When they are combined, individual building blocks can produce completely new properties. The Complex Matter strategic research field was established to investigate and exploit these properties. It brings together some 27 professors from the Faculties of Physics and Earth Sciences, Chemistry and Mineralogy, Life Sciences, Mathematics and Computer Science, and the Faculty of Medicine. From their respective standpoints, they investigate the elementary properties of individual objects – from tiny ions and molecules to complex nanostructures. In this way, they can develop functional units from complex matter such as sensors, catalytic converters and electronic components. One example of where the work of researchers from physics and chemistry overlaps with the biosciences is in the field of cell mechanics, where scientists are investigating how and why a cell changes due to disease.

The Complex Matter research profile area combines excellent basic research with fascinating applications. The researchers are grappling with major challenges that can only be overcome through cooperation between disciplines hitherto regarded as independent, and by closely aligning the experimental with the theoretical.

Currently, approximately 50 doctoral candidates receive excellent, structured postgraduate training at the Graduate School Building with Molecules and Nano-objects (BuildMoNa), which forms part of the research profile area.

Polymers under Multiple Constraints (Transregio/CRC 102)
Transregio 102, “Polymers under Multiple Constraints”, is a long-term basic research project in an alliance with the Martin Luther University Halle-Wittenberg, drawing on expertise in chemistry, experimental and theoretical physics, and biophysics. Since 2011, the participating researchers have been investigating processes of structure formation and self-assembly in polymer systems, in which, apart from connectivity, molecular structure and dynamics are strongly influenced by additional constraints. Examples of such additional constraints are specific internal interactions, external forces, geometric constraints, high concentrations and topological interactions.

Integrated Chemical Micro Laboratories (InCheM) (FOR 2177)

The Integrated Chemical Micro Laboratories (InCheM) Research Unit aims to build a synergetic bridge between chemical synthesis and analytics in microreaction systems. Based on lab-on-a-chip technology, the researchers conduct fundamental work in the fields of microsynthesis on-chip and in flow-through reactors, integrating analytical concepts for the inline characterisation of chemical processes in real time. The resulting micro laboratories will be applied in various fields, including drug development, building substance libraries, controlling catalytic reactions, and in studies to elucidate reaction mechanisms.

Dynamics and Interactions of Semiconductor Nanowires for Optoelectronics (FOR 1616)
Semiconductor nanowires are ideal tools for investigating the fundamental boundaries of one-dimensional optoelectronic and photonic devices. So far, research has hardly gone beyond investigating the wires themselves. The next crucial step is the integration of nanowires into specific functional environments, so that their unique physical properties can be used, such as for efficient multicoloured LEDs or nanolasers at room temperature. The Dynamics and Interactions of Semiconductor Nanowires for Optoelectronics Research Unit has been investigating this since 2012.

Language and Culture in a Digital Age

enlarge the image: Language and Culture in a Digital Age research profile area
Diagram: Daniel Janetzki, Visionauten

Language and Culture in a Digital Age is a new research profile area designed to foster research cooperation between the humanities and computer science.

The main objective of this profile area is the establishment of research alliances to analyse forms of language and culture in the digital age, to apply methods of digitisation and to examine their significance in the present. The area sees itself as a useful bridge between computer science on the one hand and the humanities and social sciences on the other. The department sees itself as a bridge between computer science and the humanities and social sciences. It is also engaged in a critical discussion of methodological principles, the establishment of productive communication and jointly fathoming new forms of research, teaching and innovative publication.

Methods for the digital representation and analysis of sources in the humanities and social sciences (such as texts, images and music) are being applied and advanced. Just as important is a consideration of the significance of increasing digitisation for materials and analyses, processes of knowledge and culture transfer, and analyses of linguistic expression and language acquisition in educational processes.

The working group #digitalegegenwart, for example, conducts critical discussions on the significance of digital technologies and media. Research is also carried out from the perspective of general and single-language linguistics, for example into the formal representation of language, its diversity, processing, and individual language use and acquisition. A variety of collaborations between computer science and the humanities receive a high level of external funding, and their successes have been internationally recognised with the award of the Humboldt Professorship for Digital Humanities to Professor Gregory Crane.

Interaction of Grammatical Building Blocks (RTG 2011)

Research Training Group 2011, “Interaction of Grammatical Building Blocks” focuses on the phonology, morphology and syntax of natural languages. The doctoral candidates conduct wide-ranging, systematic studies of the possible interactions of grammatical building blocks from a range of theoretical perspectives. The basis for this is a multitude of detailed empirical investigations of phonological, morphological and syntactic phenomena from typologically different languages.

Current research projects include the Reinhart Koselleck Project Structure Removal in Syntax. A New Approach to Conflicting Representations.

Mathematical and Computational Sciences

Diagram: Daniel Janetzki, Visionauten

This research profile area covers mathematical and computational sciences in the broad sense: the dovetailing of mathematics, theoretical physics and computer science with natural sciences and medicine.

There is a particular focus on structural questions that arise directly from challenges in the natural sciences. These include exact mathematical models for physics, standardisations of field theories, limits of predictability, the nature of chance and computability, self-organisation of living matter, the structure of large networks, and how to handle large amounts of data. One goal is the identification of new applications.

Researchers in this profile area are for example involved in the DFG Research Training Group Quantitative Logics and Automata, the International Max Planck Research School “Mathematics in the Sciences”, and the Big Data Competence Centre “ScaDS Dresden/Leipzig”.

Quantitative Logics and Automata (RTG 1763)

Research Training Group 1763, “Quantitative Logics and Automata”, was established with the aim of comprehensively investigating quantitative logics and automata and their connection with methods of theoretical computer science. The results of this research could potentially be applied to problems from the areas of verification, knowledge representation, and the solution of constraint satisfaction problems. The Research Training Group is run in cooperation with the TU Dresden.

Strong Dynamics and Criticality in Quantum and Gravitational Systems (RTG 2522)

The aim of Research Training Group 2522, “Strong Dynamics and Criticality in Quantum and Gravitational Systems”, is to investigate and compute the emergence of complexity in gravitational and quantum field theories starting from their foundations. The working groups concentrate on examples of physical topicality or conceptual relevance, such as gravitational wave phenomena and black holes on the gravity side, and dynamics and criticality near phase transitions on the quantum side. The RTG is run in cooperation with the Friedrich Schiller University Jena.
