Sentences with phrase «scalar fields»

I should point out that there are other explanations for scalar fields as well, but string theory does seem to give those naturally to you.

Even before the Higgs was discovered, Krauss was wondering if other scalar fields could couple to the Higgs field, offering links to new physical phenomena.

Then when they did, it hit me that, my God, all of these possibilities that I'd long discounted involving the existence of new scalar fields in the universe might actually be right.»

However, cosmologists soon realised that the dark matter could be made of even more exotic things: supersymmetric particles such as the gravitino or photino, for example, or oscillating scalar fields such as the axion.

Even before the Higgs was discovered, physicist Lawrence Krauss of Arizona State University in Tempe was wondering if other scalar fields existed that could interact with the Higgs field.

While scalar fields are widely used by theorists in contemplating cosmic phenomena, no experiment has been able to detect one.

In fact contributions from scalar fields which are constant in space are usually also included in the cosmological constant.

Scalar fields which do change in space are hard to distinguish from a cosmological constant, because the change may be extremely slow.

Two proposed forms for dark energy are the cosmological constant, a constant energy density filling space homogeneously, and scalar fields such as quintessence or moduli, dynamic fields whose energy density can vary in time and space.

One explanation is that dark energy is a scalar field whose properties at every point in space «roll» from one value to another.

That burst of expansion was supposedly caused by a scalar field in space, much like the Higgs field.

It may even be that «dark energy,» the mysterious force that even now drives the universe to expand at an accelerating rate, is itself a scalar field.

Since the unified field is so energetic, the new scalar field would be at very small energies.

Krauss and James Dent of the University of Louisiana at Lafayette, devised a new scalar field that does just that.

The new scalar field would have zero energy density, but it can use the Higgs to link up to this high - energy field, and in the process it acquires energy of its own (Physical Review Letters, doi.org/ngf).

Theoretical physicist Robert Scherrer of Vanderbilt University in Tennessee posits that dark matter and dark energy are two versions of the same thing, a form of energy known as a scalar field.

Krauss and Dent had devised a new scalar field that would exist outside the standard model.

It's called a scalar field in the jargon and that's precisely the kind of thing you might get from an extra dimension.

Things took a more interesting turn when physicists looked at excitations in the scalar field, which are interpreted as particles.

Unlike other fields in the standard model, the Higgs field is scalar — it does not act in a specific direction.

«We examined the scalar quantum field around a black hole and a compact object and found that around the collapsing object — the black hole, there are no bound states, but around the compact object there are,» explains FedorPopov, a member of staff at MIPT's Laboratory of High Energy Physics.

Discovered last year, the Higgs boson also comes with an associated field but, unlike others of its class, the Higgs field is scalar — it does not act in a specific direction.
