Social Traps01:41

Social Traps

26.9K
Social traps are negative situations where people get caught in a direction or relationship that later proves to be unpleasant, with no easy way to back out of or avoid. The concept was orignally introduced by John Platt who applied psychology to Garrett Hardin's "Tragedy of the Commons", where in New England herd owners could let their cattle graze in the common ground. This situation seems like a good idea, but an individual could have an advantage. If they owned...

Light Acquisition02:16

Light Acquisition

9.6K
In order to produce glucose, plants need to capture sufficient light energy. Many modern plants have evolved leaves specialized for light acquisition. Leaves can be only millimeters in width or tens of meters wide, depending on the environment. Due to competition for sunlight, evolution has driven the evolution of increasingly larger leaves and taller plants, to avoid shading by their neighbors with contaminant elaboration of root architecture and mechanisms to transport water and nutrients.

Light as Energy

96.1K
The energy required to carry out photosynthesis is light— typically electromagnetic radiation from the sun. The range of all possible wavelengths is known as the electromagnetic spectrum.
Photons
A photon is a discrete electromagnetic particle or bundle of energy. Photons are characterized by their frequency, wavelength, and amplitude, similar to the properties of a wave. Waves with higher frequencies transmit more energy and have shorter wavelengths than longer wavelengths that transmit...

The Wave Nature of Light02:12

The Wave Nature of Light

61.5K
The nature of light has been a subject of inquiry since antiquity. In the seventeenth century, Isaac Newton performed experiments with lenses and prisms and was able to demonstrate that white light consists of the individual colors of the rainbow combined together. Newton explained his optics findings in terms of a "corpuscular" view of light, in which light was composed of streams of extremely tiny particles traveling at high speeds according to Newton's laws of motion.

Photoreceptors and Plant Responses to Light

28.5K
Light plays a significant role in regulating the growth and development of plants. In addition to providing energy for photosynthesis, light provides other important cues to regulate a range of developmental and physiological responses in plants.

Focusing of Light in the Eye01:16

Focusing of Light in the Eye

6.1K
Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...

Area of Science:

  • Photonics
  • Condensed Matter Physics
  • Topological Materials

Background:

  • Topological insulators exhibit protected edge states preventing back-scattering.
  • These edge states enable unidirectional waveguides for photonic circuits.
  • Cavity modes lack topological protection due to lower dimensionality.

Purpose of the Study:

  • To demonstrate a novel mechanism for topological light-trapping in lower dimensions.
  • To investigate the creation of robust cavity modes using dual-topology.
  • To explore applications in photonic integrated circuits.

Main Methods:

  • Theoretical proposal of concurrent wavevector and real-space topology (dual-topology).
  • Experimental realization of photonic-bound states in a two-dimensional photonic crystal.
  • Characterization of the Jackiw-Rebbi soliton mode localized on a dislocation.

Main Results:

  • Demonstrated dual-topology enabling light-trapping in lower dimensions.
  • Observed a Jackiw-Rebbi soliton mode, a strongly confined cavity mode.
  • Showcased the robustness of the topological light-trapping against perturbations.

Conclusions:

  • Unveiled a new mechanism for topological light-trapping in lower dimensions.
  • The discovered photonic-bound state offers robustness and strong confinement.
  • This finding is valuable for fundamental physics and photonic applications.
