👉 In mathematical logic, a "semiclassical" object is an object that can be defined in terms of classical concepts but not as a classical object itself. Semiclassicals are often used to model complex phenomena or systems with inherent complexity and non-classical properties. For example, in physics, a semiclassical theory might describe the behavior of a quantum system where the probability density function (PDF) is governed by classical laws, such as the Poisson distribution for particles in classical mechanics.
