Spin-Inversion Degeneracies in Restricted Inspiral Waveforms for LISA

Spin inversions appear in several settings. Analytical work predicts a single spin flip during unequal-mass supermassive binary inspiral, while numerical relativity and post-Newtonian calculations show repeated flip-flop motion in comparable-mass binaries. Secular spin evolution...

Exact analytical solutions for the piston effect in supercritical fluids under post-acoustic approximation — Short-time asymptotics, thermal penetration depth and comparison with the Spacelab D-2 experiments

Near the liquid–vapor critical point, fluids become highly compressible, giving rise to a special, strongly coupled thermo-mechanical process: the piston effect. In this phenomenon, a thin thermal boundary layer develops near a heated wall; owing to strong thermal expansion, this...

Shear‐Mode Direct Piezoelectric Response of Ferroelectric Nematic Liquid Crystals

ABSTRACT Piezoelectricity (linear coupling between mechanical deformation and electric signal) was originally observed only in solid crystals. Recently, it was discovered that liquid ferroelectric nematic liquid crystals are also piezoelectric. However, so far only their converse...

Measurements of the production of W$$^{\pm }$$ and Z$$^0$$ bosons in pp collisions at $$\sqrt{s} = 13$$ TeV

Abstract Measurements of the production of the W $$^{\pm }$$ ± and Z $$^0$$ 0 bosons at midrapidity in pp collisions at $$\sqrt{s} = 13$$ s = 13 TeV with ALICE at the Large Hadron Collider (LHC) are presented. The W $$^{\pm }$$ ± and Z $$^0$$ 0 bosons are detected via their (di)e...

Flying through the plasmasphere to optimize low-energy ion measurements

The Juice flyby of Earth in August 2024 gave us the first chance to evaluate the performance of the Jovian Plasma Dynamics and Composition analyzer (JDC) in environments similar to those expected at Jupiter. JDC is one of the sensors belonging to the Particle Environment Package...

Tumor border delineation in basal cell carcinoma using Fourier analysis

Basal cell carcinoma (BCC) is the most common malignancy in Caucasians. Surgical excision is the gold standard for treating BCC; however, poorly defined borders often challenge complete removal. Therefore, there is a need for efficient imaging techniques to enable visual and quan...

Bethe Ansatz with a Large Language Model

We explore the capability of a Large Language Model (LLM) to perform specific computations in mathematical physics: the task is to compute the coordinate Bethe Ansatz solution of selected integrable spin chain models. We select three integrable Hamiltonians for which the solution...

Step-ScanInterferometry for High-Fidelity HyperspectralNanoscopy

Abstract Fourier transform infrared nanospectroscopy (nano-FTIR) is an increasingly adopted characterization method that leverages decades of established knowledge in infrared spectroscopy at the nanoscale. It enables detailed characterization of composite materials and nanophoto...

Donor-SetSwitching in Morpholine-Functionalized 8-Hydroxyquinolines:Consequences for Metal Binding and the Bioactivity of RhCp* Complexes

Abstract Morpholine-functionalized 8-hydroxyquinoline (HQ) derivatives with reduced Schiff base linkers, Morph-Et-HQ and Morph-Pr-HQ, were synthesized and comprehensively characterized to investigate the influence of linker length on donor-set preference, metal binding, and the b...

Inscription of Quasi-Sinusoidal Surface Relief Optical Gratings in ZEONOR™ Cyclic Olefin Polymer by a 10.5 MeV N4+ Ion Microbeam at Low Implanted Fluences

Direct writing of microstructures in ZEONOR™ cyclic olefin polymer, using a high-energy medium-mass ion microbeam, was proposed and demonstrated. Microbeams of 10.5 MeV N4+ ions were used. The implanted fluences were between 2.5·1012 and 2.0·1013 ion/cm2. The microstructures were...
