Landau singularities revisited

Landau singularities revisited

MathematicsParticle physicsPhysics

By César Tomé

Scientists have used computational algebraic geometry to study predictions for particle physics experiments, such as those at the Large Hadron Collider (LHC). These experiments, in combination with new mathematical tools, help to solve unanswered questions in physics in a much faster way and have a profound impact on our understanding of nature. When studying particle […]

New multispecies compact ion source and efficient experimental proton beam characterization

New multispecies compact ion source and efficient experimental proton beam characterization

Physics

By Invited Researcher

Any particle accelerator needs a reliable electron or ion source as a first, humble but essential and critical component. The world’s most powerful particle accelerator today -the Large Hadron Collider- extracts its protons from a single bottle of Hydrogen gas. Ion sources produce beams for a large variety of different scientific experiments, industrial processes and […]

How logic alone may prove that time doesn’t exist

How logic alone may prove that time doesn’t exist

Philosophy of sciencePhysics

By Invited Researcher

Modern physics suggests time may be an illusion. Einstein’s theory of relativity, for example, suggests the universe is a static, four-dimensional block that contains all of space and time simultaneously – with no special “now”. What’s the future to one observer, is the past to another. That means time doesn’t flow from past to future […]

DIPC Quantum SystemsPhysics

By DIPC

Numerous physical systems—from classical electromagnetic fields to quantum particle fields—exhibit oscillating wave behavior. Specific settings exist, both in nature and in artificial systems, where these waves form patterns with holes, loops, and other distinct topological characteristics, often referred to as topological wave structures. Now, a team of researchers describes how these structures, which have previously […]

Superconductors can carry large electrical currents without any resistance. One situation where they don’t carry currents without resistance is when there is too much current. By designing microscopic electronic components made from very thin superconductors, researchers can use this effect to create a switch, like a transistor. Nanowire superconducting switching devices (called nanocryotrons, or nTrons […]

Searching for the decay of nature’s rarest isotope: Tantalum-180m

Searching for the decay of nature’s rarest isotope: Tantalum-180m

Particle physicsPhysics

By César Tomé

Tantalum is one of the rarest elements and has multiple stable isotopes. The least abundant tantalum isotope, Ta-180 is found naturally in a long-lived excited state, a feature unique to this isotope. In excited states, a nuclei’s protons or neutrons have higher than normal energy levels. Although energetically possible, the radioactive decay of this excited […]

Computer scienceMaterialsPhysics

By César Tomé

Atomic force microscopy, or AFM, is a widely used technique that can quantitatively map material surfaces in three dimensions, but its accuracy is limited by the size of the microscope’s probe. A new AI technique overcomes this limitation and allows microscopes to resolve material features smaller than the probe’s tip. A new deep learning algorithm […]

Particle physicsPhysics

By César Tomé

A new analysis by the STAR collaboration at the Relativistic Heavy Ion Collider (RHIC), a particle collider at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory, provides the first direct evidence of the imprint left by what may be the universe’s most powerful magnetic fields on “deconfined” nuclear matter . The evidence comes from […]
