Exact trapping state dynamics for the 85Rb atom micromaser at very high Q and/or very low T

Amitabh Joshi

Matrix continued fraction methods pioneered previously [1–3] are used to solve essentially exactly the dynamics of the one 85Rb atom micromaser. Ranges of cavity Q values, of average atomic input rates R = T p −1 and of atomic interaction times t int are studied with the principal aim of minimizing the cavity field variance v. As expected for T p ≳ 200t int the system does evolve to a steady state with v < 1 and sub-Poissonian photon statistics. But even Q = 5 × 1010 and temperature T = 0·070 K are apparently insufficient conditions for avoiding evolution to a steady state with v < 0 when t int = 1·54/(44 kHz) unless T p is also substantially reduced. Only in this way is actual trapping state dynamics obtained for this value of t int, while no example is found where the system evolves to v = 0 and a single Fock state is produced. The field variance v considered alone is not a good diagnostic for observing such trapping state dynamics and more information will be needed in order to describe adequately the cavity field.

Exact trapping state dynamics for the 85 Rb atom micromaser at very high Q and/or very low T

We have used matrix continued fraction methods pioneered previously, to solve essentially exactly for the dynamics of the one 85Rb atom micromaser. A range of cavity Q values and of average atomic input rates R equals Tp-1 and of atomic interaction times tint is studied. For Tp approximately greater than 200tint the system does evolve to a steady state. And even Q equals 5 multiplied by 1010 and temperature T equals 0.070 degrees K are apparently insufficient to avoid evolution to a steady state with finite variance of the cavity field when tint equals 1.54/44 kHz unless Tp is also substantially reduced. Only in this way are actual trapping state dynamics obtained. The field variance v is not a good diagnostic for observing such trapping state dynamics.
