On quantum microcanonical equilibrium
Dorje C. Brody, Daniel W. Hook, Lane P. Hughston
A quantum microcanonical postulate is proposed as a basis for the equilibrium properties of small quantum systems. Expressions for the corresponding density of states are derived,…
Complex Trajectories of a Simple Pendulum
Carl M. Bender, Darryl D. Holm, Daniel W. Hook
The motion of a classical pendulum in a gravitational field of strength g is explored. The complex trajectories as well as the real ones are determined. If g is taken to be imagina…
On optimum Hamiltonians for state transformations
Dorje C. Brody, Daniel W. Hook
For a prescribed pair of quantum states |psi_I> and |psi_F> we establish an elementary derivation of the optimum Hamiltonian, under constraints on its eigenvalues, that generates t…
