We use a local magnetic imaging technique, scanning SQUID microscopy, to map the spatial distribution of electronic states near surfaces and interfaces. We track conductivity, superconductivity and magnetism in systems undergoing phase transitions, where the local picture is particularly meaningful. I will describe two measurements: At the superconductor-insulator transition in NbTiN we map superconducting fluctuations and detect a non-trivial behavior near the quantum critical point. Near the metal to insulator transition at the 2D LaAlO3/SrTiO3 interface, we find that the conduction landscape changes dramatically and identify the way different types of defects control the behavior.

However, although existing retinal prostheses demonstrate proof of principle in treating incurable blindness, they produce limited visual function. Some of the reasons for this can be understood based on the exquisitely precise and specific neural circuitry that mediates visual signaling in the retina. Consideration of this circuitry suggests that future devices may need to operate at single-cell, single-spike resolution in order to mediate naturalistic visual function. I will show large-scale multi-electrode recording and stimulation data from the primate retina indicating that, in some cases, such resolution is possible. I will also discuss cases in which it fails, and propose that we can improve artificial vision in such conditions by incorporating our knowledge of the visual system in bi-directional devices that adapt to the host neural circuity. Finally, I will briefly discuss the potential implications for other neural interfaces of the future. -

Our group at Montana State University has pioneered all‐sky imaging methods to study skylight polarization and relate it to properties of airborne particles, clouds, and the underlying surface. Brief results from a deployment of all‐sky polarization imagers at the August 2017 solar eclipse will be shown and related to a more general discussion of atmospheric optical effects that can be seen by eye. The talk takes its title from my 2017 book, which describes optical phenomena in nature, especially as seen through airplane windows.

Forschungszentrum JulichOrganizer Department of Chemical and Biological PhysicsContact Abstract Show full text abstract about The cytoskeleton is a highly dynamic three-dimensional netwo...» The cytoskeleton is a highly dynamic three-dimensional network of polar filamentous proteins and molecular motors. It provides structural stability for biological cells and it also generates and transmits mechanical forces. For example, in mesenchymal cell motility actin filaments polymerize at their plus ends, which exerts pushing forces on the cell membrane. Here, we present a generic two-dimensional model for an active vesicle, where self-propelled filaments attached to semiflexible polymer rings form mechanosensitive self-propelled agents. We find universal correlations between shape and motility. To probe the internal dynamics of flexocytes, we study the effect of substrate patterning on their mechanical response. The active vesicles reproduce experimentally observed shapes and motility patterns of biological cells. They assume circular, keratocyte-like, and neutrophil-like shapes and show both persistent random and circling motion. Interestingly, explicit pulling forces only are sufficient to reproduce this cell-like behavior. Also for the reflection of the vesicles at walls and the deflection of their trajectories at friction interfaces we find parallels to the behavior of biological cells. Our model may thus serve as a filament-based, minimal model for cell motility. -

Quantum photonics for a new level of computer security and enhanced quantum computer architectures

Here I present that the exploit of quantum photonics allows for a variety of quantum-enhanced data security for quantum and classical computers. The latter is based on feasible hybrid classical-quantum technology, which shows promising new applications of readily available quantum photonics technology for complex data processing. At the end I will also show how optical quantum computers allow for novel architectures that rely on superimposed order of quantum gates. As outlook I will discuss technological challenges for the scale up of photonic quantum computers, and our group’s current work for addressing some of those.

Recently, sequential infiltration synthesis (SIS) was developed from atomic layer deposition (ALD) chemistry for selective growth of inorganic materials within polymers. In this talk, I will discuss SIS mechanism and growth process development as well as our work on combining BCP self-assembly with SIS for nanoparticle structuring, 3D imaging with TEM tomography, ultrafiltration membranes, and advanced 3D nanofabrication. -

CEITEC (the Central European Institute of Technology, BrnoOrganizer Department of Molecular Chemistry and Materials ScienceContact Abstract Show full text abstract about One-dimensional materials represent an attractive class of n...» One-dimensional materials represent an attractive class of nanostructures, mainly because of their geometry which inherently implies applications such as electrodes for sensing purposes or conduction channels in nanoscale electronics. Different mechanisms may be utilized to prepare nanowires, e.g. stress-driven one-dimensional diffusion, metal-catalyzed growth (VLS) etc. The most important role in identifying and description of the growth mechanisms is played by real-time microscopies, mostly TEM. However, although very powerfull in terms of image resolution, TEM is also limited in use, especially because of very strict sample geometry requirements. In this seminar talk, I will present our real-time in-situ scanning electron microscopy experiments of nanowire growth. Two different material systems will be presented – germanium nanowires catalyzed by Au nanoparticles and WOx nanowires. As for the latter case, our experiments reveal a very unusual oxidation mechanism of tungsten disulfide nanotubes, resulting in tungsten oxide nanowire formation. The talk will summarize studies on quasi-1D systems conducted at IPE and CEITEC BUT.
