Project C01: Measurement and manipulation of topological excitations This project explores the influence of measurement processes on entangled states of matter. This platform is quite advanced experimentally and has already allowed to establish the existence of Majorana bound states. Project A02 Gapless topological matter considers the more recent extensions of the topology paradigm to the strongly spin-orbit entangled gapless Weyl metal and semimetal phases. Project B03: Theory of fractionalized topological phases While noninteracting topological phases are by now well understood, we are only on the verge of understanding the wealth of fractionalized topological phases, in which interactions stabilize novel types of long-range entanglement. We will propose new Majorana-based quantum computation schemes as well as meta-materials based on entangled large spins. Alessio Chiocchetta postdoctoral researcher Room: 3. Relevant statistics qualify cardiovascular disease as the leading cause of death in 40 % of cases.

NextThe emphasis of this research is the targeted use of suitably tailored dissipative processes to prepare topologically non-trivial states in a robust manner. Quantum superpositions, however, are highly vulnerable to environmental perturbations such as radiation, noise, or other sources of quantum wave decoherence — the main reason why such type of quantum information processing has not become a reality yet. A salient feature of entangled quantum matter is that the large number of atomistic constituents forming a solid may mutually protect each other against the detrimental effects of decoherence. Project A03: Disordered topological matter Project A03 focuses on the surprisingly rich interplay of topological order with the static disorder inevitably present in any realistic condensed matter system. We will advance platforms for universal topological quantum computation exploiting the proximity coupling of superconductors and quantum Hall systems.

NextIt also contains a more fundamental line of activity, aiming at the construction of a mathematically rigorous classification of non-translationally invariant topological matter. Dissipative processes result from the interaction of a system's degrees of freedom with their environment. However, if properly designed, they need not counteract mechanical correlations, but can even create them. We seek analytic, numerical, and experimental methods for quantifying entanglement in fermionic and bosonic many-body systems. In this way, important applications for quantum information, such as the creation of quantum memories, will be enabled. Tensor networks feature strongly as a tool to capture the intricate correlations in states of quantum many-body systems and in the classification of phases in two dimensions. This will include periodic modulations for which novel phases of topological matter can emerge.

NextAnother branch of the project explores how topological excitations forming at the interfaces between distinct topological phases — the most elementary states utilized by quantum information protocols — respond to dynamical processes involved in any braiding protocol. After these concepts have been implemented for the comparatively basic case of Majorana bound states, we will turn towards more complex parafermion excitations. Project A01: Topology and dynamics The project investigates how topological states and excitations can be created and manipulated in environments with externally imposed time dependence.

NextIn the industrialised countries of the western world cerebrovascular insufficiency is the third most common disease affecting the general population following cardiac disease and cancer. We are studying molecular responses of plants to the light environment, in particular the role of protein degradation in light-controlled plant development.

In a symbiosis with experimental efforts of the Marcus group, we will propose and study further signatures of Majorana bound states, explore schemes to benchmark, control, and read out an elementary topological qubit, and develop strategies for implementing Majorana braiding operations. Project A02: Gapless topological phases Initially, research on topological matter focused on gapped phases, such as topological insulators or superconductors. The focus of project B03 is to explore experimentally feasible manifestations of such phases and in particular to search for fractionalized quasiparticles whose non-abelian exchange statistics goes beyond those of Majorana fermions.

NextWe will study entanglement between a single block and attached leads, as well as entanglement generated in assemblies of blocks all the way to two-dimensional lattices thereof. .

Project B02: Topology, dissipation, and quantum memories The goal of this project is the investigation of the subtle interplay between dissipation and topology. This project aims at broadening both the materials base for engineering such phases and the classes of accessible topological phases. The project explores the integrity of the topological phases of insulators and metals, including topological phases protected by discrete symmetries that are broken by the disorder.
