Photoreceptors and Visual Pathways01:22

Photoreceptors and Visual Pathways

10.4K
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category,...

Maxwell's Equation Of Electromagnetism

4.2K
James Clerk Maxwell (1831–1879) was one of the major contributors to physics in the nineteenth century. Although he died young, he made major contributions to the development of the kinetic theory of gases, to the understanding of color vision, and to understanding the nature of Saturn's rings. He is probably best known for having combined existing knowledge on the laws of electricity and magnetism with his insights into a complete overarching electromagnetic theory, which is...

Dual Nature of Electromagnetic (EM) Radiation01:10

Dual Nature of Electromagnetic (EM) Radiation

4.6K
Electromagnetic (EM) radiation consists of electric and magnetic field components oscillating in planes perpendicular to each other and mutually perpendicular to radiation propagation through space. EM radiation can be classified as a wave, characterized by the properties of waves such as wavelength (denoted as λ) and frequency (represented by ν).
Wavelength is the distance between two consecutive peaks (the highest point) or troughs (the lowest point) in the wave. Frequency is the number of...

Thomson's e/m Experiment

7.3K
In a beam of charged particles created by a heated cathode, the particles move at different speeds. However, many applications need a beam with uniform particle speeds. An arrangement known as a velocity selector uses electric and magnetic fields to pick particles with a particular speed from the beam.
A particle with charge q, speed v, and mass m enters an area from the top, where the magnetic and electric fields are perpendicular both to the particle's motion and to one another. The magnetic...

Energy Carried By Electromagnetic Waves01:22

Energy Carried By Electromagnetic Waves

4.0K
Anyone who has used a microwave oven knows there is energy in electromagnetic waves. Sometimes, this energy is obvious, such as in the summer sun's warmth. At other times, it is subtle, such as the unfelt energy of gamma rays, which can destroy living cells. Electromagnetic waves bring energy into a system through their electric and magnetic fields. These fields can exert forces and move charges in the system and, thus, do work on them. However, there is energy in an electromagnetic wave,...

Potential Due to a Polarized Object01:29

Potential Due to a Polarized Object

859
A neutral atom consists of a positively charged nucleus surrounded by a negatively charged electron cloud. When placed in an external electric field, the external electric force pulls the electrons and nucleus apart, opposite to the intrinsic attraction between the nucleus and the electrons. The opposing forces balance each other with a slight shift between the center of masses of the nucleus and the electron cloud, resulting in a polarized atom. On the other hand, a few molecules, like water,...

Area of Science:

  • Particle Physics
  • Cosmology
  • High Energy Physics

Background:

  • Dark photons and axions are leading candidates for light particles in the hidden sector.
  • Searches for these particles primarily utilize the vector portal and axion portal couplings.
  • A gap exists in understanding potential interactions beyond these established portals.

Purpose of the Study:

  • To introduce and define a new interaction portal between dark photons and axions, termed the dark axion portal.
  • To demonstrate that this portal represents genuinely new couplings, distinct from products of existing portals.
  • To present a model realizing this portal and explore its phenomenological implications.

Main Methods:

  • Theoretical modeling of particle interactions.
  • Analysis of coupling structures beyond simple products.
  • Identification of a specific model realizing the proposed portal.

Main Results:

  • A novel dark axion portal connecting dark photons and axions has been identified.
  • This portal arises from the internal structure of couplings, not merely a combination of known portals.
  • A simple model demonstrating the existence of the dark axion portal has been constructed.

Conclusions:

  • The dark axion portal provides a new and distinct mechanism for interaction between dark photons and axions.
  • This new portal warrants further investigation due to its potential for rich phenomenology.
  • Future research should focus on experimental searches and theoretical elaborations of the dark axion portal.
