Darboux transformation of coherent states

Vladislav G. Bagrov, B. F. Samsonov, L. A. Shekoyan

It is proved that the Darboux transformation of the system of coherent states of a free particle leads to the states that may be treated as coherent states of soliton-like potentials.

Dynamics of pulsed SU(1,1) coherent states

Christopher C. Gerry, Edward R. Vrscay

In this paper we consider the time evolution of SU(1,1) coherent states driven by a coherence-preserving Hamiltonian containing periodic or quasiperiodic pulsing terms. This is a generalization of a system consisting of a two-level atom subjected to quasiperiodic pulsing that was recently studied by Milonni, Ackerhalt, and Goggin [Phys. Rev. A 35, 1714 (1987)]. The time-evolution operator in our case is given by a product of two finite group transformations of SU(1,1). Assuming an initial SU(1,1) coherent state, we determine the equivalent classical motion generated by a Poincar\'e map that is a M\"obius transformation on the Lobachevski plane, the interior of the unit circle in the complex plane. The quantum-mechanical evolution of the state vector is calculated exactly and in closed form even though the Hilbert space is infinite dimensional. We also study the autocorrelation function which, as in the work of Milonni, Ackerhalt, and Goggin, is found to decay in the case of quasiperiodic pulsing that may possibly be associated with a manifestation of chaos in a quantum-mechanical system.

On an optical realization of the SU (1,1) geometric phase, and the Bolyai-Lobachevsky plane

Cs. Benedek, M. G. Benedict

We introduce and analyze the SU (1,1) geometric phase emerging in a series of discrete transformations in an optical ring cavity containing partial reflectors. In the theoretical description the underlying projective space is the Bolyai-Lobachevsky (B-L) plane. We show that the resulting geometric phase is equal to half of the area of an object on this plane, determined by the experimental parameters. In the case of three transformations this object is a triangle, and its sides and angles can be related to the reflection and transmission coefficients of the applied mirrors.
