It is the foundation of all quantum physics including Visa mer In the mathematically rigorous formulation of quantum mechanics, the state of a quantum mechanical system is a vector $${\displaystyle \psi }$$ belonging to a (separable) complex Hilbert space $${\displaystyle {\mathcal {H}}}$$. This vector is postulated … Visa mer Quantum mechanics has had enormous success in explaining many of the features of our universe, with regards to small-scale and discrete quantities and interactions which … Visa mer Since its inception, the many counter-intuitive aspects and results of quantum mechanics have provoked strong philosophical debates … Visa mer Quantum mechanics allows the calculation of properties and behaviour of physical systems. It is typically applied to microscopic systems: molecules, atoms and sub-atomic … Visa mer Free particle The simplest example of a quantum system with a position degree of freedom is a free particle in a single spatial dimension. A free … Visa mer Classical mechanics The rules of quantum mechanics assert that the state space of a system is a Hilbert space and that observables of the system are Hermitian operators acting on vectors in that space – although they do not tell us which … Visa mer
