Kolloquium

Thema:

Multiplexed Optical Imaging by means of Spatial Light Modulators

Datum:

29.05.17

Uhrzeit:

16:15

Ort:

H6

Vortragender:

Prof. Dr. Monika Ritsch-Marte

Medizinische Universität Innsbruck, Department f. Physiologie und Medizinische Physik

Inhalt:

Synthetic holography by means of programmable phase masks on spatial light modulators allows one to create multiplexed holograms. Integrating SLM- wavefront shaping into an optical imaging system, enables multiplexed imaging, where every image consists of sub-images corresponding, for instance, to different depth layers in the imaged object or, in for quantitative phase microscopy, to different parameter settings. Multi-plane imaging and parallelized confocal imaging are used to demonstrate the potential of the approach.

Non-orthogonality of eigenvectors from the Haagerup-Larsen theorem

Uhrzeit:

Ort:

Vortragender:

Wojciech Tarnowski

Jagiellonian University Krakow

Inhalt:

Biunitarily invariant ensembles have been thoroughly studied in recent years from the point of view of statistics of eigenvalues. An enhanced symmetry of the probability distribution function allows us to expect that all spectral properties will be determined by the singular values only. Indeed, for large matrices, a mapping between one-point densities is known as the Haagerup-Larsen theorem. Recently, this mapping has been extended to all k-point functions (Kieburg-Kösters). During my talk, I will present a recent extension of the Haagerup-Larsen theorem, which gives a simple mapping between the radial spectral cumulative distribution function and a certain one-point eigenvector correlation function, built out of (non-orthogonal) left- and right eigenvectors. I will discuss also its relation with the stability of the spectrum.

Polyanalytic Ginibre ensembles

Datum:

17.05.17

Uhrzeit:

16:15

Ort:

V3-201

Vortragender:

Antti Haimi

Universität Wien

Inhalt:

We will discuss Polyanalytic Ginibre ensembles, a family of determinantal processes describing planar free fermions in a constant magnetic field. A physical interpretation is that a fixed number of first Landau levels are filled with particles. The classical Ginibre process corresponds to the case where only the lowest level is occupied. We will study the limiting behaviour as the magnetic field strength tends to infinity.
