    The study of non-equilibrium dynamics of magnetic degrees of freedom has shown remarkable progress over the past two decades. This is in particular true concerning the understanding of ultrafast magnetization dynamics in classical magnets. In contrast, the field of non-equilibrium spin dynamics of many-body quantum magnetic systems is still in its infancy. Despite a number of ground-breaking recent theoretical proposals, experimental studies in this direction are truly scarce and this research field is a largely unexplored territory. Here I propose to study non-equilibrium dynamics in a number of well-selected quantum spin systems, utilizing a novel and powerful experimental technique – time-resolved terahertz spectroscopy under extreme conditions. By carrying out the here proposed program of non-equilibrium and nonlinear studies on low-dimensional and/or frustrated quantum magnets, I aim to explore and reveal novel physics and the governing fundamental principles for the non-equilibrium quantum spin dynamics. Firstly, I aim to realize novel quantum phenomena and quantum effects, which are difficult to be detected in the equilibrium state, such as complex many-body bound states. Secondly, I will explore novel characteristics for exotic quantum states like quantum spin liquids and quantum critical phases in the nonlinear response regime, by driving the quantum disordered states far from equilibrium. Thirdly, I aim to tune and control the non-equilibrium and nonlinear response of the quantum spin states either by the terahertz electromagnetic fields directly or via coupling to other degrees of freedom, such as phonons. Gaining momentum from the on-going intensive theoretical studies and based on my previous work in the field of quantum spin systems, I anticipate a productive, impactful, and successful research project exploring the new physics offered by non-equilibrium quantum spin systems.

    In CC-CHARGED, I propose a new concept to induce C–C bond polarization as well as predict fundamentally new stable carbon-based compound classes. The manipulation of functional groups builds the basis for the rational design of complex molecules in organic synthesis. While most compound classes have been studied for decades, few remain virtually unexplored, only suggested as reactive intermediates. I propose to tame these elusive intermediates into hitherto unknown room-temperature stable compound classes. Central motif to gain stability relies in the polarization of the C–C bond, which can either result in zwitterions (charged +/-) or diradicals. The dichotomic behavior will be analyzed and a general approach to C–C bond polarization will be developed based on a new concept of mesoionic frustration. Such mesoions are predicted to be exceptionally strong polarized carbon compounds, exceeding the polarization of traditional ylides, triggering applications from transition metal, main group chemistry to organic synthesis. The reactivity of such strong carbon donors will be analyzed, correlated and a scale generated. Applications of C–C bond polarization in the stabilization of unsaturated diazo and monosubstituted carbon compounds are presented. Their synthesis, electronic structure and reactivity will be evaluated and applications such as C-atom transfer reagents for molecular editing studied. While singlet vinylidenes are central intermediates in organic reactions, the generation and reactivity of triplet vinylidenes is virtually unknown. I propose them as new compounds in organic chemistry, as metal-vinylidene precursors and as new platforms for magnetic applications. Recent high-impact publications by the group build the basis for this project that goes far beyond the state-of-the-art. Considering that carbon is the pivotal element of life and the central element of organic chemistry, CC-CHARGED is a fundamental, ground-breaking contribution to organic chemistry.

    The Standard Model of particle physics successfully describes all known particles and their interactions. However, questions like the nature of dark matter or the hierarchy of masses and couplings of quarks and leptons remain to be understood. Hence, one searches for new phenomena that will lead to a superior theory that can explain these questions. All such theories introduce additional quantum corrections. Decay rates of processes which are strongly suppressed in the Standard Model are highly sensitive to these corrections. The LHCb experiment at CERN has recorded the world’s largest sample of beauty mesons. In the five years of this proposal, this sample will be enlarged by more than a factor of five. This sets an optimal environment for precision tests for new phenomena in strongly suppressed beauty decays. This proposal aims to discover new scalar or vector particles in precision measurements of leptonic and semi-leptonic beauty decays. These new particles are not predicted by the Standard Model of particle physics, a potential discovery would mark the most important finding in High Energy Physics of the last decades. Some existing anomalies in flavour data can be interpreted as hints for the particles searched for in this proposal. Two classes of measurements are planned within this proposal: the complete scan of purely leptonic beauty decays which include flavour changing neutral current as well as lepton flavour violating modes. Lepton flavour universality is tested in loop decays through a novel inclusive strategy. All proposed measurements will advance the world’s knowledge significantly and have a large discovery potential.

    In mammalian genomes, epigenetic modifications of the nucleobase cytosine occur in both strands of the DNA duplex in the sequence “CpG”, and they are central regulators of gene expression as well as important cancer biomarkers. However, current analytical techniques cannot reveal the combination in that these modifications occur in the two strands of a DNA duplex. The resulting inability to create genomic maps of these “CpG duplex modifcations” represents a major roadblock for future developments in epigenetics research and cancer diagnosis. We have engineered the first affinity enrichment probes for selectively analysing novel CpG duplex modifications, and integrated them into user-friendly and cost-effective kits for genomic mapping. In this project, we will develop and commercialize two kits for mapping of the most important novel CpG duplex modification consisting of 5-methylcytosine and 5-hydroxymethylcytosine for the epigenetics research and the liquid biopsy markets. This will provide decisive new impulses for epigenetics research as well as for cancer biomarker discovery and liquid biopsy, both large and rapidly growing markets.

    Cyber-physical real-time systems are information processing systems that require both functional as well as timing correctness and have interactions with the physical world. Since time naturally progresses in the physical world, safe bounds of deterministic or probabilistic timing properties are required. PropRT will explore the possibilities to construct timing analysis for complex cyber-physical real-time systems from formal properties. The target properties should be modular so that safe and tight analysis as well as optimization can be performed (semi-)automatically. New, mathematical, modulable, and fundamental properties for property-based (schedulability) timing analyses and scheduling optimizations are needed to capture the pivotal properties of cyber-physical real-time systems, and thus enable mathematical and algorithmic research on the topic. Different flexibility and tradeoff options to achieve real-time guarantees should be provided in a modularized manner to enable tradeoffs between execution efficiency and timing predictability. The success of this project will provide a comprehensive view of the landscape of design, analysis, and optimization options for timing properties in cyber-physical real-time systems. Advanced optimization and analytical frameworks based on the formal properties of scheduling algorithms and schedulability analysis will serve as new ingredients for designing predictable cyber-physical systems, which will trigger a revolution of computer architectures, system modeling, communication mechanisms, and synchronization designs in the near future. The results will bring a new design process to further allow control designers and system integrators in cyber-physical real-time systems to jointly explore different configurations of controllers, computation, and communication parameters for designing timing predictable cyber-physical system applications.
