Electric and Magnetic Tau Dipole Moments Revisited [PDF]
arXivPrecise measurements of magnetic and electric dipole moments are important tests of the Standard Model and beyond Standard Model physics, particularly for the electron and the muon. However, the situation presents distinctive challenges when dealing with the tau lepton due to its very short lifetime and relatively high mass.

Advanced Materials Technologies, EarlyView.In situ, nanoparticle doping enhances the piezoelectric coefficient (**d₃₃**) of PVDF to ≈12 pC/N, while in situ growth of AgF and Ag₂O dopants increases β‐phase concentration. The nanogenerator achieves a 35 V open‐circuit voltage and 1.6 µA short‐circuit current, powering 10 blue LEDs and charging a 50 nF capacitor within 10 s.

Physical signatures of fermion-coupled axion dark matter
Journal of High Energy PhysicsIn the presence of axion dark matter, fermion spins experience an “axion wind” torque and an “axioelectric” force. We investigate new experimental probes of these effects and find that magnetized analogs of multilayer dielectric haloscopes can explore ...

The magnetic field of Mars estimated from the data of plasma measurements by Soviet artificial satellites of Mars [PDF]
The dimensions of the obstacle forming the shock wave of Mars are estimated by use of electron trap data from Mars 2, 3, and 5. The mean altitude of the obstacle at the subsolar point can be convincingly explained if the obstacle is the magnetosphere of ...

Predictive Design to Determine Optimal Absorber Placement in Colloidal Photonic Crystals
Advanced Optical Materials, EarlyView.The inclusion of absorbing material is known to increase color saturation in photonic crystals. Predictive design based on mathematical structure optimization is used to identify optimal designs for the absorber amount and position within a photonic colloidal crystal and experimentally realized. This strategy shows that the placement of the absorber at

Advanced Optical Materials, EarlyView.Light impinging from the left on a metasurface composed by active material. The metasurface shows asymmetric configuration through the non‐uniform presence of holes. The forming quasi‐BICs modes are exploited for lasing purposes. Abstract It is proposed and numerically demonstrated a novel strategy to achieve lasing generation from a dual‐band symmetry‐
