    Trapping and manipulating superconducting vortices by artificial pinning landscapes
    Tailored artificial pinning defects allow to investigate many ways of flux quanta manipulation, like guided vortex motion, vortex ratchets, flux-flow transistors and other cutting-edge concepts. The critical state of a superconductor with a regular pinning array is different from the classical one and will be explored by various electrical transport measurements. The project will be embedded in a European research network (COST) that started recently and provides regular training schools and international contacts. The successful candidate should have a solid background in Solid State Physics. Experience in superconductivity, low-temperature techniques, and magneto-transport measurement methods is welcome.

    Stochastic and quantum thermodynamics with levitated particles
    Two research positions are open in research at the interface of experimental levitated optomechanics and stochastic thermodynamics. The successful candidates will further develop new experimental platforms for optical trapping in vacuum. In parallel we will design and implement experiments that apply the new technologies to tackle experimentally yet unexplored phenomena in single- and few particle statistical physics and investigate the interface of thermodynamics and information theory. We aim at pushing these experiments into the quantum regime.
    1. An SLM-based optical trap for levitation: Spatial light modulators (SLMs) have enabled an impressive level of performance in control and readout of optically trapped objects in liquid. Optical traps in vacuum have thus far made nearly no use of these possibilities. Within the project, an SLM based optical trap for complex potential landscapes will be developed.
    2. Reservoir engineering of levitated particles: Based on our know-how in cavity control of levitated particles, a platform to engineer non-thermal and non-classical baths for the center-of-mass motion of nanoparticles will be developed. This also includes the design of a superior mechanism to transfer nanoparticles to the optical cavity.

    Single-atom manipulation in the electron microscope 
    An experimental PhD position in the ERC Starting Grant project ATMEN. Despite more than fifty years of scientific progress since Richard Freynman's 1959 vision for nanotechnology, there is only one way to manipulate individual atoms in materials: scanning tunneling microscopy. Scanning transmission electron microscopy, on the other hand, has been able to resolve atoms only more recently by focusing the electron beam with sub-atomci precision. The scattering of the energetic imaging electrons was recently found to move a silicon impurity through the graphene lattice, revealing the potential for atomically precise manipulation using the Angström-sized elecron probe. To develop this into a practical technique, advances in heteroatom implantation and a concerted effort towards their characterization and manipulation are required. The ideal candidate is familiar with electron microscopy and/or ion implantation, but a strong background in material science or nanotechnology may suffice.

    1. Airborne measurements of the complex refractive index of atmospheric aerosol layers
    In April 2017, the A-LIFE aircraft field experiment (www.a-life.at) was conducted in the Eastern Mediterranean to investigate the properties of absorbing aerosol layers (mineral dust-black carbon mixtures) during their atmospheric lifetime. The overall aim of this PhD project is to determine the complex refractive index of single aerosol particles in complex aerosol mixtures. This includes the characterization and further development of a novel instrument for vertically‐resolved measurements of complex refractive index and size of single aerosol particles, the analysis of data from the A-LIFE field experiment, and the collection and analysis of new data.

    2. Properties of aerosol mixtures in the Eastern Mediterranean during the A-LIFE aircraft field experiment.
    Recently it has been shown that the climate impact of black carbon (BC) is twice as large as originally thought. Due to the rather short lifetimes of BC in the atmosphere (on the order of days to weeks, compared to decades and longer for the main greenhouse gases) as well as its strong warming potential, BC reduction and mitigation strategies are expected to provide climate benefits. However, the attribution of absorption to different aerosol types is challenging. In particular in aerosol mixtures it is still an open research question whether mineral dust absorption is frequently misclassified as BC absorption. The overall aim of this ERC-funded PhD project is to study the partitioning between mineral dust and BC absorption in aerosol mixtures which we investigated during the A-LIFE field experiment (www.a-life.at) in the Eastern Mediterranean in April 2017. This project includes the analysis of in-situ size distribution data of total aerosol and BC, the derivation of optical properties, and the assessment of mineral dust and BC contribution to the total absorption for the investigated aerosol layers.

    Nucleation and growth rate measurements from anthropogenic precursors in chamber and field experiments
    An open PhD position is currently available in the framework of a Marie Sklodowska-Curie Innovative Training Network called CLOUD-MOTION. The successful candidate will conduct experimental studies of nanoparticle formation using cutting-edge instrumentation for nanoparticle detection and sizing. This work will partly be performed at the CLOUD experiment at CERN, Switzerland. In addition, field experiments in Vienna are planned to investigate urban nucleation.
