New Nanoscale Technique Unlocks Quantum Material Secrets

Can Electricity Flow Without Electrons?

Scientists have long held that electricity is carried by individual electrons with discrete charges moving in a metal, even in the case of electrons clumped into quasiparticles. However, "strange metals" fail to obey this paradigm. Researchers have observed a radical quantum blurring of electrons in strange metal into a featureless liquid, potentially pointing toward a new theory of electrical transport.

Testing the Possible Doubly Magic Nature of Tin-100, Researchers Study the Electromagnetic Properties of Indium Isotopes

Atomic nuclei with "magic numbers" of protons or neutrons in their nuclear shells are extremely stable. Nuclear physicists are especially interested in nuclei with doubly magic numbers--those that have full shells for both protons and neutrons. One example is the tin isotope Sn-100, which has 50 protons and 50 neutrons. To prepare for future work on Sn-100, researchers studied the properties of isotopes of indium as they approached 50 neutrons. This helps to demonstrate how adding single particles changes the properties of a nucleus.

Nuclear Physicists Create Scalable Quantum Circuits to Simulate Fundamental Physics

Simulations of equations from the Standard Model of particle physics are too difficult for classical supercomputers. In this research, scientists for the first time created scalable quantum circuits to prepare a simulation of the starting state for a particle accelerator collision to test aspects of strong interactions. The researchers first determined these circuits for small systems using classical computers, then scaled the quantum circuits to a large system on more than 100 qubits of IBM's quantum computers.

Scientists Take an Important Step Toward Mitigating Errors in Analog Quantum Simulations of Many-Body Problems

Simulations of quantum many-body problems are a challenge for even the most powerful conventional computers. Quantum computing has the potential to solve this challenge using an approach called an analog quantum simulation. To succeed, these simulations need theoretical approximations of how quantum computers represent many-body systems. In this research, nuclear physicists developed a new framework to analyze these approximations and minimize their effects.

New Analysis Improves Theoretical Understanding of Hyperfine Splitting in Hydrogen

Two experiment collaborations, the g2p and EG4 collaborations, combined their complementary data on the proton's inner structure to improve calculations of a phenomenon in atomic physics known as the hyperfine splitting of hydrogen. An atom of hydrogen is made up of an electron orbiting a proton. The overall energy level of hydrogen depends on the spin orientation of the proton and electron. If one is up and one is down, the atom will be in its lowest energy state. But if the spins of these particles are the same, the energy level of the atom will increase by a small, or hyperfine, amount. These spin-born differences in the energy level of an atom are known as hyperfine splitting.

Scientists can use genetic information to measure if microbes in the environment can perform specific ecological roles. Researchers recently analyzed the genomes of over 6,000 microbial species.

Even Hard Materials Have Soft Spots

The Achilles Heel of "metallic glasses" is that while they are strong materials--even stronger than conventional steels--they are also very brittle. The initial failures tend to be localized and catastrophic. This is due to their random amorphous (versus ordered crystalline) atomic structure. Computer simulations revealed that the structure is not completely random, however, and that there are some regions in the structure that are relatively weak. Defects nucleate more easily in these regions, which can lead to failure. This understanding of the mechanical properties has led to a strategy for making the material stronger and less brittle.

2-D Atoms Do the Twist

In the study, scientists demonstrated, for the first time, an intrinsically rotating form of motion for the atoms in a crystal.

It also means new roles in magnetic, catalytic, or plasmonic materials.

Atomically Packed Boundaries Resist Cracking

A Search for New Superheavy Isotopes

If you chart the stability of atomic cores (nuclei), the trend is that adding more protons and neutrons makes the atom less stable. However, there's an island of stability that bucks this trend. If scientists can provide an easier way of producing elements predicted to be on that island of stability, they can fine-tune today's nuclear models. Such elements were difficult to produce, until a team built an apparatus that efficiently produces superheavy elements by transferring multiple nucleons (either protons or neutrons).

Scientists have identified highly active yet stable catalysts for use in fuel cells that contain only a quarter of the platinum as compared to existing devices. Platinum is essential for promoting reactions in these fuel cells. However, the precious metal is rare and expensive.

Beyond the "Sound Barrier" to Get the Heat Out

To create materials that handle heat well, scientists are exploring how vibrations within the atomic structure carry heat. Atomic vibrations used to remove heat usually are limited by the speed of sound. A new observation may have shattered that limit. A team of scientists observed particles, called phasons, moving faster than the speed of sound that carry heat. The phasons use a pattern of motion in which atoms rearrange themselves, allowing heat to move faster.

Now, they devised a surprisingly simple way of flipping a material from one state into another, and back again, with flashes of light. A single light pulse turns thin sheets of tantalum disulfide from its original (alpha) state into a mixture of alpha and beta states. Domain walls separate the two states. A second pulse of light dissolves the walls, and the material returns to its original state.

After a few days of feeding this microbe sugar, it completely dismantles its photosynthetic apparatus while accumulating fat. In contrast, after the team stopped feeding it sugar, the microbe returned to its normal metabolism.
