Robust Entanglement in Atomic Systems via Lambda-Type Processes [PDF]
, 2002 It is shown that the system of two three-level atoms in $\Lambda$ configuration in a cavity can evolve to a long-lived maximum entangled state if the Stokes photons vanish from the cavity by means of either leakage or damping. The difference in evolution

The broad line region of AGN: Kinematics and physics [PDF]
Serbian Astronomical Journal, 2006 In this paper a discussion of kinematics and physics of the Broad Line Region (BLR) is given. The possible physical conditions in the BLR and problems in determination of the physical parameters (electron temperature and density) are considered. Moreover,

Ionization of Hydrogen in the Solar Atmosphere
Journal of Astronomy and Space Sciences, 2021 The ionization degree of hydrogen is crucial in the physics of the plasma in the solar chromosphere. It specifically limits the range of plasma temperatures that can be determined from the Hα line.

Stark Broadening of Zn III Spectral Lines
Universe, 2022 Stark widths for spectral lines within 24 multiplets of Zn III singlets and triplets have been calculated using modified semiempirical method for an electron density of 1017 cm−3 and temperatures from 5000 K up to 100,000 K.

Bound States and Scattering Processes in the ^4He_3 Atomic System [PDF]
, 1997 We present a mathematically rigorous method for solving three-atomic bound state and scattering problems. The method is well suited for applications in systems where the inter-atomic interaction is of a hard-core nature.

A Process Calculus of Atomic Commit
Electronic Notes in Theoretical Computer Science, 2004 AbstractThis article points out a strong connection between process calculi and atomic commit. Process calculus rendezvous is an abstract semantics for atomic commitment. An implementation of process-calculus rendezvous is an atomic commit protocol. Thus, the traditional correctness properties for atomic commit are entailed by a bisimulation proof of a

Oxygen Transfer on Substituted ZrO2, Bi2O3, and CeO2 Electrolytes with Platinum Electrodes II. A-C Impedance Study [PDF]
, 1983 An equivalent electrical circuit that describes the electrode processes on different electrolytes, using porous Pt electrodes,is given. Diffusional processes are important and have to be presented by Warburg components in the circuit.

Signal tracking beyond the time resolution of an atomic sensor by Kalman filtering [PDF]
, 1998 We study causal waveform estimation (tracking) of time-varying signals in a paradigmatic atomic sensor, an alkali vapor monitored by Faraday rotation probing.
