Summary
Stable dissipative surface solitons in exciton-polariton condensates are controlled by localized resonant pumps. Pump frequency and array properties dictate soliton formation, amplitude, and bistability, with noise influencing excitation branches.
Area of Science:
- Condensed Matter Physics
- Nonlinear Optics
- Quantum Optics
Background:
- Exciton-polariton condensates exhibit unique quantum phenomena.
- Dissipative solitons are self-organized localized states in open systems.
- Microcavity arrays provide a platform for studying light-matter interactions.
Purpose of the Study:
- Investigate the formation of stable dissipative surface solitons.
- Analyze the control mechanisms for soliton properties.
- Explore the role of periodic structures and pumping in soliton dynamics.
Main Methods:
- Numerical simulations of the GPE model for exciton-polariton condensates.
- Analysis of localized resonant pumping in a 1D microcavity pillar array.
- Examination of the influence of pump frequency, array band gap, and spatial period.
Main Results:
- Surface soliton formation is controllable via pump frequency and array band gap.
- Bistability and nonlinearity-induced resonance shifts are observed.
- Increased spatial period enhances surface soliton amplitude.
- Soliton excitation depends on noise levels and bistability branches.
Conclusions:
- Localized resonant pumping enables control over dissipative surface solitons in microcavity arrays.
- The interplay between periodic structures and pump parameters is crucial for soliton dynamics.
- Understanding these solitons advances the study of nonlinear phenomena in quantum systems.

01:12Double Resonance Techniques: Overview
644
Double resonance techniques in Nuclear Magnetic Resonance (NMR) spectroscopy involve the simultaneous application of two different frequencies or radiofrequency pulses to manipulate and observe two distinct nuclear spins. One important application of double resonance is spin decoupling, which selectively suppresses coupling with one type of nucleus while observing the NMR signal from another nucleus, simplifying the spectrum and enhancing resolution.

01:14Sound Waves: Resonance
3.1K
Resonance is produced depending on the boundary conditions imposed on a wave. Resonance can be produced in a string under tension with symmetrical boundary conditions (i.e., has a node at each end). A node is defined as a fixed point where the string does not move. The symmetrical boundary conditions result in some frequencies resonating and producing standing waves, while other frequencies interfere destructively. Sound waves can resonate in a hollow tube, and the frequencies of the sound...

01:28Standing Waves in a Cavity
1.4K
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:

01:26Resonance in an AC Circuit
2.4K
The property of an inductor makes it resist any change in the current passing through it, while the property of a capacitor is to build up the charge across its terminals. Hence, if an inductor and capacitor are connected in series, they have opposite effects on the relative phase between current and voltage. The current through the circuit undergoes forced oscillation at the frequency of the source. The resistance term in an R-L-C circuit acts as a damping term because power is dissipated...

01:23Parallel Resonance
469
The parallel RLC circuit is an arrangement where the resistor (R), inductor (L), and capacitor (C) are all connected to the same nodes and, as a result, share the same voltage across them. The parallel RLC circuit is analyzed in terms of admittance (Y), which reflects the ease with which current can flow. The admittance is given by:

01:29Potential Due to a Polarized Object
692
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,...
