Topological band theory of relativistic spintronics in antiferromagnets
Šmejkal, Libor ; Jungwirth, Tomáš (advisor) ; Kuneš, Jan (referee) ; Shick, Alexander (referee)
Nanoelectronics and spintronics are concerned with writing, transporting, and reading information stored in electronic charge and spin degrees of freedom at the nanoscale. Past few years have shown that two spintronics effects discovered in the 19th century, namely anisotropic magnetoresistance and anomalous Hall effect, can be used also for sensing antiferromagnetism which opened the field of antiferromagnetic spintronics. The more than a century of controversial studies of these effects have shown their relativistic spin-orbit coupling and spin-polarisation symmetry breaking origin. However, a complete understanding of these effects and a fully predictive theory capable of identifying novel suitable antiferromagnetic materials are still lacking. Here, by extending modern symmetry and topology concepts in condensed matter physics, we have further developed the theory of anisotropic magnetoresistance and spontaneous Hall effect. Our approach is based on magnetic symmetry and topology analysis of antiferromagnetic energy bands, Bloch spectral functions, and Berry curvatures calculated from the state-of-the- art first-principle theory. This guided us to the prediction of two novel, previously unanticipated effects: relativistic metal-insulator transition from antiferromagnetic Dirac fermions, and crystal Hall...
The Ground of the World: A Marginal Problem in Hegel's Phenomenology of Spirit
Matějčková, Tereza ; Karásek, Jindřich (advisor) ; Gutschmidt, Holger (referee) ; Kuneš, Jan (referee)
Is there a world in G. W. F. Hegel's The Phenomenology of Spirit? This is the central question my doctoral thesis aims to address. Both scholars and philosophers alike tend to consider Hegel a thinker who, having formulated the philosophy of absolute spirit, has surrendered the world. Despite this suspicion, the consciousness finds itself at nearly every level of Hegel's oeuvre in a place called "the world". At every stage, the world changes its shape - along with the consciousness - but its function seems to remain the same. The world is a conception of totality; thus, the world is an object of the consciousness that, by definition, surpasses the consciousness and thus reveals its limits. This moment of a "worldly" estrangement is especially pronounced as the consciousness sets itself into action. One of the most recurring motives in Hegel's The Phenomenology of Spirit is the inability of the consciousness to realize its intentions as planned. The consciousness fails to recognize itself in the deed, and thus devises strategies to distance itself from the deed. In my interpretation, this testifies that the deed is the door to the world, and obviously this world is not one that would be in the power of the consciousness. Instead, it is the consciousness that needs to subordinate itself to the deed...
The Problem of Self-consciousness in Fichte's Philosophy. Study in Pragmatic History of the Human Mind
Vrabec, Martin ; Karásek, Jindřich (advisor) ; Sobotka, Milan (referee) ; Kuneš, Jan (referee)
Submitted essay is an inquiry into J. G. Fichte's early philosophy focused particularly on Foundation of the Entire Wissenschaftslehre as a central work of his early period. Interpretation is based on assumption that its principal aim consists in manifestation of the way leading to emergence of our commonsense and ordinary understanding with reference to both world and ourselves. This approach carries Fichte's affilation with tendency inherent to transcendental philosophy of his era not only in its search for the origin of empirical knowledge, but for the origin of aprioristic structures of our experience especially. His transcendentally laden search manifests itself as so called "pragmatic history of the human mind", the principal object of our inquiry. Here we can find an attempt to reconstruct just transcendental, but not "real", temporally sequential, genesis of our mind from original state of feeling to our common representation both about independently existing things and ourselves as free cognizing subjects. Application of this philosophical method allows him to genetically derive and justify basic forms of our experience and its aprioristic components like space, time, substantiality or causality. The first part of essay introduces fundamental principles of Fichte's philosophical system and...
Investigation of markers for the diagnostics of metabolic syndrome
KUNEŠ, Jan
In my Bachelor´s thesis I dealt with the issue of investigation of biochemical markers, which are used for diagnostics of metabolic syndrome along with measurement of waist circumference and level of blood pressure. In the theoretical part I defined the term metabolic syndrome. Chapters about glucose and blood lipids tests as well as methods used for their determination are described in detail. Great attention was also paid to preanalytical factors, which significantly share of the accuracy of laboratory test. Practical part of the Bachelor´s thesis is focused on acquisition of practical skills in work with biological material in the laboratory of clinical biochemistry and acquisition of principals of laboratory methods. Under professional supervision in the biochemical laboratory Laboma s.r.o. in České Budějovice, I tested 100 samples of venous blood, where I determined concentration of fasting glucose, triglycerides and HDL cholesterol. The measurement was carried out on the biochemical analyzer Cobas Integra 800 by the method of absorption spectrophotometry. Measured laboratory values were statistically processed and they were interpreted after consultation with the supervisor of the Bachelor´s thesis. The laboratory tests showed that the criteria of metabolic syndrome applied for 21% of women and 15% of men.
