The decoherence of an electron wave packet due to the which path trace left in a conducting (metallic) plate placed under the electron trajectories is calculated using the many-body quantum description of the electron gas reservoir. WebSep 19, 2024 · To get interference, you need a precise path difference between two beams of light. If you have a wide slit, light could have passed in many places - and from there to the screen there are many different path lengths possible. When this happens, you don't get a clear interference pattern. important events in modernism https://mechanicalnj.net
