Resumen
Los modelos cuánticos de cristales de tiempo fotónicos revelan que las brechas de momento clásicas provienen de transiciones de fase cuánticas. Esto conduce a una desintegración irreversible en las oscilaciones de Rabi atómicas, abriendo nuevas vías en la fotónica cuántica.
Sus antecedentes:
- Los cristales de tiempo fotónicos exhiben fenómenos como la amplificación de ondas debido a la modulación periódica en el tiempo.
- El comportamiento cuántico de los cristales de tiempo fotónicos acoplados a dipolos atómicos no se comprende bien.
- Las descripciones clásicas de los cristales de tiempo fotónicos no capturan completamente sus manifestaciones cuánticas.
Conclusiones:
- Los cristales de tiempo fotónicos proporcionan una plataforma para estudiar la fotónica cuántica fuera del equilibrio.
- La ingeniería del dominio del tiempo puede controlar las interacciones luz-materia.
- Se observó un nuevo fenómeno cuántico de decaimiento irreversible a un estado mixto.

02:32The de Broglie Wavelength
32.9K
In the macroscopic world, objects that are large enough to be seen by the naked eye follow the rules of classical physics. A billiard ball moving on a table will behave like a particle; it will continue traveling in a straight line unless it collides with another ball, or it is acted on by some other force, such as friction. The ball has a well-defined position and velocity or well-defined momentum, p = mv, which is defined by mass m and velocity v at any given moment. This is the typical...

02:12The Wave Nature of Light
60.6K
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.

02:45The Quantum-Mechanical Model of an Atom
56.4K
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.

3.8K
Electromagnetic waves can travel in the vacuum as well as in matter. For example light, which is an electromagnetic wave, can travel through air, water, or glass.
Consider the electromagnetic wave passing through a dielectric medium. In such a case, Maxwell's equations get modified. In Ampere's law, ε0 , the dielectric permittivity of free space is replaced with ε, the permittivity of dielectric. Also, the vacuum permeability μ0 is replaced by the permeability of the medium, μ.

02:26Photoelectric Effect
38.7K
When light of a particular wavelength strikes a metal surface, electrons are emitted. This is called the photoelectric effect. The minimum frequency of light that can cause such emission of electrons is called the threshold frequency, which is specific to the metal. Light with a frequency lower than the threshold frequency, even if it is of high intensity, cannot initiate the emission of electrons. However, when the frequency is higher than the threshold value, the number of electrons ejected...

01:24Electromagnetic Wave Equation
2.1K
Maxwell's equations for electromagnetic fields are related to source charges, either static or moving. These fields act on a test charge, whose trajectory can thus be determined using suitable boundary conditions. The objective of electromagnetism is thus theoretically complete.
However, although electric and magnetic fields were first introduced as mathematical constructs to simplify the description of mutual forces between charges, a natural question emerges from Maxwell's equations:...
