  • Higgs Papers Out | Cosmic Variance

    Updated: 2012-08-03 19:44:35
    We were all transfixed by the Higgs seminars on July 4, but the work was nowhere near over for the experimentalists — they had to actually write up papers describing the results. And of course taking the opportunity to do a little more analysis along the way. Now the papers have appeared on the arxiv. [...]

  • Qubits that never interact could exhibit past-future entanglement

    Updated: 2012-07-30 17:10:01
    (Phys.org) -- Typically, for two particles to become entangled, they must first physically interact. Then when the particles are physically separated and still share the same quantum state, they are considered to be entangled. But in a new study, physicists have investigated a new twist on entanglement in which two qubits become entangled with each other even though they never physically interact.

  • A filament of dark matter between two clusters of galaxies: dark matter detected

July 2012, 10:49 We briefly comment on the paper by Dietrich , Werner , Clowe et al . on A filament of dark matter between two clusters of galaxies which is now in press with Nature . The media have it that this may be a direct detection of dark matter . nbsp The abstract of this paper reads It is a firm prediction of the concordance Cold Dark Matter CDM cosmological model that galaxy clusters live at the intersection of large-scale structure filaments . The thread-like structure of this cosmic web has been traced by galaxy redshift surveys for decades . More recently the Warm-Hot Intergalactic Medium WHIM residing in low redshift filaments has been observed in

The meeting of physicists and astronomers covers General Relativity , Gravity and relativistic field theories and is held every three years since 1975 in different cities . It is named after Marcel Grossmann who was a Swiss mathematician and a collaborator of Einstein in his work on general relativity . Following his recent review paper The dark matter crisis : falsification of the current standard model of cosmology Pavel has been invited by Davit Merrit to give a talk in the parallel session EG4 : Self-Gravitating System The session will take place tomorrow afternoon Tuesday , 3rd of July at the AlbaNova

He became very famous for his theory of entropic gravity and was awarded the Spinoza Prize for his work . In his talk , he showed that his approach can not only reproduce the MONDian behavior of the different kinds of galaxies . He even gave an explanation on why the centers of galaxy clusters deviate from the baryonic Tully-Fisher relation by a factor of four . The reason , he says , lies in the distribution of matter .

  • Physicists demonstrate quantum interference between two photons of different frequencies

    Updated: 2012-06-07 14:50:02
    (Phys.org) -- When two photons simultaneously enter two input ports of a beam splitter, their paths interfere destructively, which causes the photons to simultaneously exit the beam splitter through the same output port. Because this quantum interference effect changes the input into a different output, it could have applications in quantum information processing. But whereas the two photons are usually identical in experiments demonstrating this effect, a new study has demonstrated that quantum interference can also occur between two photons with different frequencies, giving researchers an additional degree of control.

  • Does filamentary accretion of dark matter sub-halos naturally produce a VPOS-like structure?

    SciLogs All Blogs Next Does filamentary accretion of dark matter sub-halos naturally produce a VPOS-like structure from Marcel S . Pawlowski 15. May 2012, 10:44 In the previous post we discussed the VPOS , the vast polar structure of satellite objects around the Milky Way . One of the suggested origins within the cosmological cold dark matter paradigm is that the satellites have been preferentially accreted along large , cosmic filaments . These are long , thread-like structures which arise naturally during the formation of structure in the cosmos . The movie below shows how they come : about One work suggesting that filamentary accretion can solve the VPOS-problem is Lovell et al . 2011 Its abstract claims that : All six haloes of the Aquarius simulations possess a population of subhaloes
