Sentences with phrase «scalar field»

A scalar field refers to a concept in mathematics and physics. It represents a quantity that changes at different points in space. Think of it as a field where every point in space has a specific value associated with it. This value is a scalar, which means it has magnitude but no direction. Examples of scalar fields include temperature, pressure, and density. Full definition
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.»
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.

As an application of our method, we examine thermal phase mixing in the context of Ginzburg - Landau models with short - range interac... ▽ More We show how to achieve lattice - spacing independent results in numerical simulations of finite - temperature stochastic scalar field theories.
Wilczek, who was not involved in the work, notes that the new scalar field does not help explain where the rest of the energy predicted by the standard model went.
Inflation is driven by a hypothetical scalar field with properties that can be adjusted to effectively produce any outcome.
In fact contributions from scalar fields which are constant in space are usually also included in the cosmological constant.
If the new particle truly is the Higgs, its verification of real scalar fields would be nearly as important as its role in generating mass.

Using simple tools — a pencil, for the most part — her activity excavates a vast scalar field where she discovers, quite to her astonishment, clustered points that form merely to reform.
Since the unified field is so energetic, the new scalar field would be at very small energies.
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.
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.
Scalar fields which do change in space are hard to distinguish from a cosmological constant, because the change may be extremely slow.
That burst of expansion was supposedly caused by a scalar field in space, much like the Higgs field.
One explanation is that dark energy is a scalar field whose properties at every point in space «roll» from one value to another.
Krauss and James Dent of the University of Louisiana at Lafayette, devised a new scalar field that does just that.
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.
If the new scalar field can use the Higgs to link up to this high - energy field, it could acquire some energy of its own.
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.
Under the general theory of relativity, a gravitational field is described by deformations of spacetime, whereas matter is represented as a scalar field (the simplest type of field where every point in space is assigned only one value).
Things took a more interesting turn when physicists looked at excitations in the scalar field, which are interpreted as particles.
Others attribute the Big Bang to what they call «a false vacuum» or «a scalar field» or «vacuum energy» — some quality or thing, at any rate, that introduced a measure of instability into the nothingness that was.
