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,…
Entanglement of three-qubit geometry
Dorje C. Brody, Anna C. T. Gustavsson, Lane P. Hughston
Geometric quantum mechanics aims to express the physical properties of quantum systems in terms of geometrical features preferentially selected in the space of pure states. Geometr…
Faster than Hermitian Quantum Mechanics
Carl M. Bender, Dorje C. Brody, Hugh F. Jones +1
Given an initial quantum state |psi_I> and a final quantum state |psi_F> in a Hilbert space, there exist Hamiltonians H under which |psi_I> evolves into |psi_F>. Consider the follo…
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…
Quantum states and space-time causality
Dorje C. Brody, Lane P. Hughston
Space-time symmetries and internal quantum symmetries can be placed on equal footing in a hyperspin geometry. Four-dimensional classical space-time emerges as a result of a decoher…
