5. 9. 2023This thesis focuses on the growth of single crystals and magnetic characterization of CeMgAl11O19, a triangular lattice frustrated magnet from the rare earth hexaaluminate family. The CMAO harbors a network of electric ... -
Parameterized Approximations of Directed Steiner Networks
Výsledek obhajoby: OBHÁJENO(Univerzita Karlova, Matematicko-fyzikální fakulta, 2023)Datum obhajoby: 11. 9. 2023An instance of the Directed Steiner Network (DSN) problem consists of a directed graph G with edge costs, and k so called "terminal" vertex pairs. The task is to find a minimum-cost subgraph of G in which all terminal pairs ... -
