Non-sequential double ionization below laser-intensity threshold: Anticorrelation of electrons without excitation of parent ion
D. I. Bondar, G. L. Yudin, W. -K. Liu +2
Two-electron correlated spectra of non-sequential double ionization below laser-intensity threshold are known to exhibit back-to-back scattering of the electrons, viz., the anticor…
Herschel-HIFI observations of high-J CO lines in the NGC 1333 low-mass star-forming region
U. A. Yıldız, E. F. van Dishoeck, L. E. Kristensen +60
Herschel-HIFI observations of high-J lines (up to J_u=10) of 12CO, 13CO and C18O are presented toward three deeply embedded low-mass protostars, NGC 1333 IRAS 2A, IRAS 4A, and IRAS…
The 3D transport diagram of a triple quantum dot
G. Granger, L. Gaudreau, A. Kam +5
We measure a triple quantum dot in the regime where three addition lines, corresponding to the addition of an electron to each of three dots, pass through each other. In particular…
Enhancement and suppression of tunneling by controlling symmetries of a potential barrier
Denys I. Bondar, Wing-Ki Liu, Misha Yu. Ivanov
We present a class of 2D systems which shows a counterintuitive property that contradicts a semi classical intuition: A 2D quantum particle "prefers" tunneling through a barrier ra…
From Frequency to Meaning: Vector Space Models of Semantics
Peter D. Turney, Patrick Pantel
Computers understand very little of the meaning of human language. This profoundly limits our ability to give instructions to computers, the ability of computers to explain their a…
