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…
Complete positivity for time-dependent qubit master equations
Michael J. W. Hall
It is shown that if the decoherence matrix corresponding to a qubit master equation has a block-diagonal real part, then the evolution is determined by a one-dimensional oscillator…
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…
Finding the Kraus decomposition from a master equation and vice versa
Erika Andersson, Jim D. Cresser, Michael J. W. Hall
For any master equation which is local in time, whether Markovian, non-Markovian, of Lindblad form or not, a general procedure is reviewed for constructing the corresponding linear…
