Topology-induced phenomena and caloric effects in condensed matter
The first part of the thesis deals with the impact of surface-functionalized nanoparticles (NP) can have on the stability of liquid crystal (LC) phases. Experimental data of NP concentration-driven phase transition between the isotropic and nematic phase in 5OO8 LCs were used to create a minimal mathematical model that would …
Chirality and nanoparticles enforced stabilization of topological defects in liquid crystals
Of our main interest in this work is the stabilization of assemblies of topological defects (TDs) in liquid crystals (LCs). Due to the topological origin of TDs, the physics of defects is of interest for all branches of physics, including condensed matter systems, particle physics, and cosmology. LCs represent an …
Giant energy-conversion effects in soft and solid advanced materials
This thesis presents the results of our experimental work in the field of new advanced materials such as liquid crystal elastomers (LCEs), electrocalorics and magnetoelectrics. In the first part, the conversion of thermal to mechanical energy is addressed in LCEs. The three important, newly discovered, chemical and physical parameters for …
