Published Charming experiment finds gluon mass in the proton
(via sciencedaily.com) Original source Nuclear physicists may have finally pinpointed where in the proton a large fraction of its mass resides. A recent experiment has revealed the radius of the proton's mass that is generated by the strong force as it glues together the proton's building block quarks.
Published Can a solid be a superfluid? Engineering a novel supersolid state from layered 2D materials
(via sciencedaily.com) Original source Physicists predict that layered electronic 2D semiconductors can host a curious quantum phase of matter called the supersolid. This counterintuitive quantum material simultaneously forms a rigid crystal, and yet at the same time allows particles to flow without friction, with all the particles belong to the same single quantum state.
Published Revolutionary battery technology to boost EV range 10-fold or more
(via sciencedaily.com) A team develops layering-charged, polymer-based stable high-capacity anode material.
Published Highly charged ions melt nano gold nuggets
(via sciencedaily.com) Original source Shooting ions is very different from shooting a gun: By firing highly charged ions onto tiny gold structures, these structures can be modified in technologically interesting ways. Surprisingly, the key is not the force of impact, but the electric charge of the projectiles.
Published Nanophysics: The right twist
(via sciencedaily.com) Stacked layers of ultrathin semiconductor materials feature phenomena that can be exploited for novel applications. Physicists have studied effects that emerge by giving two layers a slight twist.
Published New type of entanglement lets scientists 'see' inside nuclei
(via sciencedaily.com) Nuclear physicists have found a new way to see inside nuclei by tracking interactions between particles of light and gluons. The method relies on harnessing a new type of quantum interference between two dissimilar particles. Tracking how these entangled particles emerge from the interactions lets scientists map out the arrangement of gluons. This approach is unusual for making use of entanglement between dissimilar particles -- something rare in quantum studies.
Published Semiconductor lattice marries electrons and magnetic moments
(via sciencedaily.com) A model system created by stacking a pair of monolayer semiconductors is giving physicists a simpler way to study confounding quantum behavior, from heavy fermions to exotic quantum phase transitions.
Published New invention: The oxygen-ion battery
(via sciencedaily.com) An oxygen-ion-battery has been invented, based on ceramic materials. If it degrades, it can be regenerated, therefore it potentially has an extremely long lifespan. Also, it does not require any rare elements and it is incombustible. For large energy storage systems, this could be an optimal solution.
Published New simulation reveals secrets of exotic form of electrons called polarons
(via sciencedaily.com) Conditions mapped for the first time of polaron characteristics in 2D materials. TACC's Frontera supercomputer generated quantum mechanical calculations on hexagonal boron nitride system of 30,000 atoms.
Published Neutrinos made by a particle collider detected
(via sciencedaily.com) Physicists have detected neutrinos created by a particle collider. The discovery promises to deepen scientists' understanding of the subatomic particles, which were first spotted in 1956 and play a key role in the process that makes stars burn.
Published Visualization of electron dynamics on liquid helium
(via sciencedaily.com) An international team has discovered how electrons can slither rapidly to-and-fro across a quantum surface when driven by external forces. The research has enabled the visualization of the motion of electrons on liquid helium.
Published Imaging the proton with neutrinos
(via sciencedaily.com) The interactions of the quarks and gluons that make up protons and neutrons are so strong that the structure of protons and neutrons is difficult to calculate from theory and must be instead measured experimentally. Neutrino experiments use targets that are nuclei made of many protons and neutrons bound together. This complicates interpreting those measurements to infer proton structure. By scattering neutrinos from the protons that are the nuclei of hydrogen atoms in the MINERvA detector, scientists have provided the first measurements of this structure with neutrinos using unbound protons.
Published 'Y-ball' compound yields quantum secrets
(via sciencedaily.com) Scientists investigating a compound called 'Y-ball' -- which belongs to a mysterious class of 'strange metals' viewed as centrally important to next-generation quantum materials -- have found new ways to probe and understand its behavior.
Published Batteries: Passivation layer mystery solved
(via sciencedaily.com) In our daily lives, lithium-ion batteries have become indispensable. They function only because of a passivation layer that forms during their initial cycle. As researchers found out via simulations, this solid electrolyte interphase develops not directly at the electrode but aggregates in the solution. Their findings allow the optimization of the performance and lifetime of future batteries.
Published Surprise in the quantum world: Disorder leads to ferromagnetic topological insulator
(via sciencedaily.com) Magnetic topological insulators are an exotic class of materials that conduct electrons without any resistance at all and so are regarded as a promising breakthrough in materials science. Researchers have achieved a significant milestone in the pursuit of energy-efficient quantum technologies by designing the ferromagnetic topological insulator MnBi6Te10 from the manganese bismuth telluride family. The amazing thing about this quantum material is that its ferromagnetic properties only occur when some atoms swap places, introducing antisite disorder.
Published High-energy-density, long life-cycle rechargeable lithium metal batteries
(via sciencedaily.com) Research shows promise for developing high-energy-density rechargeable lithium-metal batteries and addressing the electrochemical oxidation instability of ether-based electrolytes.
Published Scientists find a common thread linking subatomic color glass condensate and massive black holes
(via sciencedaily.com) Atomic nuclei accelerated close to the speed of light become dense walls of gluons known as color glass condensate (CGC). Recent analysis shows that CGC shares features with black holes, enormous conglomerates of gravitons that exert gravitational force across the universe. Both gluons in CGC and gravitons in black holes are organized in the most efficient manner possible for each system's energy and size.

(via sciencedaily.com) n a major breakthrough in the fields of nanophotonics and ultrafast optics, a research team has demonstrated the ability to dynamically steer light pulses from conventional, so-called incoherent light sources.
Published First detection of neutrinos made at a particle collider
(via sciencedaily.com) A team including physicists has for the first time detected subatomic particles called neutrinos created by a particle collider, namely at CERN's Large Hadron Collider (LHC). The discovery promises to deepen scientists' understanding of the nature of neutrinos, which are among the most abundant particles in the universe and key to the solution of the question why there is more matter than antimatter.
