Summary
Stable bright microcavity solitons are demonstrated in semiconductor microcavities. These solitons are supported by the exciton polariton nonlinearity and confined using a novel waveguide structure.
Area of Science:
- Condensed matter physics
- Quantum optics
- Semiconductor physics
Background:
- Exciton polaritons in semiconductor microcavities exhibit unique properties under strong coupling.
- The dispersion relation of these polaritons can possess regions of both positive and negative curvature.
Purpose of the Study:
- To investigate the existence and properties of stable one-dimensional bright microcavity solitons.
- To propose a method for achieving transverse confinement of these solitons.
Main Methods:
- Analysis of the lower polariton branch dispersion relation.
- Theoretical modeling of soliton formation and stability.
- Proposal of a waveguide structure based on cavity detuning for transverse confinement.
Main Results:
- Demonstration of stable one-dimensional bright microcavity solitons.
- Identification of the role of repulsive polariton nonlinearity in soliton support.
- Design of a waveguide structure for transverse localization by manipulating cavity detuning.
Conclusions:
- Stable bright microcavity solitons can be realized in semiconductor microcavities.
- The proposed waveguide method offers a viable route for creating localized polaritonic structures.

01:29Potential Due to a Polarized Object
A neutral atom consists of a positively charged nucleus surrounded by a negatively charged electron cloud. When placed in an external electric field, the external electric force pulls the electrons and nucleus apart, opposite to the intrinsic attraction between the nucleus and the electrons. The opposing forces balance each other with a slight shift between the center of masses of the nucleus and the electron cloud, resulting in a polarized atom. On the other hand, a few molecules, like water,...
01:28Standing Waves in a Cavity
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:
01:31Dielectric Polarization in a Capacitor
The presence of a dielectric medium in a capacitor not only changes the voltage and capacitance but also affects the electric field. In general, dielectrics can be of two types: polar and nonpolar. In a polar dielectric, the positive and negative charges in the molecules are separated by a distance and hence have a permanent dipole moment. In contrast, no such charge separation exists in a nonpolar dielectric, however the nonpolar molecules get polarized in the presence of an external electric...
02:54Molecular and Ionic Solids
Crystalline solids are divided into four types: molecular, ionic, metallic, and covalent network based on the type of constituent units and their interparticle interactions.
Molecular Solids
Molecular crystalline solids, such as ice, sucrose (table sugar), and iodine, are solids that are composed of neutral molecules as their constituent units. These molecules are held together by weak intermolecular forces such as London dispersion forces, dipole-dipole interactions, or hydrogen bonds, which...

01:01Group Polarization
Group polarization is the strengthening of an original group attitude following the discussion of views within a group (Teger & Pruitt, 1967). That is, if a group initially favors a viewpoint, after discussion the group consensus is likely a stronger endorsement of the viewpoint. Conversely, if the group was initially opposed to a viewpoint, group discussion would likely lead to stronger opposition.
01:01Energy Bands in Solids
Isolated atoms have discrete energy levels that are well described by the Bohr model. And, it quantifies the energy of an electron in a hydrogen atom as En. Higher quantum numbers 'n' yield less negative, closer electron energy levels.
Band Formation:
When atoms are brought close together, as in a solid, these discrete energy levels begin to split due to the overlap of electron orbitals from adjacent atoms. This split occurs because of the Pauli exclusion principle, which states that no two...
