1D YIG hole-based magnonic nanocrystal
Magnetic media with artificial periodic modulation-magnonic crystals (MCs) - enable tunable spin-wave dynamics and band structure engineering. Nanoscaling enhances these capabilities, making magnonic nanocrystals promising for both fundamental studies and applications. Here, we report on the design, fabrication, and characterization of one-dimensional YIG MCs with nanoholes ($d \approx $ 150 nm) spaced $a \approx 1 μ$m apart. Micro-focused Brillouin light scattering and propagating spin-wave s…

Positivity of simplicial volume for closed nonpositively curved four-manifolds with nonzero Euler characteristic
In this paper, by employing the Gauss-Bonnet theorem for Riemannian simplices due to Allendoerfer and Weil, we show that if a closed nonpositively curved $4$-manifold has nonzero Euler characteristic, then its simplicial volume is necessarily positive. This result partially resolves conjectures posed by Connell-Ruan-Wang and Gromov concerning the relationship between the simplicial volume and the Euler characteristic for four-dimensional manifolds. As an application, we show that if a closed no…

Eh, final home for the time being. Once the second nameserver finishes updating I can get the cables managed a bit better. Either way, officially done.

Physics-informed Machine Learning Analysis for Nanoscale Grain Mapping by Synchrotron Laue Microdiffraction
Understanding the grain morphology, orientation distribution, and crystal structure of nanocrystals is essential for optimizing the mechanical and physical properties of functional materials. Synchrotron X-ray Laue microdiffraction is a powerful technique for characterizing crystal structures and orientation mapping using focused X-rays. However, when grain sizes are smaller than the beam size, mixed peaks in the Laue pattern from neighboring grains limit the resolution of grain morphology mapp…

Constructing strong starters of orders $3p$: triplication with SAT solver
A novel approach to building strong starters in cyclic groups of orders $n$ divisible by 3 from starters of smaller orders is presented. A strong starter in $Z_n$ ($n$ odd) is a partition of the set $\{1,2,\dots,n-1\}$ into pairs $\{a_i,b_i\}$ such that all pair sums $a_i+b_i$ are distinct and nonzero modulo $n$ and all differences $\pm(a_i-b_i)$ are distinct and nonzero modulo $n$. A special interest to strong starters of odd orders divisible by 3 is motivated by Horton's conjecture which clai…

Dygtige skribenter har en fantastisk forståelse for sprogets nuancer, helt ned (op?) på et fŸlelsesmæssigt niveau. Jeg har lige nydt Kathryn Schulz’ diskussion af fŸlelsen i ordet “og” (dvs. “and” fordi hun taler om engelsk, men pointerne er de samme for dansk) i Ezra Kleins podcast.
Man kunne tale om en tankens grammatik, en formning af vores tanker. Og “og” er vidunderlig fordi denne konjunktion kan sammensætte både det kongruente og det inkongruente, og samtidig peger ordet ind i f…

JWST Coronagraphic Images of 14 Her c: a Cold Giant Planet in a Dynamically Hot, Multi-planet System
Most observed multi-planet systems are coplanar, in a dynamically "cold" configuration of concentric orbits like our own Solar System. With the James Webb Space Telescope (JWST) we have detected 14 Her c, the first mature and cold exoplanet directly imaged in a dynamically "hot", multi-planet system. With large eccentricities and a nonzero mutual inclination, the present-day architecture of this system points to a turbulent past and ongoing angular momentum exchange between the planetary orbits…
