Was der Spiegel zum Sudhof-Bericht und zu Spahn schreibt, ist ziemlich harter Tobak - aber dieser Typus "Macher, der fachlichen Rat ignoriert und lieber auf Beziehungen setzt" scheint in der Union leider nicht selten zu sein.

Spahns Maskendeals: »Jetzt will ich rechtlich verbindlich das Zeug ;-)«
Der Sonderbericht zu den Maskengeschäften wird für Jens Spahn mit jeder Enthüllung gefährlicher. Nun geht es um hemdsärmlige Mails, die Deutschland Hunderte Millionen kosten könnten.

Nature-friendly farming budget swells in UK – but cuts elsewhere make recovery fraught
Progress on nature-positive farming – but habitats still trail big-ticket technology

It's all go on the harvest around here. Very very busy farmers. Loads of tractors hauling those big grain trailers. Dusty tails blowing across the roads. It's great to see.

Chiral interactions of fermions and massive gauge fields in Kaluza-Klein models
In Kaluza-Klein theory, gauge fields on $M_4$ arise as components of a higher-dimensional metric defined on $M_4 \times K$. The traditional expectation is that all the gauge fields of the Standard Model are linked to exact Killing vector fields on the internal space. This paper questions that assumption and investigates the properties of 4D gauge fields linked to non-Killing fields on $K$. It is shown that they have massive yet arbitrarily light bosons; they can mix fermions with different mass…

Made a plain-ass cheese pizza last night but the crust worked really well with just a 24 hour ferment on the counter. Sometimes simple is all you need.

Quench dynamics of negativity Hamiltonians
In this paper, we investigate the quench dynamics of the negativity and fermionic negativity Hamiltonians in free fermionic systems. We do this by generalizing a recently developed quasiparticle picture for the entanglement Hamiltonians to tripartite geometries. We obtain analytic expressions for these quantities which are then extensively checked against previous results and numerics. In particular, we find that the standard negativity Hamiltonian contains both non-local hopping terms and four…

Refining ensemble $N$-representability of one-body density matrices from partial information
The $N$-representability problem places fundamental constraints on reduced density matrices (RDMs) that originate from physical many-fermion quantum states. Motivated by recent developments in functional theories, we introduce a hierarchy of ensemble one-body $N$-representability problems that incorporate partial knowledge of the one-body reduced density matrices (1RDMs) within an ensemble of $N$-fermion states with fixed weights $w_i$. Specifically, we propose a systematic relaxation that redu…
