Ultra-high speed camera for molecules: Attosecond spectroscopy captures electron transfer dynamics

In nature, photosynthesis powers plants and bacteria; within solar panels, photovoltaics transform light into electric energy. These processes are driven by electronic motion and imply charge transfer at the molecular level. The redistribution of electronic density in molecules after they absorb light is an ultrafast phenomenon of great importance involving quantum effects and molecular dynamics. […]

First observation of ultra-rare particle decay could uncover new physics

Scientists at CERN have discovered an ultra-rare particle decay process, opening a new path to find physics beyond our understanding of how the building blocks of matter interact.

Team studies the emergence of fluctuating hydrodynamics in chaotic quantum systems

Researchers at Ludwig-Maximilians-Universität, Max-Planck-Institut für Quantenoptik, Munich Center for Quantum Science and Technology (MCQST) and the University of Massachusetts recently carried out a study investigating the equilibrium fluctuations in large quantum systems. Their paper, published in Nature Physics, outlines the results of large-scale quantum simulations performed using a quantum gas microscope, an experimental tool used […]

New physics needed? Experts suggest possibility of updating fundamental physics concepts

An unexpected finding about how our universe formed is again raising the question: do we need new physics? The answer could fundamentally change what physics students are taught in classes around the world.

Physicists use quantum correlations of photon pairs to hide images from standard cameras

What if you could hide an image in plain sight—so well that even the most advanced cameras couldn’t detect it? Imagine encoding visual information using the properties of quantum optics, rendering it invisible to normal imaging technology.

Controlling light while measuring trapped ion qubits

Quantum information is fragile and often difficult to protect during experiments. Protecting qubits from accidental measurements is essential for controlled quantum operations, especially during state-destroying measurements or resets on adjacent qubits in protocols like quantum error correction.

New results from the CMS experiment put W boson mass mystery to rest

After an unexpected measurement by the Collider Detector at Fermilab (CDF) experiment in 2022, physicists on the Compact Muon Solenoid experiment (CMS) at the Large Hadron Collider (LHC) announced today a new mass measurement of the W boson, one of nature’s force-carrying particles.

Researchers observe an antiferromagnetic diode effect in even-layered MnBi₂Te₄

Antiferromagnets are materials in which the magnetic moments of neighboring atoms are aligned in an alternating pattern, resulting in no net macroscopic magnetism. These materials have interesting properties that could be favorable for the development of spintronic and electronic devices.

Even the heaviest particles experience the usual quantum weirdness, new experiment shows

One of the most surprising predictions of physics is entanglement, a phenomenon where objects can be some distance apart but still linked together. The best-known examples of entanglement involve tiny chunks of light (photons), and low energies.

Preparing the LHC and its injector complex for the 2024 lead-ion run

In the early morning of 13 September, the LHC reached a significant milestone, surpassing 100 fb-1 of integrated luminosity delivered to ATLAS and CMS in a single year—a record—and the figure is still rising. Then, LHCb’s integrated luminosity target of 8.5 fb-1 was reached one day later.

New material with wavy layers of atoms exhibits unusual superconducting properties

MIT physicists and colleagues have created a new material with unusual superconducting and metallic properties, thanks to wavy layers of atoms only billionths of a meter thick that repeat themselves over and over to create a macroscopic sample that can be manipulated by hand. The large size of the sample makes it much easier to […]
