X Rays Atom Iron Tunneling Atoms X Ray
- Atoms may not have bones, but we still want to know how they are put together. These tiny particles are the basis on which all normal matter is built (including our bones), and understanding them helps us understand the larger Universe. We currently use high-energy X-ray light to help us understand atoms and molecules and how they're arranged, catching diffracted beams to reconstruct their configurations in crystal form. Now, scientists have used X-rays to characterize the properties of a ... [Read More]

- Microsoft's Quantum Breakthrough – Were They Wrong? In March 2022, Microsoft announced research findings concerning the manifestation of a unique particle that could potentially be utilized for crafting notably durable quantum bits. However, University of Basel's researchers are currently questioning these conclusions regarding the so-called Majorana particles. They've carried out computations that indicate that the results can be explained differently. In 1938, a brilliant mind ... [Read More]

Tantalum Materials Princeton University Qubits Quantum Scientists
- Whether it's baking a cake, building a house, or developing a quantum device, the quality of the end product significantly depends on its ingredients or base materials. Researchers working to improve the performance of superconducting qubits, the foundation of quantum computers, have been experimenting using different base materials in an effort to increase the coherent lifetimes of qubits. The coherence time is a measure of how long a qubit retains quantum information, and thus a primary ... [Read More]

Atom Argonne National Laboratory Electron Ohio University Model Electrons
- SX-STM enables detection of atom type, simultaneous measurement of its chemical state. Atomic-scale imaging emerged in the mid-1950s and has been advancing rapidly ever since—so much so, that back  in 2008 , physicists successfully used an electron microscope to image a single hydrogen atom. Five years later , scientists were able to peer inside a hydrogen atom using a " quantum microscope ," resulting in the first direct observation of electron orbitals. And now we have the first ...

Neutron Stars Reaction Nuclei Neutron Stars Star
- A nuclear reaction experiment provides a glimpse at what is going on when neutron stars consume nearby companion stars. Neutron stars are among the densest objects in the universe, reaching several times the mass of our Sun, but little more than 20 kilometres in diameter. One teaspoon of a neutron star's material would weigh as much as a mountain. Their immense gravitational pull will suck in material from other cosmic objects that venture too close. This process can strip hydrogen and helium ... [Read More]

Symmetry Crystal Excitation Atoms Phonons Phonon
- Atoms in a crystal form a regular lattice, in which they can move over small distances from their equilibrium positions. Such phonon excitations are represented by quantum states. A superposition of phonon states defines a so-called phonon wavepacket, which is connected with collective coherent oscillations of the atoms in the crystal. Coherent phonons can be generated by excitation of the crystal with a femtosecond light pulse, and their motions in space and time can be followed by scattering ... [Read More]


Universe Parity Something University Violation Data
- Physicists have long puzzled over why there is more matter in the Universe than its flipped twin, antimatter . Without this imbalance, the two types of material would have canceled out , leaving nothing but a boring glow in the vast emptiness of space. Somehow, at some point, something changed in the way the Universe works on a fundamental level, favoring the mirrored state – or parity – of one kind of 'stuff' over the other. Scientists have sought clues to this critical moment in ... [Read More]

Their new technique generates high resolution X-ray images of dried biological material that has not been frozen, coated, or otherwise altered beforehand—all with little ... [Read More]


Higgs Boson Decay Higgs Particles Model Standard Model
- For the first time since the discovery of the Higgs boson made international headlines in 2012, physicists have witnessed the Higgs boson decay into a Z boson and a photon. The observations, part of the ATLAS and CMS experiments at CERN 's Large Hadron Collider (LHC) on the French-Swiss border, may provide indirect evidence for particles beyond those predicted by the Standard Model of particle physics. Higgs bosons are the quantum excitation of the Higgs field which interacts with other ... [Read More]

The ... [Read More]


Energy Quantum Bob State Quantum Energy Hotta
- For their latest magic trick, physicists have done the quantum equivalent of conjuring energy out of thin air. It's a feat that seems to fly in the face of physical law and common sense. "You can't extract energy directly from the vacuum because there's nothing there to give," said William Unruh , a theoretical physicist at the University of British Columbia, describing the standard way of thinking. Original story reprinted with permission from Quanta Magazine , an editorially independent ... [Read More]

- What happens if dark-matter particles are produced inside a jet of Standard-Model particles? This leads to a novel detector signature known as semi-visible jets! The ATLAS Collaboration has come up with the first search for semi-visible jets, looking for them in a general production mode where two protons interact by exchanging an intermediate particle, which is then converted into two jets. The elusive nature of dark matter remains one of the biggest mysteries in particle physics. Most of the ... [Read More]
