 # Quantum Mechanics: Fundamental Concepts

Subject Physics Quantum Physics

## Question

Qustions:
(a) In what sense is quantum mechanics fundamentally indeterministic?
Give two physical examples of such indeterminacy in real systems.
(b) Describe the role of the Heisenberg uncertainty principle in undermining the Newtonian description of the state of a system.
(c) Outline the role of the wave function in describing the state of an isolated system in one-dimensional wave mechanics. Is the description given
by the wave function as complete as can be? Discuss whether the indeterminacy of quantum mechanics arises from our lack of knowledge of the time-evolution of the wave function in between measurements (as described by Schrodinger’s equation), or whether it has another origin.
(d) Describe the role of eigenvalue equations in determining which energy values are possible in abound system. Are there any situations in which quantum mechanics unambiguously predicts the result of an energy measurement with certainty? How does the collapse of the wave function influence the result of an energy measurement taken immediately after another energy measurement?
(e) Explain the roles of the overlap and coefficient rules in predicting the probability of obtaining a given value when an energy measurement is made
in a given state.
(f) Explain the role of Born’s rule in predicting the probability of finding a particle within a given interval? How does the collapse of the wave function
influence the result of a position measurement taken immediately after another position measurement?
(g) Finally give a brief summary of the types of prediction that are possible in quantum mechanics. Comment on the extent to which these predictions
can (in principle) be compared with experiment by, for example, making repeated measurements.
