Self-organisation of proteins in cells
Prof. Erwin Frey, Arnold Sommerfeld Center - LMU Munich

Protein pattern formation is essential for the spatial organization of intracellular processes like cell division, and flagellum positioning. A prominent example of intracellular patterns is the oscillatory pole-to-pole oscillations of Min proteins in E. coli whose function is to ... more

Changing the Face of Greenhouse Gas Sensing with Optical Frequency Combs
Ian Coddington, NIST Boulder USA

The optical frequency comb is rapidly maturing from a laboratory curiosity to a critically enabling technology in areas ranging from dual-comb spectroscopy of atmospheric gasses, to precision time dissemination, to the search for earth sized exoplanets. This talk will focus on th ... more

A Journey through the Nano-world of Porous Silicon: From Theory to Praxis
Chris Burns, Director of The Porous Silicon Company

Today’s seminar takes a deep dive into the magical world of porous silicon. The journey begins describing multiple ways to manufacture and manipulate Silicon to create high surface area and high porosity substrates, films and particles. By orchestrating the Silicon dopant leve ... more

Towards single-molecule analysis with nanomechanical resonators
Prof. Silvan Schmid, Micro- and Nanosensors, Institute of Sensor and Actuator Systems, TU Wien

The identification and quantification of samples are a fundamental task in most applications in medicine, science and engineering. Mass spectrometry and absorption spectroscopy are two indispensable instrumental methods available in analytical chemistry today. While these are two ... more

Anomalous Transport in Correlated Quantum Matter
Prof. Dr. Michael Knap, Physics Department, Technical University Munich

Universality in equilibrium asserts that microscopic details are irrelevant for the emergent quantum phases of matter and their transitions. Rather, symmetries and topology determine the essential macroscopic properties. By contrast, all scales, from low to high energies, are rel ... more

Formation of moiré interlayer excitons in space and time
Prof. Stefan Mathias , I. Physikalisches Institut, Georg-August-Universität

Transition metal dichalcogenides (TMDs) are an exciting model system to study ultrafast energy dissipation pathways, and to create and tailor new emergent quantum phases [1,2]. The versatility of TMDs results from the confinement of optical excitations in two-dimensions and the c ... more

Chemical reaction dynamics of ions: from classical to quantum
Prof. Dr. Roland Wester, University of Innsbruck

To understand how chemical reactions proceed has been a goal of research in physics and chemistry for more than a century. In this talk I will show how single-collision experiments combined with product velocity map imaging and reaction dynamics calculations can provide detailed ... more

Controlling optical properties at the nanoscale: an (electro-)chemical approach
Prof. Gilles R. Bourret, Paris Lodron University of Salzburg

The optical and electrical properties of nanomaterials strongly depend on their composition and geometry at the nanoscale. The intrinsic constraints of conventional synthetic and lithographic techniques have limited the types of heterostructures that can be created and studied in ... more

Biophysical modelling of the role of geometry on tissue patterning and growth
John Dunlop, Paris-Lodron University of Salzburg

It is well known that the physical environment of growing cells and tissues plays an important role on their behaviour. In particular recent research has shown that the curvature of a substrate can influence the growth of a tissue and also the organisation of the extracellular ma ... more

Cancelled Chiral symmetry breaking in crystals
Yves Geerts, Université Libre de Bruxelles

Louis Pasteur and Pierre Curie have dreamed to direct chiral symmetry breaking using external magnetic and electric fields. [Chem. Rev. 1998, 98, 2391] Their attempts were unsuccessful because of time reversal symmetry has explained with theoretical considerations by Laurence Bar ... more

Single-photon sources and detectors for quantum based radiometry
Prof. Stefan Kück, Physikalisch-Technische Bundesanstalt

In this presentation, an overview of single photon sources and detectors is given with regard to their application in metrology, especially quantum radiometry. Single photon sources and detectors have a broad field of application, ranging from almost pure research areas such as q ... more

Ultrafast charge transfer in heterostructures of two-dimensional materials
Prof. Giulio Cerullo, Dipartimento di Fisica, Politecnico Milano

Heterostructures (HS) of two-dimensional materials offer unlimited possibilities to design new materials for applications to optoelectronics and photonics. In such HS the electronic structure of the individual layers is well retained because of the weak interlayer van der Waals c ... more

From quarks and gluons to exotic hadrons
Gernot Eichmann

With recent experimental evidence for tetraquarks and pentaquarks, hadron spectroscopy is nowadays a cutting-edge area of research with the LHC among its central facilities. Hadrons are bound states of quarks and gluons in QCD, the theory of the strong interaction, but their spec ... more
