Thursday 18. May 2017

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

Abstract: 

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.

IMPRS monthly meeting

 

Organisation: Yazgan Tuna, (MPL /Sandoghdar Division)

Talk: Collective Behaviour of Cells in Dense Tissues

Speaker: Özer Duman, Forschungszentrum Jülich, Germany

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

Date & Time: Thursday , 04 May 2017, 15:00 h

Abstract: 

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.

Two-day Scientific Writing Workshop

 

Instructors: Justin Mullins & Mark Buchanan, WAS (Write About Science), London

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

Date & Time: Thursday & Friday, 30-31 March 2017, 09:00-17:00 h

Attendance: IMPRS-PL students

Course description: 

The Scientific Writing Workshop teaches the skills for producing high quality papers. A main focus of the course is the structure of good communication. So the workshop includes sessions on the structure of sentences, of paragraphs, abstracts and entire papers.We also explain how journals choose the papers they publish, we discuss editing, group editing and graphics. We have a wide range of thought-provoking exercises to emphasise the learning objectives and to allow students to practice the competences we teach. One of the most valuable aspects of the course is the one-to-one feedback we give to each participant. Ahead of the workshop, we ask each attendee to write an abstract about their work. We then prepare detailed line-by-line feedback that we give to each student during the second day.

IMPRS monthly meeting

 

Organisation: Golnoush Shafiee, (MPL /Leuchs Division)

Talk: Narrowband Quantum Light Sources for Quantum Memories

Speaker: Professor Hugues de Riedmatten, ICFO-The Institute of Photonic Sciences, Barcelona, Spain

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

Date & Time: Friday, 17 February 2017, 11:00 h

Abstract: 

Photonic quantum memories are important devices in quantum information science as they provide a quantum interface between flying and stationary qubits. The ability to store a quantum state of light enables the synchronization of different probabilistic quantum processes, which in turns allows the realization of scalable quantum networks and quantum repeaters. The realization of photonic quantum memories require strong interactions between photons and matter, which puts stringent requirements on the spectral properties of the photons to be stored.

In this talk, I will describe two approaches to generate storable single photons compatible with quantum memories based on rare-earth doped solids and laser cooled rubidium atoms.  The first approach is based on the generation of narrowband non-degenerate photon pairs compatible with solid-state quantum memories and telecom fibers, using cavity enhanced spontaneous down-conversion. This approach recently led to the first demonstration of quantum correlations between a telecom photon a multimode spin-wave solid-state quantum memory. The second approach involves the realization of a photon pair source with embedded quantum memory, using spontaneous Raman scattering in ensembles of atoms. A recent experiment demonstrating the generation of narrowband and synchronizable single photons with highly tunable wave shape from a cold atomic ensemble of Rubidium atoms will be described, as well as the first demonstration of a solid-state photon pair source with embedded multimode memory.
