Quantum Chessboards in the Deuterium Molecular Ion
نویسنده
چکیده
We present a new algorithm for vibrational control in deuterium molecules that is feasible with current experimental technology. A pump mechanism is used to create a coherent superposition of the D2 vibrations. A short, intense infrared control pulse is applied after a chosen delay time to create selective interferences. A ‘chessboard’ pattern of states can be realized in which a set of evenor odd-numbered vibrational states can be selectively annihilated or enhanced. A technique is proposed for experimental realization and observation of this effect using 5 fs pulses of λ = 790 nm radiation, with intermediate intensity (5× 10 W cm−2).

Quantum Chessboards in Deuterium Wavepackets
We present a novel scheme for quantum manipulation in ultrafast diatomic molecules. A pump mechanism is used to create a coherent superposition of the D + 2 vibrations. A short, intense, control pulse is applied, after a fractional coherence time, to create selective interferences. A 'chessboard' pattern of states can be realised in which the set of even/odd numbered vibrational states can be a...
متن کاملDEUTERIUM STUDIES IN THE DISPROPORTIONATION OF THIOXANTHYLIUM SALTS
Deuterium labelling is used to show that the disproportionation of thioxanthylium salts involve transfer of a hydride, (deuteride) ion from the9-positionof one molecule of the compound, as its hydro], to the 9 - position of another molecule in the cation form
متن کاملPhoto double ionization of molecular deuterium
A helium-like description of photo double ionization of molecular deuterium is extended to derive a dependence of molecular excitation amplitudes on electron energy sharing and dynamical quantum numbers labelling internal modes of excitation of the escaping electron pair. Both linear and circular polarizations are considered, and predictions regarding circular dichroisms in the angular distribu...
متن کاملMolecular-Atomic Transition along the Deuterium Hugoniot Curve with Coupled Electron-Ion Monte Carlo Simulations.
We have performed simulations of the principal deuterium Hugoniot curve using coupled electron-ion Monte Carlo calculations. Using highly accurate quantum Monte Carlo methods for the electrons, we study the region of maximum compression along the Hugoniot, where the system undergoes a continuous transition from a molecular fluid to a monatomic fluid. We include all relevant physical corrections...
متن کاملDynamical evolution of nonclassical properties in cavity quantum electrodynamics with a single trapped ion
In this paper, by considering a system consisting of a single two-level trapped ion interacting with a single-mode quantized radiation field inside a lossless cavity, the temporal evolution of the ionic and the cavity-field quantum statistical properties including photon-counting statistics, quantum fluctuations of the field quadratures and quantum fluctuations of the ionic dipole variables are...
