Excitation dependence of resonance line self-broadening at different atomic densities
Hebin Li, Vladimir A. Sautenkov, Yuri V. Rostovtsev +1
We study the dipole-dipole spectral broadening of a resonance line at high atomic densities when the self-broadening dominates. The selective reflection spectrum of a weak probe be…
Evolution equation of quantum tomograms for a driven oscillator in the case of the general linear quantization
G. G. Amosov, V. I. Man'ko, Yu. N. Orlov
The symlectic quantum tomography for the general linear quantization is introduced. Using the approach based upon the Wigner function techniques the evolution equation of quantum t…
Quantum Information and Wave function Collapse
S. Mayburov
Inofrmation-theoretical restrictions on information transferred in the measurement of object S by information system O are studied. It is shown that such constraints, induced by He…
Semigroup of positive maps for qudit states and entanglement in tomographic probability representation
V. I. Man'ko, G. Marmo, A. Simoni +1
Stochastic and bistochastic matrices providing positive maps for spin states (for qudits) are shown to form semigroups with dense intersection with the Lie groups $IGL(n, \mathbb{R…
Centrifugal quantum states of neutrons
V. V. Nesvizhevsky, A. K. Petukhov, K. V. Protasov +1
We propose a method for observation of the quasi-stationary states of neutrons, localized near the curved mirror surface. The bounding effective well is formed by the centrifugal p…
Quasiperiodic propagation in time of some classical/quantum systems: Nielsen's conserved quantity and Floquet properties
Peter Kramer, Tobias Kramer, Vladimir I. Man'ko
We consider classical and quantum propagators for two different time intervals. If these propagators follow one another in a Fibonacci sequence we get a discrete quasiperiodic syst…
Observation of narrow Autler-Townes components in the resonant response of a dense atomic gas
Vladimir A. Sautenkov, Yuri V. Rostovtsev, Eric R. Eliel
We have experimentally studied the reflection of a weak probe beam from a dense atomic potassium vapor in the presence of a strong laser field tuned to the atomic resonance transit…
Intensity correlations in resonance nonlinear magneto-optical rotation
Tigran S. Varzhapetyan, Hebin Li, Gombojav O. Ariunbold +3
We have studied the intensity correlations between two orthogonally linearly polarized components of a laser field propagating through a resonant atomic medium. These experiments h…
Optical imaging beyond the diffraction limit via dark states
Hebin Li, Vladimir A. Sautenkov, Michael M. Kash +5
We study the possibility of creating spatial patterns having subwavelength size by using the so-called dark states formed by the interaction between atoms and optical fields. These…
Symplectic tomography of ultracold gases in tight-waveguides
A. del Campo, V. I. Man'ko, G. Marmo
The phase space is the natural ground to smoothly extrapolate between local and non-local correlation functions. With this objective, we introduce the symplectic tomography of many…
A Lossy Bosonic Quantum Channel with Non-Markovian Memory
O. V. Pilyavets, V. G. Zborovskii, S. Mancini
We provide a simple and realistic model to study memory effects in a lossy bosonic quantum channel over arbitrary number of uses. The noise correlation among different uses is intr…
Detection of Spiral photons in Quantum Optics
V. V. Klimov, D. Bloch, M. Ducloy +1
We show that a new type of photon detector, sensitive to the gradients of electromagnetic fields, should be a useful tool to characterize the quantum properties of spatially-depend…
Frame transforms, star products and quantum mechanics on phase space
P. Aniello, V. I. Man'ko, G. Marmo
Using the notions of frame transform and of square integrable projective representation of a locally compact group , we introduce a class of isometries (tight frame transforms)…
