Ionization by few-cycle pulses: Tracing the electron orbits RID A-7617-2010
(American Physical Society, 2005)
High-order above-threshold ionization by few-cycle laser pulses is analyzed in terms of quantum orbits. For a given carrier-envelope phase, the number of contributing orbits and their ionization and rescattering times ...
Finite-Hilbert-basis-set calculations for the angular distribution of ionized electrons produced in p+H impact at 20 keV
(American Physical Society, 2004)
We present a different method of extracting the angular distribution of ejected electrons in an ion-atom collision from a two-centered finite Hilbert basis-set calculation. We obtain good agreement with experiment for a ...
Quantum lithography with classical light: Generation of arbitrary patterns
(American Physical Society, 2007)
Based on our previous scheme [Hemmer , Phys. Rev. Lett. 96, 163603 (2006)] we show the procedures to obtain any one- or two-dimensional pattern by multiple exposures. A key modification to the resonance condition is made ...
Optical imaging of phonological processing in two distinct orthographies
(2008)
Recent fMRI studies comparing the processing of alphabetic versus logographic scripts provide evidence for shared and orthography-speciWc regions of neural activity. The present study used near-infrared spectroscopy to ...
Laughter and humour
(Oxford University Press, 2001)
This is an overview of theories of humor's adaptive significance.
Buffer-gas-induced absorption resonances in Rb vapor RID B-9041-2008
(American Physical Society, 2004)
We observe transformation of the electromagnetically induced transparency (EIT) resonance into an absorption resonance in a Lambda interaction configuration in a cell filled with Rb-87 and a buffer gas. This transformation ...
Atom microscopy via two-photon spontaneous emission spectroscopy RID A-5077-2009
(American Physical Society, 2009)
We study subwavelength position measurement via spontaneous emission spectroscopy with two photons. Our model systems are a single Lambda-type three-level atom, in which a dual interaction generates two independent photons, ...
Continuous-variable entanglement in a correlated spontaneous emission laser
(American Physical Society, 2005)
We discuss the generation and evolution of entangled light in a correlated spontaneous emission laser. The master equation for the two-mode field in a cavity is derived and solved analytically. The time-dependent characteristic ...
Disentanglement in a two-qubit system subjected to dissipation environments RID A-4660-2010
(American Physical Society, 2007)
We investigate the time evolution of entanglement of various entangled states of a two-qubit system exposed to either thermal or squeezed reservoirs. We show that, except for the vacuum reservoir, the sudden-death of ...
Electromagnetically induced transparency in rubidium vapor prepared by a comb of short optical pulses
(American Physical Society, 2005)
It was shown by Kocharovskaya and Khanin [Sov. Phys. JETP 63, 945 (1986)] that a comb of optical pulses can induce a ground-state atomic coherence and change the optical response of an atomic medium. In our experiment, we ...
