Reconstructing the wavefunction of magnetic topological insulators MnBi2Te4 and MnBi4Te7 using spin-resolved photoemission
Despite their importance for exotic quantum effects, the surface electronic structure of magnetic topological insulators MnBi2Te4 and MnBi4Te7 remains poorly understood. Using high-efficiency spin- and angle-resolved photoemission spectroscopy, we directly image the spin-polarization and orbital character of the surface states in both compounds and map our observations onto a model wavefunction to describe the complex spin-orbital texture, which solidifies our understanding of the surface band …

Merz dämpft Erwartungen an Trump-Gespräch
Kanzler Friedrich Merz hat die Bedeutung seines Treffens mit US-Präsident Donald Trump betont, zugleich aber zu große Erwartungen gedämpft. "Ich erwarte nicht, dass es große Durchbrüche in den drei genannten großen Themenbereichen geben wird", sagte Merz gegenüber deutschen Journalisten in Washington. Er freue sich aber auf das Gespräch. Die Hauptthemen seien der Krieg in der Ukraine,…

Ukraine-Liveblog: ++ Satellitenbilder zeigen Schäden an Flugzeugen ++
Nach dem ukrainischen Angriff vom Sonntag auf russische Militärstützpunkte sind auf Satellitenbildern Schäden an einigen Maschinen zu sehen. Im Norden der Ukraine sind bei Angriffen laut Behörden mindestens fünf Menschen getötet worden.

With so much hype and recent articles on "AI for coding" and how everyone not doing it is dumb maybe this is a good time to relink my article on "Vibe Coding".
Which I think focuses purely on "output" when developing or creating something is not just about the output.

Senior State Department staffer Darren Beattie,
a passionate Putin supporter behind the move to dismantle a key agency fighting Russian propaganda,
is married to a Russian woman whose uncle is a longtime Kremlin ally, according to The Telegraph.
Yulia Kirillova grew up in Moscow, studied abroad in North America, and married Beattie in 2021 in Florida.
She moved to D.C. in January.
Her uncle Sergei Cherniko is a drinks magnate who had an estimated net worth of $1…

Large Language Models are Locally Linear Mappings
We demonstrate that the inference operations of several open-weight large language models (LLMs) can be mapped to an exactly equivalent linear system for an input sequence without modifying the model weights or altering output predictions. Extending techniques from image diffusion models that exhibit local or piecewise linearity, we strategically alter the gradient computation with respect to a given input sequence for a next-token prediction such that the Jacobian of the model nearly exactly r…

NASA’s Goddard Institute for Space Studies (GISS)
has been a small-but-mighty source of world-changing scientific research for more than a half-century.
NASA scientists first moved into the building,
which another federal agency leases from GISS’s institutional partner, Columbia University, in 1966.
Last month, at the behest of the Trump administration,
NASA officials told GISS it had to move out before the end of May.
In response, more than 100 staffer…
