It is the assumption that in a typical ensemble particle positions are distributed according to |psi|^2.cryptist said:What are the quantum equilibrium conditions in dBB?
Because it is the most probable distribution. (This is similar to the fact that in classical mechanics thermodynamic equilibrium is the most probable distribution.)cryptist said:Why our universe is in quantum equilibrium?
It seems that we cannot do that at will.cryptist said:How can disrupt that equilibrium? In labs, can we create any little universes that are not in quantum equilibrium?
The de Broglie-Bohm theory, also known as the pilot-wave theory, is an interpretation of quantum mechanics that proposes the existence of hidden variables that determine the behavior of quantum particles. These hidden variables, called "pilot-waves," guide the particle's motion in a deterministic way, in contrast to the probabilistic behavior predicted by the traditional Copenhagen interpretation of quantum mechanics.
Quantum equilibrium is a key concept in the de Broglie-Bohm theory. It refers to the state in which the pilot-waves and the quantum particles are in perfect balance, resulting in the observed probabilistic behavior of the particles. This equilibrium is maintained through the guidance equation, which ensures that the particle's position is always correlated with its pilot-wave.
In the de Broglie-Bohm theory, the behavior of particles in the double-slit experiment is determined by both their particle nature and their wave nature. The pilot-wave guides the particle through one of the slits, while the wave nature of the particle allows it to interfere with itself, resulting in the observed interference pattern on the detector screen.
The de Broglie-Bohm theory is a complete and self-consistent theory, but it is not widely accepted by the scientific community. It provides an alternative interpretation of quantum mechanics and makes the same predictions as the traditional Copenhagen interpretation. However, it introduces additional assumptions and complexities, making it less favored than the Copenhagen interpretation.
The measurement problem in quantum mechanics refers to the issue of how a quantum system transitions from a probabilistic state to a definite state when observed. In the de Broglie-Bohm theory, the pilot-wave guides the particle to a definite position at the moment of observation, eliminating the need for a collapse of the wave function. This resolves the measurement problem in a different way than the Copenhagen interpretation, which relies on the concept of wave function collapse.
