News (Jan. '21):
The FWF
has approved my project "Blackbox quantum
information under spacetime symmetries".
There will soon
be an announcement of available postdoc
and PhD positions (see e.g. IQOQI
Vienna homepage).
Media coverage
 The Born rule has been derived from simple
physical principles. Quanta
magazine, February 2019. Discusses paper 48
below (with Lluís Masanes and Thomas Galley), and
related work by Adán Cabello. See also the article on
Science
Alert, two blog posts in English language (#1 and
#2),
and piqd.de.
There is also an excellent description of our work in
German by Martin Bäker on his blog "Hier
wohnen Drachen".
 Faster than allowed by quantum computing?
(Answer: no!) Marius' and my paper 46 below has
received some media attention, including the Austrian
newspaper Der
Standard (see also here
and here),
APA,
Tiroler
Tageszeitung, BrightSurf.com,
R&D
Magazine, Health
Medicine Network (yes, that's somewhat
surprising...), phys.org,
Space
Daily, innovationsreport,
newswise,
EurekAlert!
and others. Note that our work builds very strongly on
earlier work, ideas, and insights by Lluís Masanes,
Gonzalo de la Torre, and Tony Short (see in particular
paper 27 below).

 What if there are no laws of nature? New
Scientist title story of November 2017, and New
Scientist, January 2020 on "reality"; see paper
51 below. There is also a Less
Wrong blog post and this FQXi
article from January 2019, and an article in the
Israeli newspaper Haaretz.
For a first introduction to this approach,
please have a look at this
seminar talk on YouTube, or read my short FQXi Essay,
paper 8 below. Further posts include one by Ian
Durham (FQXi) and a mention on a blog on Learning
Machines.
 Our results on the BerryKeating conjecture
(paper 40) have been exaggerated by some media (e.g. the
Wire), which in turn has led to criticism (e.g.
here).
To clarify: no, our work will almost certainly not
lead to significant progress on the Riemann
conjecture! But we think it is an interesting insight,
and yes,
it can be made mathematically rigorous. See also

Reference Frame, phys.org,

 Why space has exactly three dimensions.
New
Scientist, September 2013. Discusses some
approaches towards this question, including our paper
30 below.
 Quantum causality: information insights.
Nature
Physics
8, 860 (2012). Article by Terry Rudolph on
recent work by the quantum foundations community,
including our work on the structure of space and
quantum theory (papers 27 and 30).
 Classical problem becomes undecidable in a
quantum setting. Phys.org,
July 2012. Popularscientific description of paper 28
below. See also this FQXi
article (Searching for the Impossible) from
January 2015, and see the related independent works by
Toby Cubitt, David PérezGarcía and Michael Wolf,
including this
amazing result.
 And thus the quantum. Nature
Physics 7, 519 (2011) research highlights. This
summarizes paper 23, where we show that the Hilbert
space formalism of quantum theory can be reconstructed
from five simple physical/informationtheoretic
postulates.

Science writing by myself (about work by
others)
Early research before university
 Experimental disproof of an alleged antigravity
experiment ("Schnurer's experiment"), with
Josip Milanovic and FranzJosef Schmitt (1999).
At that time, a popular German TV broadcast claimed
that a superconductor could yield an antigravity
effect in a simple experiment. Thus, we went to the
lab at University Erlangen and reproduced the
experiment. We found that Schnurer seems to have
misinterpreted a simple buoyancy effect.
 "Fractional sums": how to add a noninteger
number of terms (around 1998).
This idea led to several publications with Dierk
Schleicher (for example this one),
and made the first prize at the German youth science
fair "Jugend forscht" 1998 in mathematics and computer
science, together with an exceptional prize by the
Federal President.
 Higherorder arithmetic operations, and
noninteger iteration of functions (19941995).
The main idea is written up in a little document here. It made the
second prize at "Jugend forscht", and an exceptional
prize by the Federal Chancellor.
