Effect of polariton-polariton interactions on the excitation spectrum of a non-equilibrium condensate in a periodic potential
D. N. Krizhanovskii, E. A. Cerda, S. S. Gavrilov +9
Polariton condensates are investigated in periodical potentials created by surface acoustic waves using both resonant and non-resonant optical excitation. Under resonant pumping co…
Multi-channel search for squarks and gluinos in sqrt(s)=7 TeV pp collisions with the ATLAS detector
ATLAS Collaboration
A search for supersymmetric particles in final states with zero, one, and two leptons, with and without jets identified as originating from b-quarks, in 4.7 fb-1 of sqrt(s)=7 TeV p…
Poisson spectra in polynomial algebras
David A. Jordan, Sei-Qwon Oh
A significant class of Poisson brackets on the polynomial algebra $\C[x_1,x_2,..., x_n]$ is studied and, for this class of Poisson brackets, the Poisson prime ideals and Poisson pr…
Poisson brackets and Poisson spectra in polynomial algebras
David A. Jordan, Sei-Qwon Oh
Poisson brackets on the polynomial algebra C[x,y,z] are studied. A description of all such brackets is given and, for a significant class of Poisson brackets, the Poisson prime ide…
On the Origin of Mass Segregation in NGC 3603
Xiaoying Pang, Eva K. Grebel, Richard J. Allison +5
We present deep Hubble Space Telescope/Wide Field and Planetary Camera 2 photometry of the young HD 97950 star cluster in the giant H {\sc ii} region NGC 3603. The data were obtain…
Characterizations of left orders in left Artinian rings
V. V. Bavula
Small (1966), Robson (1967), Tachikawa (1971) and Hajarnavis (1972) have given different criteria for a ring to have a left Artinian left quotient ring. In this paper, three more n…
