I really disliked Star Wars E8 #TheLastJedi. I thought it wasn't just offensive to established canon of decades of #StarWars, it was obnoxiously derivative & just laden with bad storytelling.
I mean, when one's suspension of disbelief is repeatedly broken, that's a seriou…

Bose-Einstein Condensation, Fluctuations and Spontaneous Symmetry Breaking
The realisation of Bose-Einstein condensation under grand-canonical conditions has provided the experimental evidence for the simultaneous occurrence of macroscopic fluctuations and phase coherence of the condensate. The observation of these two features, against a consolidated tradition which wants the fluctuations to be pathological (grand-canonical catastrophe) and incompatible with spontaneous symmetry braking, calls for a comprehensive rethinking of the approach to the problem. In this pap…

Hi friends!
I set my alarm to 5am and headed out for a nice walk. It was getting warm, so I started early. - and it was just so good to do so!
A nice 6h walk with lots of views, lots of photos and just enjoying being out. End the #summit just for me 😍
On the way up I noted all places where I could refuel later using my water filter. Seriously: why didn't I buy that waaays ear…

A canonical Makanin-Razborov diagram and a pseudo topology for sets of tuples in free groups, semigroups, associative algebras and Lie algebras I
The JSJ decomposition and the Makanin-Razborov diagram were proved to be essential in studying varieties over free groups, semigroups and associative algebras. In this paper we suggest a unified conceptual approach to the applicability of these structures over all these algebraic categories. With a variety over each of these algebraic categories we naturally associate a set of tuples in a free group. Then we show how to associate a Makanin-Razborov diagram with any set of tuples over a free gro…

A Motivic Riemann-Roch Theorem for Deligne-Mumford Stacks
We develop a motivic cohomology theory, representable in the Voevodsky's triangulated category of motives, for smooth separated Deligne-Mumford stacks and show that the resulting higher Chow groups are canonically isomorphic to the higher $K$-theory of such stacks. This generalises the Grothendieck-Riemann-Roch theorem to the category of smooth Deligne-Mumford stacks.

The peculiar composition of the Sun is not related to giant planets
Highly-differential spectroscopic studies have revealed that the Sun is deficient in refractory elements relative to solar twins. To investigate the role of giant planets on this signature, we present a high precision abundance analysis of HARPS spectra for 50 F- and G-type stars spanning -0.4<[Fe/H]<+0.5. There are 29 stars in the sample which host planets of masses > 0.01 MJup. We derive abundances for 19 elements, and apply corrections to 14 of them for systematic errors associated with one …

Influence of microscopic parameters on phase behavior of a cell model with Curie-Weiss interaction
We have investigated the effect of changing two microscopic parameters in a cell model with Curie-Weiss-type interaction on its phase behavior, namely the cell volume and ratio between repulsion and attraction intensities. The results are based on an exact solution previously derived for this model in the grand canonical ensemble. At sufficiently low temperatures, the cell model exhibits multiple first-order phase transitions. Varying the cell volume and the repulsion-to-attraction ratio, we re…
