Hi there! I am Tomáš Bzdušek, currently a professor leading the group Theory of Topological Matter at the University of Zürich, Switzerland. You can read more about my research in my profile. On these pages, which have until recently served as my personal website, I have collected the research work of myself and of my students. In the “miscellaneous” tab I have collected various further documents, including recorded talks, slides, and code. Note that this page is outdated, for current updates you should follow our group’s website.

Simulating hyperbolic space on a circuit board
Curved spaces are usually associated with high-energy physics and cosmology. However, through the possibility of tabletop experiments emulating curved spaces and the interest in related synthetic matter, they have become relevant in condensed matter physics as well.

Theorists discover new paradigm of topological band structures
After the experimental discovery of topological insulators, the notion of what actually constitutes a topological band insulator has been refined in many ways. In their recent work, Aleksandra Nelson, Titus Neupert, Tomáš Bzdušek and Aris Alexandradinata extend the paradigm of topological insulators to areas which were previously thought to contain only trivial insulators.

Non-Abelian topology reveals a relation between triple points and nodal links
Electron band structures, which describe the energy-momentum relation for electrons in solids, can exhibit robust crossings called "nodes". Such nodes famously occur in graphene or in Weyl semimetals, and often facilitate special transport phenomena, such as the decrease of resistivity of Weyl semimetals in applied parallel magnetic field.
