BroglieBohmféle

The Broglie-Bohm model, also known as de Broglie-Bohm theory or pilot-wave theory, is a deterministic interpretation of quantum mechanics. It was first proposed by Louis de Broglie in 1927 and later developed by David Bohm in 1952. Unlike the standard Copenhagen interpretation, which posits that quantum systems exist in a superposition of states until measured, the Broglie-Bohm model suggests that particles always have definite positions.

In this interpretation, a quantum particle is guided by a "pilot wave" that propagates according to the Schrödinger equation. This pilot wave, which is a complex-valued function, dictates the motion of the particle. The wave is not a physical entity in the classical sense but rather a mathematical construct that influences the particle's trajectory. The theory offers a deterministic explanation for quantum phenomena, meaning that if the initial position of a particle and the wave function are known, its future evolution is completely determined.

The Broglie-Bohm model reproduces all the observable predictions of standard quantum mechanics. However, it introduces the concept of "hidden variables" in the form of the definite particle positions, which are not directly observable in the same way as in the standard formulation. This interpretation has been a subject of ongoing debate among physicists due to its non-locality and the philosophical implications of having particles with predefined trajectories. Despite the controversy, it remains a viable interpretation of quantum mechanics.
