In the fascinating realm of quantum physics, particles seem to defy the laws of classical mechanics, exhibiting mind-bending phenomena that challenge our understanding of the universe. One such phenomenon is quantum tunneling.

In quantum tunnels, particles appear to move faster than the speed of light, seemingly breaking the fundamental rules set by Einstein’s theory of relativity.

However, a group of physicists from TU Darmstadt has proposed a new method to measure the time it takes for particles to tunnel, suggesting that previous experiments may have been inaccurate.

In February, we covered a curious setup that allows you to control digital particles in real time by blowing air into a sensor, created by visual artist Steven Mark Kübler. But what if you had a whole museum of such unusual interactive artworks?

This is what Kübler has been wondering as well. He presented a concept of a room filled with sound paintings manipulated with viewers’ actions. You can see him blowing on the sensor to make particles in a tank-like container splash and part like water. The experience was created using Arduino’s controller and the TouchDesigner visual development platform.

Inflation: The leading theory for the universe’s earliest moments, cosmic inflation, proposes that the universe underwent a brief period of exponential expansion an instant after the Big Bang. This process would have enlarged a minuscule volume of space to a tremendous size, much larger than our observable universe. Inflation neatly explains the flatness and uniformity we observe. But it also suggests that our entire observable universe is a tiny bubble in a vast inflated expanse.

Infinite replicas: If the universe is truly infinite, then everything that occurs within our observable universe must recur an infinite number of times beyond our cosmic horizon. The number of possible particle configurations in any finite volume is large but limited. In an infinite expanse, each configuration, no matter how unlikely, will be realized somewhere, and not just once but an infinite number of times. There would be infinite copies of our observable universe, infinite Milky Way galaxies, infinite Earths, and even infinite versions of you pondering this article. It’s a dizzying but inevitable consequence of an endless cosmos.

Quantum tunneling can explain radioactive decay and also serve applications like microscopy and memory storage.

Scientists have discovered that a “single atomic defect” in a layered 2D material can hold onto quantum information for microseconds at room temperature, underscoring the potential of 2D materials in advancing quantum technologies.

The defect, found by researchers from the Universities of Manchester and Cambridge using a thin material called hexagonal boron nitride (hBN), demonstrates spin coherence—a property where an electronic spin can retain quantum information —under ambient conditions. They also found that these spins can be controlled with light.

Up until now, only a few solid-state materials have been able to do this, marking a significant step forward in quantum technologies.

The NA64 experiment started operations at CERN’s SPS North Area in 2016. Its aim is to search for unknown particles from a hypothetical “dark sector.” For these searches, NA64 directs an electron beam onto a fixed target. Researchers then look for unknown dark sector particles produced by collisions between the beam’s electrons and the target’s atomic nuclei.

Spectroscopy is the study of how matter absorbs and emits light and other radiation. It allows scientists to study the structure of atoms and molecules, including the energy levels of their electrons. Classical optical spectroscopy relies on the way particles of light called photons interact with matter. These classical spectroscopy techniques include one-photon absorption (OPA) and two-photon absorption (TPA).

Quantum information science is truly fascinating—pairs of tiny particles can be entangled such that an operation on either one will affect them both even if they are physically separated. A seemingly magical process called teleportation can share information between different far-flung quantum systems.

A new study unveils the existence of a tetraquark composed of beauty and charm quarks, advancing our knowledge of subatomic particle physics and strong force interactions.

Exploring the complex domain of subatomic particles, researchers at The Institute of Mathematical Science (IMSc) and the Tata Institute of Fundamental Research (TIFR) have recently published a novel finding in the journal Physical Review Letters. Their study illuminates a new horizon within Quantum Chromodynamics (QCD), shedding light on exotic subatomic particles and pushing the boundaries of our understanding of the strong force.
