Particle traps are devices designed to capture and hold small particles, such as atoms or molecules, using various techniques. These traps can utilize electromagnetic fields, laser light, or other forces to confine particles in a specific area, allowing scientists to study their properties and behaviors in detail. One common type of particle trap is the Paul trap, which uses oscillating electric fields to capture charged particles. Another example is the optical trap, which employs focused laser beams to hold neutral particles. These tools are essential in fields like quantum physics and atomic physics, enabling advancements in research and technology.
