Summary
We explore phonon-photon interactions in a hybrid system using giant atoms. Phonons control photon transport, enabling tunable optical properties for quantum technologies.
Area of Science:
- Quantum Optics
- Condensed Matter Physics
- Quantum Information Science
Background:
- Waveguide quantum electrodynamics (QED) systems are crucial for controlling quantum states.
- Hybrid systems integrating phonons and photons offer novel control mechanisms.
- Giant atoms provide enhanced light-matter interaction capabilities.
Purpose of the Study:
- To investigate single photon scattering in a phonon-photon hybrid system within the waveguide QED framework.
- To demonstrate phonon-mediated control over photon transport.
- To explore the impact of giant atom properties on optical response.
Main Methods:
- Utilizing a giant atom coupled to a surface acoustic wave resonator and a coupled resonator waveguide (CRW).
- Analyzing nonlocal coupling and interference effects for photon transport control.
- Examining the influence of coupling strength and detuning on transmission spectra.
Main Results:
- Phonons act as controllers for photon transport in the waveguide.
- Coupling strength modulates transmission valleys/windows.
- Rabi splitting features transform with detuning, indicating effective dispersive coupling.
Conclusions:
- Giant atoms in hybrid systems offer tunable control over photon transport.
- Phonon-photon interactions can be leveraged for advanced quantum optical devices.
- This work highlights potential applications of giant atoms in hybrid quantum systems.

26.0K
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...

01:28Standing Waves in a Cavity
962
A household microwave and lasers are examples of standing electromagnetic waves in a cavity. When two conducting metal plates are placed parallel at the nodal planes, it creates a cavity where standing waves are formed. The cavity between the two planes is analogous to a stretched string held at the points x = 0 and x = L. Here, the distance 'L' between the two planes must be an integer multiple of half of the wavelength. The wavelengths that satisfy this condition are given by:

02:18The Bohr Model
56.4K
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...

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...
