An elegant solution of the n-body Toda problem
Arlen Anderson
The solution of the classical open-chain n-body Toda problem is derived from an ansatz and is found to have a highly symmetric form. The proof requires an unusual identity involvin…
Clocks and Time
Arlen Anderson
A general definition of a clock is proposed, and the role of clocks in establishing temporal pre-conditions in quantum mechanical questions is critically discussed. The different s…
Evolving Constants of Motion
Arlen Anderson
A critical presentation of Rovelli's ``evolving constants of motion'' is given. Previous criticisms by Kuchař concerning the role of factor ordering and the non-existence of observ…
Unitarity Restoration for the Product of Nonunitary Operators
Arlen Anderson
A proof is given that the polar decomposition procedure for unitarity restoration works for products of invertible nonunitary operators. A brief discussion follows that the unitari…
