Sentences with phrase «state of single atoms»

Here, the ability to control the state of single atoms is decisive.

Not exact matches

Each hydrogen atom, made up of just a single proton and electron, can be found in two slightly different states: a higher energy state in which the electron and proton essentially spin in the same direction, and a lower energy state in which they spin in opposite directions.

Professor Truscott's team first trapped a collection of helium atoms in a suspended state known as a Bose - Einstein condensate, and then ejected them until there was only a single atom left.

He predicted a «superradiant» state, where, when large numbers of photons or quanta are put into a system with many atoms, the decay becomes much faster than for a single atom in isolation.

Researchers at Washington State University have used a super-cold cloud of atoms that behaves like a single atom to see a phenomenon predicted 60 years ago and witnessed only once since.

For the study, published in the journal Nature Physics, the Kaiserslautern team around Professor Widera (Department of Physics and State Research Center OPTIMAS) developed a novel model system: A single atom is cooled by lasers near to absolute zero temperature and trapped by light within a near - perfect vacuum.

In 1995 her colleagues showed that thousands of cold subatomic particles can behave like a single enormous atom, a state called a Bose - Einstein condensate.

The term state is in quotes, because a wide variety of agents — ranging from single atoms such as xenon to polycyclic hydrocarbons — can produce insensibility to pain and loss of awareness.

For the first time, the Penn State researchers grew a single atomic layer of tungsten diselenide on a one - atom - thick substrate of graphene with pristine interfaces between the two layers.

«Our state - of - art transmission electron microscope is a unique tool to see extremely tiny features, such as single atoms,» said Sooyeon Hwang, a scientist at CFN and a co-author on the paper.

Superinsulation thus joins the ranks of other bizarre phases of matter that exist under extreme conditions, like superconductivity and Bose - Einstein Condensate (a condition in which, at almost absolute zero, large groups of atoms blur together into a single quantum state).

But thanks to an eerie quantum effect known as superposition — which allows an atom, electron or other particle to exist in two or more states, such as «spinning» in opposite directions at once — a single qubit made of a particle in superposition can simultaneously encompass both digits.

But the large size difference between the tip and the sample causes resolution difficulties — if we were to imagine that a single atom was the same size as a head of a pin, then the tip of the microscope would be as large as the Empire State Building.

Quantum dots are tiny structures, measuring no more than a few nanometres across, which due to quantum confinement can only assume certain, discrete states comparable to the energy level of a single atom.

The researchers used a technique called inelastic electron tunneling spectroscopy to probe the quantum spin states of a single cobalt atom bound to an MgO layer.

The issue first raised its head in 2015, when a team led by Edmund Myers at Florida State University measured the difference in masses of the nucleus of a helium - 3 atom and a deuteron — the nucleus of a deuterium or heavy hydrogen atom — with a single proton bound to...

As hydrogen atoms move about in space, they can absorb small amounts of energy, sending the atom's single electron to a higher energy state.
