Quantum Information, Irreversibility and State Collapse in Some Microscopic Models of Measurement

S. Mayburov

The quantum measurement problem considered for measuring system (MS) model which consist of measured state S (particle), detector D and information processing device O. For spin ch…

Quantum Zeno effect in the decay onto an unstable level

Michael B. Mensky

Under certain assumptions it is shown that the decay of level 2 of a three-level system onto level 1 is slowed down because of the further decay of level 1 onto level 0. It is argu…

Spectrum of light scattered from a deformed Bose-Einstein condensate

S. Mancini, V. I. Man'ko

The spectrum of light scattered from a Bose-Einstein condensate is studied in the limit of particle-number conservation. To this end, a description in terms of deformed bosons is i…

Zeno effect preventing Rabi transitions onto an unstable energy level

J. Audretsch, M. B. Mensky, A. D. Panov

We consider a driven 2-level system with one level showing spontaneous decay to an otherwise uncoupled third level. Rabi transitions to the unstable level are strongly damped. This…

Steep anomalous dispersion in coherently prepared Rb vapor

A. M. Akulshin S. Barreiro A. Lezama

Steep dispersion of opposite signs in driven degenerate two-level atomic transitions have been predicted and observed on the D2 line of 87Rb in an optically thin vapor cell. The in…

Parametric Self-Oscillation via Resonantly Enhanced Multiwave Mixing

A. S. Zibrov, M. D. Lukin, M. O. Scully

We demonstrate an efficient nonlinear process in which Stokes and anti-Stokes components are generated spontaneously in a Raman-like, near resonant media driven by low power counte…

Enhancement of Magneto-Optic Effects via Large Atomic Coherence

V. A. Sautenkov, M. D. Lukin, C. J. Bednar +4

We utilize the generation of large atomic coherence to enhance the resonant nonlinear magneto-optic effect by several orders of magnitude, thereby eliminating power broadening and…

Probability Distributions and Hilbert Spaces: Quantum and Classical Systems

V. I. Man'ko, G. Marmo

We use the fact that some linear Hamiltonian systems can be considered as ``finite level'' quantum systems, and the description of quantum mechanics in terms of probabilities, to a…

``Classical'' Propagator and Path Integral in the Probability Representation of Quantum Mechanics

Olga Man'ko, V. I. Man'ko

In the probability representation of the standard quantum mechanics, the explicit expression (and its quasiclassical van-Fleck approximation) for the ``classical'' propagator (tran…

Conventional Quantum Mechanics Without Wave Function and Density Matrix

Vladimir I. Man'ko

The tomographic invertable map of the Wigner function onto the positive probability distribution function is studied. Alternatives to the Schrödinger evolution equation and to the…

Quantum phenomenology and the Continuum Problem

O. Yaremchuk

A new approach to quantum mechanics based on independence of the Continuum Hypothesis is proposed. In one-dimensional case, it is shown that the properties of the set of intermedia…

Aharonov-Bohm scattering of charged particles and neutral atoms: the role of absorption

Juergen Audretsch, Vladimir Skarzhinsky

The Aharonov-Bohm scattering of charged particles by the magnetic field of an infinitely long and infinitely thin solenoid (magnetic string) in an absorbing medium is studied. We d…
