Zeldzaam protest uit diplomatieke kring tegen Nederlands Israël-beleid
Diplomaten uiten zelden kritiek op regeringsbeleid. Toch spreken ervaren Nederlandse gezanten zich nu publiekelijk uit over het uitblijven van actiestappen tegen Israël.

Topological phase transitions between bosonic and fermionic quantum Hall states near even-denominator filling factors
We study the quantum critical point between the fermionic $ν=8$ quantum Hall state and the bosonic $ν=2$ quantum Hall state of Cooper pairs. Our study is motivated by the composite fermion construction for the daughter states of even-denominator fractional quantum Hall states and the experimentally observed transition between the daughter and the Jain states at the same filling. We show that this transition is equivalent to the transition between a neutral invertible $E_8$ state and a topolog…

Laser-induced ultrafast structural transformations in thin Fe layer revealed by time-resolved X-ray diffraction
The ultrafast response of iron lattice to sub-ps pulsed laser-induced heating has been investigated using time-resolved XRD in the partial melting regime. Strong electron-phonon coupling in Fe leads to rapid heating within 1-2 ps post laser-irradiation, followed by lattice expansion and melting on the 2-5 ps timescale. A tetragonal distortion of the remaining bcc-phase emerges at 6 ps and the unit-cell volume increases up to a value characteristic for the bcc-Fe phase. Under the experimental co…

Hölder maps from Euclidean spaces to Carnot groups
We give alternative proofs of (unsharp) results of Gromov's on his H\''older equivalence problem: for which $α$ does there exist a $C^α$-homeomorphism of an open set of Euclidean space to an open set of a given Carnot group? We indicate a possible route to sharp bounds.

AutoWISP: Automated Processing of Wide-Field Color Images
We have developed a software pipeline, AutoWISP, for extracting high-precision photometry from citizen scientists' observations made with consumer-grade color digital cameras (digital single-lens reflex, or DSLR, cameras), based on our previously developed tool, AstroWISP. The new pipeline is designed to convert these observations, including color images, into high-precision light curves of stars. We outline the individual steps of the pipeline and present a case study using a Sony-alpha 7R II …

Triples as Links between Binary Black Hole Mergers, their Electromagnetic Counterparts, and Galactic Black Holes
We propose a formation pathway linking black holes (BHs) observed in gravitational-wave (GW) mergers, wide BH-stellar systems uncovered by Gaia, and accreting low-mass X-ray binaries (LMXBs). In this scenario, a stellar-mass BH binary undergoes isolated binary evolution and merges while hosting a distant, dynamically unimportant tertiary stellar companion. The tertiary becomes relevant only after the merger, when the remnant BH receives a GW recoil kick. Depending on the kick velocity and syste…
