Researchers directly simulate the fusion of oxygen and carbon nuclei

The fusion of two nuclei is a complex process influenced by many factors. These factors include not only the relative energy and angular momentum of the two nuclei, but also how their structures evolve as they collide. The outcome of the collisions is dramatically impacted by the quantum nature of the nuclei. The best way […]

Observing how light makes a metal—new details about the insulator-to-metal transition in a quantum material

With just the flick of a switch, quantum materials can undergo drastic changes. One notable example is the insulator-to-metal transition, a reversible physical phenomenon in which a material shifts from an insulating state, which will not conduct electricity, to a metallic one that will.

Physicists observe excited states in lanthanum-120

For the first time, physicists have observed excited states in the very neutron-deficient odd-odd nucleus, lanthanum-120. The study, published in Physics Letters B, was conducted by researchers from the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences, and their collaborators from France, Finland, South Africa and other countries.

Exploring three-dimensional quantum Griffiths singularity in bulk unconventional iron-based superconductors

Exploration of exotic quantum phase transitions has always been a focus in condensed matter physics. Critical phenomena in a phase transition are entirely determined by the universality class, which is controlled by the spatial and/or order-parameters and is independent of microscopic details.

What flavor is that neutrino? Adding flavor helps to track neutrino movement in astrophysical systems

Neutrinos have a quantum mechanical property called “flavor.” This flavor can transform as neutrinos move through space. A major challenge is to keep track of both the physical movement of the neutrinos and their change of flavor in astrophysical systems such as core-collapse supernovae and neutron star mergers. The complicated arrangement and large number of […]

Neural networks made of light can make machine learning more sustainable

Scientists propose a new way of implementing a neural network with an optical system which could make machine learning more sustainable in the future. The researchers at the Max Planck Institute for the Science of Light have published their new method in Nature Physics, demonstrating a method that is much simpler than previous approaches.

Securely propagating entanglement at the push of a button

Entanglement, Einstein’s “spooky action at a distance,” today is THE tool of quantum information science. It is the essential resource for quantum computers and used to transmit quantum information in a future quantum network. But it is highly sensitive. It is therefore an enormous challenge to entangle resting quantum bits (qubits) with flying qubits in […]

Belle II experiment reports the first direct measurement of tau-to-light-lepton ratio

The Belle II experiment is a large research effort aimed at precisely measuring weak-interaction parameters, studying exotic hadrons (i.e., a class of subatomic particles) and searching for new physical phenomena. This effort primarily relies on the analysis of data collected by the Belle II detector (i.e., a general purpose spectrometer) and delivered by the SuperKEKB, […]

Neutrons are a hot new way to measure the temperature of electronic components

From LEDs to batteries, our lives are full of electronics, and there is a constant push to make them more efficient and reliable. But as components become increasingly sophisticated, getting reliable temperature measurements of specific elements inside an object can be a challenge.

Oxygen tweaking may be key to accelerator optimization

Particle accelerators are pricey, but their cost comes with good reason: These one-of-a-kind, state-of-the-art machines are intricately designed and constructed to help us solve mysteries about what makes up our universe. Still, the scientists and engineers building these machines must do their best to save where they can. Researchers at the U.S. Department of Energy’s […]

Observation of 3D acoustic quantum Hall states

The quantum Hall effect (QHE) is one of the most notable discoveries in condensed matter physics, opening the door to topological physics. Extending QHE into three dimensions is an inspiring but challenging endeavor. This difficulty arises because the Landau levels in three dimensions extend into bands along the direction of the magnetic field, preventing the […]

New experiment investigates light-induced Meissner effect in optically driven superconductor

Superconductivity is a fascinating phenomenon, which allows a material to sustain an electrical current without any loss. This collective quantum behavior of matter only appears in certain conductors at temperatures far below ambient.

Physicists discover a way to imprint a previously unseen geometrical form of chirality onto electrons

Have you ever placed the palm of your left hand on the back of your right hand in such a way that all fingers point in the same direction? If you have, then you probably know that your left thumb will not touch its right counterpart. Neither rotations nor translations nor their combinations can turn […]
