Quantum Numbers

It is said that the energy of an electron in an atom is quantized; that is, it can be equal only to certain specific values and can jump from one energy level to another but not transition smoothly or stay between these levels.

Interference and Diffraction

51.9K
Interference is a characteristic phenomenon exhibited by waves. When two electromagnetic waves interact with their peaks and troughs coinciding, a resulting wave with enhanced amplitude is produced. This is known as constructive interference. In this case, the two waves interacting are in phase with each other.

The Quantum-Mechanical Model of an Atom

56.8K
Shortly after de Broglie published his ideas that the electron in a hydrogen atom could be better thought of as being a circular standing wave instead of a particle moving in quantized circular orbits, Erwin Schrödinger extended de Broglie’s work by deriving what is now known as the Schrödinger equation. When Schrödinger applied his equation to hydrogen-like atoms, he was able to reproduce Bohr’s expression for the energy and, thus, the Rydberg formula governing hydrogen spectra.

RNA Interference01:23

RNA Interference

27.9K
RNA interference (RNAi) is a process in which a small non-coding RNA molecule blocks the post-transcriptional expression of a gene by binding to its messenger RNA (mRNA) and preventing the protein from being translated.
This process occurs naturally in cells, often through the activity of genomically-encoded microRNAs. Researchers can take advantage of this mechanism by introducing synthetic RNAs to deactivate specific genes for research or therapeutic purposes. For example, RNAi could be used...

Area of Science:

  • Quantum optics
  • Biomedical imaging
  • Photonics

Background:

  • Optical-Coherence Tomography (OCT) uses low-coherence light for internal structure imaging of semitransparent samples.
  • Quantum-OCT (QOCT) leverages entangled photon pairs from spontaneous parametric down-conversion (SPDC) for potential resolution enhancement and dispersion cancellation.
  • Standard QOCT employs photon pairs with strict spectral anti-correlations.

Purpose of the Study:

  • To revisit and extend the theoretical model of QOCT to accommodate photon pairs with arbitrary spectral correlations.
  • To present experimental results validating the extended QOCT theory.
  • To explain the physical mechanisms behind interference patterns in QOCT.

Main Methods:

  • Theoretical extension of QOCT models to include arbitrary spectral correlations.
  • Experimental implementation using SPDC with a pump source ranging from continuous wave to femtosecond pulsed.
  • Analysis of interference patterns and cross-correlation effects.

Main Results:

  • Demonstration that QOCT with arbitrary spectral correlations can achieve resolution enhancement and dispersion cancellation.
  • Experimental validation of the extended theoretical framework.
  • Observation that cross-correlation interference effects can be suppressed with sufficient pump bandwidth.

Conclusions:

  • The extended QOCT theory provides a more comprehensive understanding of the technique.
  • Arbitrary spectral correlations in entangled photons offer flexibility in QOCT implementations.
  • The findings offer practical strategies for advancing QOCT technology.
