Radiation Pressure: Problem Solving

391
The radiation pressure applied by an electromagnetic wave on a perfectly absorbing surface equals the energy density of the wave. The wave's momentum also gets transferred to the surface when an electromagnetic wave is entirely absorbed by it. The rate at which momentum is transmitted to an absorbing surface perpendicular to the propagation direction equals the force on the surface.
The average value of the rate of momentum transfer divided by the absorbing area represents the average force...

Radiation: Applications

1.2K
The average temperature of Earth is the subject of much current discussion. Earth is in radiative contact with both the Sun and dark space; it receives almost all its energy from the radiation of the Sun and reflects some of it into outer space. Dark space is very cold, about 3 K, so Earth radiates energy into it. For instance, heat transfer occurs from soil and grasses, the rate of which can be so rapid that frost can occur on clear summer evenings, even in warm latitudes.
The average...

Super-resolution Fluorescence Microscopy

7.0K
Super-resolution fluorescence microscopy (SRFM) provides a better resolution than conventional fluorescence microscopy by reducing the point spread function (PSF). PSF is the light intensity distribution from a point that causes it to appear blurred. Due to PSF, each fluorescing point appears bigger than its actual size, and it is the PSF interference of nearby fluorophores that causes the blurred image. Various approaches to achieving higher resolution through SRFM have recently been...

Area of Science:

  • Theoretical physics
  • High-energy physics
  • Soliton dynamics

Background:

  • Q-balls are stable, particle-like configurations of scalar fields.
  • Nontopological solitons can exhibit complex dynamics, including rotation.
  • Superradiance is a wave amplification phenomenon occurring in the presence of rotating objects.

Purpose of the Study:

  • To investigate the phenomenon of superradiance in the context of Q-balls.
  • To explore how coherent rotations of Q-balls affect scattering waves.
  • To identify the conditions necessary for energy and angular momentum superradiance.

Main Methods:

  • Analysis of wave scattering in the presence of Q-balls.
  • Theoretical modeling of coupled mode interactions.
  • Investigation of frequency mismatches between modes.
  • Examination of real-space spin effects on superradiance.

Main Results:

  • Coherent Q-ball rotations induce superradiance for scattering waves.
  • Superradiance arises from the coupling of two modes with mismatched frequencies.
  • Incident wave energy and angular momentum are enhanced.
  • Real-space spin of Q-balls leads to additional rotational superradiance.

Conclusions:

  • Q-balls can act as a source of superradiance.
  • The frequency mismatch is crucial for energy and angular momentum enhancement.
  • Rotational superradiance offers a mechanism for further amplification.
