Observing a prethermal discrete time crystal

A framework of statistical physics can be extended to the nonequilibrium setting to discover previously unidentified phases of matter catalyzed by periodic driving. Scientists aim to reduce the runaway heating associated with driving a strongly interacting quantum system in order to investigate newly discovered phases.

Physicists use electric fields to induce oscillations in tiny particles

A challenging frontier in science and engineering is controlling matter outside of thermodynamic equilibrium to build material systems with capabilities that rival those of living organisms. Research on active colloids aims to create micro- and nanoscale "particles" that swim through viscous fluids like primitive microorganisms. When these self-propelled particles come together, they can organize and move like schools of fish to perform robotic functions, such as navigating complex environments and delivering "cargo" to targeted locations.

How physics breaks down in a black hole

One of the most cherished laws of physics—the conservation of charge—has come under fire in "startling" research by physicists.

The fifth quartet: Excited neon discovery could reveal star qualities

Scientists from the Department of Physics and the Research Center for Nuclear Physics (RCNP) at Osaka University, in collaboration with Kyoto University, used alpha particle inelastic scattering to show that the theorized "5α condensed state" does exist in neon-20. This work may help us obtain a better understanding the low-density nucleon many-body systems.

Theoretical proof that a strong force can create lightweight subatomic particles

Using only a pen and paper, a theoretical physicist has proved a decades-old claim that a strong force called Quantum Chromo Dynamics (QCD) leads to light-weight pions, reports a new study published on June 23 in Physical Review Letters.

Mechanism behind XFEL-induced melting of diamond unveiled

The ultrafast melting of diamond under intense x-ray irradiation has been visualized for the first time by RIKEN researchers. This observation will help scientists improve experimental methods that use high-intensity x-ray pulses to determine the structures of materials.

Quantum simulation: Measurement of entanglement made easier

University of Innsbruck researchers have developed a method to make previously hardly accessible properties in quantum systems measurable. The new method for determining the quantum state in quantum simulators reduces the number of necessary measurements and makes work with quantum simulators much more efficient.

Calibration method enables microscopes to make accurate measurements in all 3 dimensions

Conventional microscopes provide essential information about samples in two dimensions—the plane of the microscope slide. But flat is not all that. In many instances, information about the object in the third dimension—the axis perpendicular to the microscope slide—is just as important to measure.

A high-resolution microscope built from LEGO and phone bits

Microscopy is an essential tool in many fields of science and medicine. However, many groups have limited access to this technology due to its cost and fragility. Now, researchers from the Universities of Göttingen and Münster have succeeded in building a high-resolution microscope using nothing more than children's plastic building bricks and affordable parts from a mobile phone. They then went on to show that children aged nine to 13 had significantly increased understanding of microscopy after constructing and working with the LEGO microscope. Their results were published in The Biophysicist.

Rearranging orchestral musicians to reduce disease-spreading aerosols

A team of researchers at the University of Utah Salt Lake City has found, via simulation, that it is possible to rearrange musicians playing wind instruments in an orchestra to reduce the spread of disease-laden aerosols. In their paper published in the journal Science Advances, the group describes simulations they ran that showed airflow patterns during orchestral performances and what they found.

Researchers resolve magnetic structures of different topological semimetals

Topological semimetals are one of the major discoveries in condensed-matter physics in recent years. The magnetic Weyl semimetal, in which the Weyl nodes can be generated and modulated by magnetization, provides an ideal platform for the investigation of the magnetic field-tunable link between Weyl physics and magnetism. But due to the lack of appropriate or high quality specimens, most of the theoretically expected magnetic topological semimetals have not been experimentally confirmed. Therefore, exploration of new magnetic topological semimetals is of great importance.

Scientists present new measurements of β-delayed two-proton decay of 27S

Two-proton decay is a quantum tunneling process. The tunneling probability depends on the available energy and the height of the Coulomb barrier, which in turn depends on the nuclear charge Z (number of protons). Two-proton emission is a typical three-body breakup process, including the daughter nucleus and two protons, in which pairing correlations play an important role. Therefore, a detailed study of two-proton emission is of great significance for exploring the open quantum system, pairing correlations and exotic nuclear structure.

Artificial intelligence speeds forecasts to control fusion experiments

Machine learning, a technique used in the artificial intelligence (AI) software behind self-driving cars and digital assistants, now enables scientists to address key challenges to harvesting on Earth the fusion energy that powers the sun and stars. The technique recently empowered physicist Dan Boyer of the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) to develop fast and accurate predictions for advancing control of experiments in the National Spherical Torus Experiment-Upgrade (NSTX-U)—the flagship fusion facility at PPPL that is currently under repair.

A simple method to enhance responsivity of terahertz radiation detectors

Scientists of Tomsk Polytechnic University jointly with colleagues from Spanish universities have offered a simple method how to enhance the responsivity of terahertz radiation detectors by 3.5 times using a small Teflon cube. The 1 mm cube must be put on the surface of the detector without changing the inner design of the detector.

Astronomy and Space news

Cosmic dawn occurred 250 to 350 million years after Big Bang

Cosmic dawn, when stars formed for the first time, occurred 250 million to 350 million years after the beginning of the universe, according to a new study led by researchers at University College London (UCL) and the University of Cambridge.

Astrophysicists prepare for age of multi-messenger astronomy, build galaxy catalog to study black holes

Led by postdoctoral fellow researcher Maria Charisi, a team of international researchers known as the NANOGrav collaboration has created a catalog of 45,000 galaxies to detect gravitational waves created by pairs of black holes known as binaries. Using pulsars—the most precise clocks of the sky—a galactic scale detector dubbed a pulsar timing array and infrared data from across the sky, Charisi used the catalog to input hypothetical binaries to measure differences in the masses of the two black holes or their distance from each other within a galaxy. "Since we haven't found gravitational waves with pulsar timing arrays yet, we can play with our binary parameters and a range of gravitational wave frequencies to find the limits of the sizes of black hole binaries in specific galaxies," Charisi said.

Motions of a remarkable cosmic structure have been measured for the first time, using NASA's Chandra X-ray Observatory. The blast wave and debris from an exploded star are seen moving away from the explosion site and colliding with a wall of surrounding gas.

Research looks to outer space to learn about human health on Earth
