Immediately after the Big Bang, which occurred around 13.8 billion years ago, the universe was dominated by unimaginably high temperatures and densities. However, after just a few seconds, it had cooled down enough for the ...
Perovskite is a rising star in the field of materials science. The mineral is a cheaper, more efficient alternative to existing photovoltaic materials like silicon, a semiconductor used in solar cells. Now, new research has ...
Quantum sensing has transformational potential across many areas of technology and science, most prominently biomedical research. The basic premise is to detect and manipulate the spin state of an electron—magnetic properties ...
Quantum field theory (QFT) is a physics framework that describes how particles and forces behave based on principles rooted in quantum mechanics and Albert Einstein's special relativity theory. This framework predicts the ...
Known for their ability to seamlessly integrate into semiconductor chips, VCSELs (vertical cavity surface-emitting lasers) are used in everything from computer mice to face-scanning hardware in smartphones. However, these ...
As technology advances, photonic systems are gaining ground over traditional electronics, using light to transmit and process information more efficiently. One such optical system is laser beam scanning (LBS), where laser ...
As the demand for more secure data transmission increases, conventional communication technologies are facing limitations imposed by classical physics, and are therefore approaching their limits in terms of security. Fortunately, ...
Ghost imaging is like a game of Battleship. Instead of seeing an object directly, scientists use entangled photons to remove the background and reveal its silhouette. This method can be used to study microscopic environments ...
Usually, light waves can pass through each other without any resistance. According to the laws of electrodynamics, two light beams can exist in the same place without influencing each other; they simply overlap. Light saber ...
Neutrinos are subatomic particles with no charge and very little mass that are known to weakly interact with other matter in the universe. Due to their weak interactions with other particles, these particles are notoriously ...
