Abstract Electromagnetic anapole mode is a nonradiative state of light originating from the deconstructive interference radiation oscillating electric and toroidal dipole moments. The high quality anapole-related resonances can be used in enhancing nonlinear electromagnetic properties materials sensor applications. In this work, we experimentally demonstrate plasmonic metamaterial environmental...

It is well known that the Casimir force calculated at large separations using Lifshitz theory differs by a factor of 2 for metals described Drude or plasma models. We argue this difference entirely determined contribution transverse electric (s) evanescent waves. Taking into account there lack experimental information on electromagnetic response to low-frequency waves, we propose an experiment ...

Abstract In a system with broken inversion symmetry, second-order nonlinear Hall effect can survive even in the presence of time-reversal symmetry. this work, we show that giant exist twisted bilayer WTe 2 system. The Berry curvature dipole ( ? = 29.4°) reach up to ~1400 Å, which is much larger than previously reported systems. system, there abundant band anticrossings and inversions around Fer...

We use our recent electric dipole moment (EDM) measurement data to constrain the possibility that HfF$^+$ EDM oscillates in time due interactions with candidate dark matter axion-like particles (ALPs). employ a Bayesian analysis method which accounts for both look-elsewhere effect and uncertainties associated stochastic density fluctuations ALP field. find no evidence of an oscillating over ran...

Absorption of wave energy may be considered as a phenomenon of interference between incident and radiated waves generated by an oscillating object; a wave-energy converter (WEC) that displaces water. If a WEC is very small in comparison with one wavelength, it is classified as a point absorber (PA); otherwise, as a 'quasi-point absorber'. The latter may be a dipole-mode radiator, for instance a...

The vector potential is A=(μo/4π)qv/r, from which B=∇×A. Upon any acceleration of the charge, one finds a long range electric field, E=− ∂A/∂t. The range of this 1/r field far exceeds that from a charge, which goes as 1/r2 or a dipole which goes as 1/r3. This E field differs from Hertz’ solution for an oscillating charge. Hertz’ finding of TEM waves from an oscillating charge is flawed by the i...

classical trajectory (monte carlo) calculation is used to calculate collision rate constants of ion-quadrupolar molecule interactions for the h¯+c2h2 system. the method presented here takes into account the effect of the induced dipole-induced dipole potential on ion-quadrupolar molecule collision rate constants. it is also assumed that the colliding particles have a definite size. the thermal ...

Fundamental constants such as masses and coupling of elementary particles can have small temporal spatial variations in the scalar field dark-matter model. These entail time oscillations other constants, Bohr nuclear magnetons, radius, hyperfine structure constant. In presence an external magnetic field, these induce transitions atoms molecules. We determine probability dipole transitions, caus...

The present study is devoted to an approximate modeling for numerical simulation of flows past oscillating airfoils. In this study, it is shown that the harmonic oscillating objects can be studied by simple numerical codes that are not able to solve moving grids. Instead of using moving grid for the simulation of flowfield around an oscillating airfoil, this unsteady flow is solved on a fixed g...

We demonstrate that the vibrational nuclear motion of singly ionized argon dimers can be controlled with two ultrashort laser pulses of different wavelengths. In particular, we observe a striking "gap" in the pump-probe-delay-dependent kinetic-energy release spectrum only if the probe-pulse wavelength exceeds the pump-pulse wavelength. This "frustrated dissociation effect" is reproduced by our ...
