Summary
We demonstrate a novel method to simulate topological physics using a single optical cavity. This approach allows for the observation of topological properties and edge states, opening new avenues for photonic research.
Area of Science:
- Quantum physics
- Photonics
- Condensed matter physics
Background:
- Topological physics explores unique states of matter with robust properties.
- Simulating these systems often requires complex experimental setups.
- Optical cavities offer controllable platforms for quantum simulations.
Purpose of the Study:
- To propose a scheme for simulating topological physics within a single degenerate optical cavity.
- To enable the implementation of open boundary conditions in an effective lattice system.
- To probe topological properties via edge states and cavity field spectra.
Main Methods:
- Mapping cavity modes to lattice sites.
- Constructing a sharp boundary to implement open boundary conditions.
- Analyzing the spectrum of an output cavity field to detect edge states.
Main Results:
- Successfully demonstrated the simulation of a static Su-Schrieffer-Heeger chain.
- Showcased the simulation of a periodically driven Floquet topological insulator.
- Confirmed that topological properties manifest as observable edge states.
Conclusions:

1.6K
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:

The starting point for expressing the modes of standing waves is understanding the boundary conditions that the waves must follow. The boundary conditions are derived from the physical understanding of how the standing waves are sustained, that is, how the vibrating particles of the medium behave at the boundaries imposed on them.
For a tube open at one end and closed at the other filled with air, the modes are such that there is always an antinode at the open end and a node at the closed end....

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...

A close look at earthquakes provides evidence for the conditions appropriate for resonance, standing waves, and constructive and destructive interference. A building may vibrate for several seconds with a driving frequency matching the building's natural frequency of vibration; this produces a resonance that results in one building collapsing while the neighboring buildings do not. Often, buildings of a certain height are devastated, while other taller buildings remain intact. This...
