Quantal-Classical Correspondence Impulse Theory

Physical Review Letters, 2000
The quantal impulse cross section is derived in a novel form appropriate for direct classical correspondence. The classical impulse cross section is then uniquely defined and yields the first general classical expression for nl-n(')l(') collisional transitions. The derived cross sections satisfy the optical theorem and detailed balance.

Decoherence, Orbit, and Classical Linear Frequency Entropy: Quantum-Classical Correspondence

Communications in Theoretical Physics, 2009
Summary: The decoherence process is analyzed for an open quantum system that is classically chaotic, with a classical linear frequency entropy developed to measure the stability of classical motion. Investigation shows that the decoherence measured by the rate of quantum linear entropy production varies significantly with both the underlying classical ...
