Amplifying collective light emission with atomic interactions

A team of physicists from the Faculty of Physics at the University of Warsaw, the Center for New Technologies at the University of Warsaw and Emory University (Atlanta, U.S.) analyzed how atoms’ mutual interactions change the way they collectively interact with light.

Researchers pioneer fluid-based laser scanning for brain imaging

When Darwin Quiroz first started working with optics as an undergraduate, he was developing atomic magnetometers. That experience sparked a growing curiosity about how light interacts with matter, an interest that has now led him to a new technique in optical imaging.

Physicists probe quark‑gluon plasma temperatures, helping paint more detailed picture of Big Bang

A research team led by Rice University physicist Frank Geurts has successfully measured the temperature of quark-gluon plasma (QGP) at various stages of its evolution, providing critical insights into a state of matter believed to have existed just microseconds after the Big Bang, a scientific theory describing the origin and evolution of the universe.

Why some quantum materials stall while others scale

People tend to think of quantum materials—whose properties arise from quantum mechanical effects—as exotic curiosities. But some quantum materials have become a ubiquitous part of our computer hard drives, TV screens, and medical devices. Still, the vast majority of quantum materials never accomplish much outside of the lab.

Rigorous approach quantifies and verifies almost all quantum states

Quantum information systems, systems that process, store or transmit information leveraging quantum mechanical effects, could, in principle, outperform classical systems in some optimization, computational, sensing, and learning tasks. An important aspect of quantum information science is the reliable quantification of quantum states in a system, to verify that they match desired (i.e., target) states.

3D-printed metamaterials harness complex geometry to dampen mechanical vibrations

In science and engineering, it’s unusual for innovation to come in one fell swoop. It’s more often a painstaking plod through which the extraordinary gradually becomes ordinary.

Anomalous metal sheds light on ‘impossible’ state between superconductivity and insulation

Researchers at the Niels Bohr Institute, University of Copenhagen, steered very thin conductors from superconductivity to insulation—creating an “impossible,” strange state between the two mutually exclusive states.

Deep blue organic light-emitting diode operates at just 1.5 V

A deep blue organic light-emitting diode (OLED) developed by researchers at Science Tokyo operates on just a single 1.5 V, overcoming the high-voltage and color-purity problems that have long limited blue OLEDs. The breakthrough was achieved by introducing a new molecular dopant that prevents charge trapping, a problem that previously hampered the performance of low-voltage […]

Quantum crystals offer a blueprint for the future of computing and chemistry

Imagine industrial processes that make materials or chemical compounds faster, cheaper, and with fewer steps than ever before. Imagine processing information in your laptop in seconds instead of minutes or a supercomputer that learns and adapts as efficiently as the human brain. These possibilities all hinge on the same thing: how electrons interact in matter. […]

Researchers achieve atomic-scale control of quantum interference

In a study published in Nature Communications, a research team demonstrates the all-electrical control of quantum interference in individual atomic spins on a surface.

Tracking daily commutes with mobile data uncovers urban and rural differences in disease spread

For countless millions across the globe, commuting to work or school is an everyday routine. But during a pandemic, the practice can contribute enormously to the spread of infectious disease, a fact that many traditional metapopulation models often overlook because they are designed primarily for migration and treat people as if they rarely move locally. […]

Direct evidence of universal anyon tunneling in a chiral Luttinger liquid revealed in edge-mode experiment

Electrons in two-dimensional (2D) systems placed under strong magnetic fields often behave in unique ways, prompting the emergence of so-called fractional quantum Hall liquids. These are exotic states of matter in which electrons behave collectively and form new quasiparticles carrying only a fraction of an electron’s charge and obeying unusual quantum statistics.

Twisting sound: Scientists discover a new way to control mechanical vibrations in metamaterial

Scientists at the Advanced Science Research Center at the CUNY Graduate Center (CUNY ASRC) have discovered a way to control sound and vibrations using a concept inspired by “twistronics,” a phenomenon originally developed for electronics.

Uncertainty-aware Fourier ptychography enhances imaging stability in real-world conditions

Professor Edmund Lam, Dr. Ni Chen and their research team from the Department of Electrical and Electronic Engineering under the Faculty of Engineering at the University of Hong Kong (HKU) have developed a novel uncertainty-aware Fourier ptychography (UA-FP) technology that significantly enhances imaging system stability in complex real-world environments. The research has been published in […]
