Summary
Few-cycle laser pulses can induce localized plasmon oscillations in optical near-fields. Researchers compared nanoresonators, finding silver bow-ties and gold/silver dimers optimal for few-cycle near-field amplification.
Area of Science:
- Strong-field physics
- Ultrafast science
- Plasmonics
Background:
- Few-cycle laser pulses are crucial for strong-field physics and ultrafast science.
- Localized plasmon oscillations in optical near-fields are of significant interest.
Purpose of the Study:
- To investigate the induction of few-cycle localized plasmon oscillations.
- To comparatively study different plasmonic nanoresonators under few-cycle pulse illumination.
Main Methods:
- Comparative analysis of plasmonic nanoresonators (monomers and dimers).
- Illumination with few-cycle laser pulses.
- Evaluation of Number of Cycles (NOC), Near-Field Enhancement (NFE), and NFE/NOC figure of merit.
- Investigation of pulse length dependence.
Main Results:
- Silica-gold and silica-silver core-shell monomers preserve the incoming pulse's NOC.
- Silver bow-ties exhibit the highest Near-Field Enhancement (NFE).
- Gold core-shell dimers achieve the highest NFE/NOC figure of merit.
Conclusions:
- Silver bow-ties, gold core-shell, and silver nanorod dimers are highly suitable for few-cycle near-field amplification.
- These nanostructures offer potential for advanced applications in ultrafast science and strong-field physics.

01:30Oscillations In An LC Circuit
2.9K
An idealized LC circuit of zero resistance can oscillate without any source of emf by shifting the energy stored in the circuit between the electric and magnetic fields. In such an LC circuit, if the capacitor contains a charge q before the switch is closed, then all the energy of the circuit is initially stored in the electric field of the capacitor. This energy is given by

Stability is an important concept in oscillation. If an equilibrium point is stable, a slight disturbance of an object that is initially at the stable equilibrium point will cause the object to oscillate around that point. For an unstable equilibrium point, if the object is disturbed slightly, it will not return to the equilibrium point. There are three conditions for equilibrium points—stable, unstable, and half-stable. A half-stable equilibrium point is also unstable, but is named so...

In the real world, oscillations seldom follow true simple harmonic motion. A system that continues its motion indefinitely without losing its amplitude is termed undamped. However, friction of some sort usually dampens the motion, so it fades away or needs more force to continue. For example, a guitar string stops oscillating a few seconds after being plucked. Similarly, one must continually push a swing to keep a child swinging on a playground.

01:11Atomic Nuclei: Larmor Precession Frequency
2.4K
The earth's gravitational field produces a 'twisting force' perpendicular to the angular momentum of a spinning mass (such as a spinning top) that causes the mass to 'wobble' around the gravitational field axis in a phenomenon called precession. Similarly, the magnetic moment (μ) of a spinning nucleus precesses due to an external magnetic field directed along the z-axis. The precession of the magnetic moment vector about the magnetic field is called Larmor precession,...

When an oscillator is forced with a periodic driving force, the motion may seem chaotic. The motions of such oscillators are known as transients. After the transients die out, the oscillator reaches a steady state, where the motion is periodic, and the displacement is determined.

The vacuum level denotes the energy threshold required for an electron to escape from a material surface. It is usually positioned above the conduction band of a semiconductor and acts as a benchmark for comparing electron energies within various materials.
Electron affinity in semiconductors refers to the energy gap between the minimum of its conduction band and the vacuum level and it is a critical parameter in determining how easily a semiconductor can accept additional electrons.
