A whirlpool of hybrid light-matter particles called polaritons has been created using a spiral laser beam.

Polaritons are hybrid particles that have properties of both matter and light. The ability to control polariton flows in this way could aid the development of completely novel technology to link conventional electronics with new laser and fibre-based technologies.

Polaritons form in semiconductors when laser light interacts with electrons and holes (positively charged vacancies) so strongly that it is no longer possible to distinguish light from matter.

When two
giant LIGO detectors
are switched on in the US next year, they will help scientists pick up the faint ripples of black hole collisions millions of years ago, known as gravitational waves. 

Black holes cannot be seen, but scientists hope the revamped detectors, which act like giant microphones, will find remnants of black hole collisions - and theoretical physicists hope experimentalists will give validation for their numerical model.

I am quite happy to report today that the CMS experiment at the CERN Large Hadron Collider has just published a new search which fills a gap in studies of extended Higgs boson sectors. It is a search for the decay of the A boson into Zh pairs, where the Z in turn decays to an electron-positron or a muon-antimuon pair, and the h is assumed to be the 125 GeV Higgs and is sought for in its decay to b-quark pairs. 

If you are short of time, this is the bottomline: no A boson is found in Run 1 CMS data, and limits are set in the parameter space of the relevant theories. But if you have a bit more time to spend here, let's start with the beginning - What's the A boson, you might wonder for a start. 
If the distribution of dark matter in the region near Earth is lower than it is usually assumed then the interpretation of null results of direct detection efforts must be reconsidered. Astrophysicists have been searching for hard evidence of dark matter for decades.  The most favored model has been that dark matter consist  weakly interacting massive particles or WIMPS.  The basic assumption has been that dark matter is more or less evenly spread through the galaxy with no large scale variations.  The work of C.

I am using my blog to advertise the opening of PhD positions in Padova University, to work at several research projects and obtain a PhD in Physics. These are offered to Chinese students through the China Scolarship Council. More information is available at this link.
If you are a bright Chinese student who speaks at least some English and is willing to spend three years working in data analysis for Higgs physics in the CMS experiment, I will take you - so what are you waiting for ? Applications close soon!

Below is a table with deadlines and information.

Relativistic quantum field theory does not apply to everyday life.  It doesn't apply to one beam circling the Large Hadron Collider (LHC).  When two beams traveling in opposite directions smash together, that is when the crazy magic of relativistic quantum field theory dominates.  In order to calculate the odds of scattering events, the sum of all possible histories must be accounted for.

SLAC National Accelerator Laboratory at Stanford

By Ian Bailey, Lancaster University

Scientists working on an experiment at the SLAC National Accelerator Laboratory in the US have taken a step forward in developing a technology which could significantly reduce the size of particle accelerators. The technology is able to accelerate particles more rapidly than conventional accelerators at a much smaller size.

Last year, two experiments at the Large Hadron Collider announced the finding of a new elementary particle - the long-theorized Higgs particle. 

Many calculations indicate that the particle discovered last year in the CERN particle accelerator was indeed the famous Higgs particle. Physicists agree that the CERN experiments did find a new particle that had never been seen before, but an international team say they are not convinced it was the Higgs particle. 

Maybe it just looks like it. And maybe it is not alone. 

The research team analyzed the existing scientific data from the LHC and published an analysis in Physical Review D

Since 1999, a conjecture by Asher Peres, the 'inventor' of quantum teleportation, that the weakest form of quantum entanglement can never result in the strongest manifestation of the phenomenon, has been debated. 

Peres thought about the phenomenon of quantum entanglement and its different manifestations. When two objects (take photons, for example) are entangled, they remain correlated regardless of the distance that separates them physically: whether they are separated by a millimeter or by several kilometers, any action done to one of them will immediately affect the other. To check whether a system is entangled, scientists test for Bell's inequality.
