|July 21, 2015
Summary
This study demonstrates generating polariton solitons (PSs) in semiconductor microcavities by using the Stark effect. Optimizing Stark pulse parameters allows for control over bright PS formation and polarization.
Area of Science:
- Condensed Matter Physics
- Quantum Optics
- Semiconductor Nanostructures
Background:
- Polariton solitons (PSs) are fundamental nonlinear phenomena in semiconductor microcavities.
- Controlling the generation and properties of PSs is crucial for potential applications.
- Existing methods for PS generation often lack precise control over their characteristics.
Purpose of the Study:
- To propose and investigate a novel method for generating polariton solitons (PSs).
- To utilize the Stark effect as a trigger mechanism for PS formation.
- To explore the tunability of PS properties through Stark pulse optimization.
Main Methods:
- Employing a Stark pulse as a 'writing beam' to excite non-resonant polariton fluctuations.
- Simulating the evolution of these fluctuations into bright polariton solitons.
- Systematically varying Stark pulse parameters to analyze their impact on PS solutions.
Main Results:
- Demonstrated the successful generation of bright polariton solitons using the Stark effect.
- Identified a branch of PS solutions controllable by adjusting Stark pulse parameters.
- Established that the polarization of the generated PS is directly dependent on the writing Stark beam.
Conclusions:
- The Stark effect provides an effective and controllable mechanism for generating polariton solitons.
- Optimizing Stark pulse parameters offers a pathway to tune PS properties, including polarization.
- This method opens new avenues for the study and application of nonlinear polaritonics in semiconductor microcavities.

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
1.7K
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:

01:28Induced Electric Dipoles
5.1K
A permanent electric dipole orients itself along an external electric field. This rotation can be quantified by defining the potential energy because the external torque does work in rotating it. Then, the potential energy is minimum at the parallel configuration and maximum at the antiparallel configuration. While the former is a stable equilibrium, the latter is an unstable equilibrium.
Since the absolute value of potential energy holds no physical meaning, its zero value can be chosen as per...

6.7K
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...

The fact that emfs are induced in circuits implies that work is being done on the conduction electrons in the wires. What can possibly be the source of this work? We know that it’s neither a battery nor a magnetic field, as a battery does not have to be present in a circuit where current is induced, and magnetic fields never do any work on moving charges. The source of the work is in fact an electric field that is induced in the wires. For example, if a stationary conductor is placed in a...

An understanding of the solvating effect helps rationalize the relation between solvation and acidity of the compound. In addition, this also explains the relative stability of conjugate bases for compounds with different pKa values. This lesson details, in-depth, the principle of solvating effects. The strength of an acid and the stability of its corresponding conjugate base are determined using pKa values. This observed relationship is a consequence of solvation, which is the interaction...
