A quantum heat engine that simultaneously provides work and refrigeration

The laws of thermodynamics state that heat naturally flows from hotter systems or regions to colder systems or regions until a state of thermal equilibrium is reached. This simple principle underpins the operation of numerous technologies, ranging from refrigerators to power plants.

Rare blue optical transient points to possible new class of cosmic explosion

Chinese astronomers report the detection of a peculiar optical transient event that occurred in the center of a dwarf galaxy. The newly discovered event, designated AT2019ijn, is a fast-rising, slow-decaying blue optical transient with exceptionally bright radio emission. The finding was detailed in a paper published July 6 in The Astrophysical Journal Letters.

Prize honors discovery of altermagnetism as a third fundamental class of magnetism

One of Europe’s highest distinctions in condensed matter physics has been awarded for a discovery that is reshaping our understanding of magnetism: The 2026 Europhysics Prize of the European Physical Society (EPS) Condensed Matter Division goes to Professor Jairo Sinova of Johannes Gutenberg University Mainz (JGU), Dr. Libor Šmejkal and Professor Tomas Jungwirth for their […]

Long-lived ytterbium states could sharpen quantum computing and atomic clocks

Researchers from the University of Amsterdam and the University of New South Wales have answered a question that has been around for decades: whether ions of the metal ytterbium can enter certain long-lived, nearly stable states and, if so, for how long. The measured long-lived states may find applications in quantum computers and atomic clocks. […]

Quantum Zeno effect could freeze computations as qubit systems scale up

The promise of quantum computing is to solve complex problems faster and more energy-efficiently than today’s supercomputers—from optimizing logistics to simulating molecules. This goal is coming within reach as the number of qubits—the computational units of quantum computing—increases.

Magnetic clues inside atomic nuclei help explain how elements form in stars

A scientific team led by Facility for Rare Isotope Beams, or FRIB, has identified the origin of a mysterious excess of low-energy gamma rays emitted by the nucleus zinc-70. They found that the excess is caused by magnetic transitions within the nucleus. The study, “Magnetic Character of the Low-Energy Enhancement in 70Zn,” published in Nature, […]

Why Europa’s hidden ocean may be more difficult to reach than scientists thought

Europa, one of Jupiter’s icy moons, has long fascinated scientists because of what may lie beneath its frozen shell: a global ocean of liquid water. That hidden ocean has made Europa one of the most compelling places in the solar system to study the conditions that might support life. But new research led by Rutgers […]
