Densities in neutron star cores can reach up to ten times the density of a normal atomic
nucleus, and the stabilising effect of gravitational confinement
permits long-timescale
weak interactions. This generates matter that is neutron-rich, and opens up the
possibility of stable states of strange matter.

Over the past 25 years, extensive R&D has been carried out
on Monolithic Active
Pixel Sensors based on CMOS technology. This has brought the technology to the
level where it is now, a viable option for vertexing and tracking detection systems
in particle and nuclear physics
experiments
exposed to radiation fluencies

Light can hold, move and measure micro-
and nano particle without touching. Optical
tweezers exploit focused laser light to measure forces at the nanoscale and quantify
elasticity. Complex tailored light field based on holographic priniciples allow extending
this application range, making holographic optical tweezers to an extraordinary
metrology tool for analysis in biophysics and biophotonics.
This way, three dimensional configurations of micro-
and nano particles can be
generated in parallel and dynamically modified, creating spatially selective sensors.

Which features make the brain such a powerful and energy-efficient computing machine? Can we reproduce
them
in the solid state, and if so, what type of computing paradigm would we
obtain?

Die moderne Theorie komplexer Systeme trägt immer mehr zum Verständnis der
Kräfte und Wechselwirkungen bei, welche die
verwirrende Dynamik des globalen
Klimasystems auf allen Zeitskalen bewirken. Insbesondere ist es kürzlich gelungen,
die quasi
periodischen Vereisungen der Nordhemisphäre während der letzten 2,5 Mio.
Jahre weitgehend aufzuklären.

If black holes represent one of
the most fascinating implications of Einstein's theory of
gravity,
neutron stars in binary system are arguably its richest laboratory,
where gravity
blends with astrophysics and particle physics.

All living organisms consist of cells, and all cells are
built up from the same molecular
species and supramolecular assemblies.
Furthermore, as far as we know, the complex
behaviour of these living
cells obeys
the fundamental laws of physics and
thermodynamics.

This talk is devoted to versatile studies, whose common point is the fact that beta or gamma decay from polarized radioactive nuclei is anisotropic in space.
The experimental setup devoted to laser polarization of short-lived nuclei is located at the CERN-ISOLDE facility.

Local realism is the principle of locality (no instantaneous action-at-a-distance)
joined to realism (the world and its properties exist whether or not we observe
them).
While it is typical for philosophers to question realism, in physics (as in
common sense), realism was implicitly assumed until Niels Bohr and Wehner
Heisenberg introduced the anti-realist Copenhagen Interpretation in 1927.
Einstein's 1927-1935 arguments in support of local realism showed how Bohr's
position describes a radically different understanding of physics and our relation to
the physical world.
In 1964 John Bell gave local realism a mathematical form, and
showed that it was in principle testable. The first such Bell test was reported in
1970, and by now
several generations of physicists have grappled with the
problem of how to rigorously test a claim at the boundary of physics and
philosophy.

We investigated different kind of π–conjugated molecules in a combined scanning tunnelling (STM) and
atomic force microscope (AFM). Whereas both measurement channel
s show features with sub-molecular
resolution, the information they
can provide is truly complementary. For example, STM allows the direct
imaging of the unperturbed molecular orbitals [1], whereas the
AFM channel directly reveals the molecular
geometry. When applied to STM-based single-molecule synthesis and on-surface chemistry, the
combination of these techniques enables a direct quantification
of the interplay of geometry and electronic
coupling in real space

Rechnerarchitektur ist eine Disziplin, die das Verständnis
über die Funktionsweise
und die Struktur von Rechnern bearbeitet. Beginnt man mit den Betrachtungen der
von Neumann Architektur mit ihrer Idee des minimalen Hardwareaufwands, so
erkennt man sehr schnell, dass dieser grundlegenden Idee einige wichtige Elemente
fehlen.
