This boosts the energy level of
electron pairs on the island, causing them to break their superconducting bond to one another and hop to a nearby probe, which then channels them to a detector.
Not exact matches
An ionized hydrogen atom, consisting of a proton shorn of its associated
electron, can not undergo the 21 - centimeter transition discussed above, since that transition depends
on the relative spins of the
electron - proton
pair.
How far it goes in depends
on the nature of the
electron pairing, and changes as the material is cooled down further and further.
Depending
on its nature, dark matter annihilation could sometimes yield detectable particles and antiparticles, such as
electrons and positrons, or
pairs of photons.
When atoms come together to form molecules,
electrons on different atoms
pair up to form bonds that lock the molecule together.
Superconductivity is characterised by the way the
electrons interact: within a superconductor
electrons form
pairs, and the spin alignment between the
electrons of a
pair may be different depending
on the type — or «symmetry» — of superconductivity involved.
Superconductivity is based
on the fact that in certain materials
electrons can
pair up which — at a higher temperature — would otherwise repel each other.
When light shines
on a semiconducting material such as TiO2, it generates either free negative (
electrons) and positive (holes) charges or a bound neutral
electron - hole
pair, called an exciton.
Yi's work focuses
on hightemperature superconductivity, a phenomenon in which
electrons coherently
pair up to travel without resistance in a material at a relatively high temperature.
Hopes for building a working quantum computer hinge
on physicists» ability to intertwine
electrons into
pairs such that changes made to one instantly affect its partner — a process called entanglement.
Superconductivity relies
on delicate couples of
electrons known as Cooper
pairs, which are disappointingly easy to break apart by magnetic fields.
The ideas they worked
on together are now known as BCS theory and provide a description of the superconducting state in terms of interactions between
pairs of
electrons.
In a 2014 paper in Nature, they concluded that atomic vibrations in the STO travel up into the iron selenide and give
electrons the additional energy they need to
pair up and carry electricity with zero loss at higher temperatures than they would
on their own.
The depth in which it goes depends
on the
paired electrons and changes that take place as the material gets cooler.
By extending the coherence time of
electron states to over half a second, a team of scientists from Berkeley Lab, UC Berkeley, and Harvard University has vastly improved the performance of one of the most potent possible sensors of magnetic fields
on the nanoscale — a diamond defect no bigger than a
pair of atoms, called a nitrogen vacancy (NV) center.
There are two main theoretical models, one based
on small magnetite particles that may reorient in an external magnetic field and the other based
on the idea that upon photo excitation a certain type of molecules in the eye of a bird support a radical
pair formed by two
electrons which evolve under the joint action of the Zeeman interaction with the external magnetic field and the hyperfine interaction with the supporting molecule.
This discovery not only shows the profound effects of pressure
on magnetism, it also discloses, for the first time, that pressure induced a spin -
pairing transition in magnetite that results in changes in the
electron mobility and structure.
