Questions from past exam papers. 1. (a) (8 marks) The Hamiltonian
... (i) For the Hamiltonian Ĥ = p̂2 /2m + V( x̂) check that Ĥ, p̂ = i~ dV/dx. (ii) Interpret this result by developing the analogy between classical and quantum mechanics. (b) (6 marks) A quantum system can exist in two states |0i and |1i, which are normalised eigenstates of an observable A with eigen ...

Variational Monte Carlo studies of Atoms - DUO
... A crucial point is then to demand the potential, V , to be a time-independent potential as well, viz. V = V (x) (in one spatial dimension). This equation can be obtained by the well-known method of separation of variables. The trick is to write our wave function, Ψ(x, t), as a product of a purely sp ...

4.3 Notes - Denton ISD
... Students play “How do you know?” Give students several cards containing quadratic equations; some have real number solutions, others nonreal or complex solutions. In small groups, students draw a card and state whether the solution is real or not real. They then answer the question “How do you know? ...
