Lightwave driven quantum dynamics: from molecular movies to Bloch waves


Organisation: Max Planck Institute for the Science of Light / Russell Division

Speaker: Prof. Dr. Jens Biegert (ICFO - The Institute of Photonics Sciences, Castelldefels (Barcelona), Spain)

Place: MPL / room A.1.500


Electron recollision in an intense laser field is at the centre of attoscience research and gives rise to a variety of phenomena, ranging from electron diffraction to coherent soft X-ray emission. We have, over the years, developed intense sources of waveform controlled mid-IR light to exploit ponderomotive scaling, quantum diffusion and quasi-static photoemission.

I will describe how we leverage these effects to "teach" electrons to take a selfie of the dynamics of a single molecule. This permits visualizing for the first time, with combined attosecond temporal and atomic spatial resolution, molecular bond breaking and deprotonation. Furthermore, we achieve isolated attosecond pulses in the soft X-ray water window across the oxygen edge at 534 eV. Accomplishing ultrafast temporal resolution in combination with the soft X-ray's element specificity now provides an entirely new view on the combined electronic and nuclear dynamics in real time. I will show first results in which we resolve the carrier dynamics in a quantum material in real time and within the material's unit cell.

These results provide the first comprehensive insight into the dynamics of molecules and condensed matter, thus addressing fundamental and long-standing questions such as molecular isomerization, phase transitions and superconductivity, and a realistic route to possibly implement control over such processes.

MPL Distinguished Lecturer Series
Sensing and biosensing enabled by silicon photonics: opportunities and challenges


Prof. Roel Baets (Ghent University)


MPL, Room A1.500


In the past 10 years silicon photonics has matured to an industrially viable technology for high datarate transceivers for telecom and data center applications. In this presentation the question will be explored: what opportunities does the technology offer for sensing applications, in biosensing, in medical instruments? A variety of proof-of-concept examples will be discussed along with the associated scientific challenges.

IMPRS monthly meeting


Organisation: Katharina König (MPL/ Sandoghdar Division)

Talk: Single Protein Analytics

Speaker: Marek Piliarik (Institute of Photonics and Electronics of the Czech Academy of Sciences in Prague)

Place: MPL / room A.2.500


Understanding the structure and function of biological matter at nanoscale is among the most exciting challenges in modern microscopy. We aim at tracking the motion in biophysical system with a nanometer fidelity and at microseconds temporal resolution. We employ interferometric scattering microscopy (iSCAT) which is an optical microscopy technique capable of detecting and localizing extremely small scattering signals such as a few-nm particles or even unlabeled proteins. We explore new challenges arrising from ultra-fast tracking of scattering labels including fluctuations in the label position and background. Using this methodology we exploit unknown mechanisms of microtubule associated proteins revealing the choreography of its diffusible motion which were not to date deciphered.

IMPRS monthly meeting


Organisation: Pooria Hosseini, (MPL /Russell Division)

Talk: Raman spectroscopy as research tool in process technology

Speaker: Dr. Andreas Bräuer, Head of Applied Raman Scattering lab, FAU Erlangen-Nürnberg

Place: Bibliothek (A.2.500), MPL, Staudtstr.2, 91058 Erlangen

Date & Time: Thursday, 18 May 2017, 16:00Uhr


In process engineering the development and the projection of new processes is based on the knowledge of the thermodynamics and the transport processes. Here I will report Raman measurements for the determination of vapor-liquid-equilibria at high pressures and high temperatures (20 MPa and 750 K) and for the determination of mass transport phenomena in drying or spraying applications. While the vapor-liquid-equilibria are measured in micro capillaries, mass transport analysis is realized in common optically accessible high pressure cells.

Talk: Collective Behaviour of Cells in Dense Tissues

Speaker: Özer Duman, Forschungszentrum Jülich, Germany

Place: Bibliothek A.2.500, MPL, Staudtstr.2, 91058 Erlangen

Biological tissues show different phases of motility, generally described as nonmotile, jammed, and fluid-like phases. The different phases support particular functions. In wound healing, cells move collectively to close a wound. In tumors, cells evolve into a motile phenotype, during cancer metastasis. In in-vitro experiments, cell-cell contacts mature, leading to a glass-like arrest of the previously fluid-like tissue. For motile tissues, we distinguish generally an ordered and jammed solid-like phase and a disordered and migratory fluid-like phase. We develop a novel computational model of tissues wherein individual cells are extended objects with well defined physical properties. The model reproduces the solid-to-fluid and the reverse transition as a function of physical parameters. In particular, we find that cell-cell adhesion favours a solid-like phase, while motility and deformability lead to more fluid like structures.
