Almost-periodic time observables for bound quantum systems
Michael J. W. Hall
It is shown that a canonical time observable may be defined for any quantum system having a discrete set of energy eigenvalues, thus significantly generalising the known case of ti…

Consistent classical and quantum mixed dynamics
Michael J. W. Hall
A recent proposal for mixed dynamics of classical and quantum ensembles is shown, in contrast to other proposals, to satisfy the minimal algebraic requirements proposed by Salcedo…

Comment on "An Arrow of Time Operator for Standard Quantum Mechanics" - a sign of the time!
Michael J. W. Hall
It is shown that the `arrow of time' operator, M_F, recently suggested by Strauss et al., in arXiv:0802.2448v1 [quant-ph], is simply related to the sign of the canonical `time' obs…
