Detection of Black Holes

Detection of Black Holes

Although black holes were theoretically postulated in the 1920s, they remained outside the domain of observational astronomy until the 1970s.
Their closest cousins are neutron stars, which are composed almost entirely of neutrons packed against each other, making them extremely dense. A neutron star has the same mass as the Sun but its diameter is only a few kilometers. Therefore, the escape velocity from their surface is close to the speed of light.
Not until the 1960s, when the first neutron...

The Wave Nature of Light

The Wave Nature of Light

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.

The Quantum-Mechanical Model of an Atom

The Quantum-Mechanical Model of an Atom

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.

The de Broglie Wavelength

The de Broglie Wavelength

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...

The Bohr Model

The Bohr Model

Following the work of Ernest Rutherford and his colleagues in the early twentieth century, the picture of atoms consisting of tiny dense nuclei surrounded by lighter and even tinier electrons continually moving about the nucleus was well established. This picture was called the planetary model since it pictured the atom as a miniature “solar system” with the electrons orbiting the nucleus like planets orbiting the sun. The simplest atom is hydrogen, consisting of a single proton as...

Area of Science:

Quantum optics
Holography
Photonics

Background:

Classical holography uses light interference for object reconstruction.
Detection limitations exist for non-visible wavelengths, restricting applications.
Nonclassical states of light offer potential solutions to these limitations.

Purpose of the Study:

To implement phase-shifting holography using nonclassical light.
To overcome detection constraints for imaging outside the visible spectrum.
To demonstrate object imaging without direct photon detection.

Main Methods:

Utilizing quantum interference between two-photon probability amplitudes.
Employing a nonlinear interferometer.
Implementing phase-shifting holography with nonclassical states of light.

Main Results:

Spatial shape (amplitude and phase) of photons is retrieved without detection.
Object imaging is achieved despite photons never being detected.
A well-characterized reference beam is not required due to the two-photon scheme.

Conclusions:

Quantum holography enables imaging beyond detection limits of classical methods.
This technique advances sensing and imaging for non-visible wavelengths.
The two-photon approach simplifies the holographic setup by self-referencing.
