The thermal hall effect (THE) is a mysterious physical phenomenon that arises when a material is subjected to a thermal current and a perpendicular magnetic field, leading to tiny transverse temperature differences. Despite being observed in various insulators, the underlying physics of this effect remains poorly understood. Researchers at Université de Sherbrooke in Canada have
For many years, the scientific community believed that amorphous solids lacked the ability to selectively absorb light due to their disordered atomic structure. However, a recent study conducted at the University of Ottawa has challenged this long-standing theory. Researchers at uOttawa have discovered that amorphous solids exhibit dichroism, meaning they can selectively absorb light of
In a groundbreaking development in the field of electrical engineering, a research team led by Professor Wang Cheng from the Department of Electrical Engineering (EE) at City University of Hong Kong (CityUHK) has created a cutting-edge microwave photonic chip capable of ultrafast analog electronic signal processing and computation using optics. This chip, which is significantly
Topological wave structures have captured the interest of physicists for their unique properties that remain unchanged under smooth deformations of a physical system. While these structures have been extensively studied in various wave systems, one area that has surprisingly been neglected is water waves. A recent study by researchers at RIKEN aims to fill this
The energy generated by the sun and other stars is a result of a series of nuclear fusion reactions. These reactions culminate in the fusion of protons with beryllium-7 to produce boron-8. Understanding these processes is crucial in determining the flow of high-energy solar neutrinos that reach our planet. However, replicating the low-energy conditions of
In today’s fast-paced world, the ability to solve intricate problems efficiently is more critical than ever. Traditional computers often face challenges when dealing with a high volume of interconnected variables, leading to inefficiencies such as the von Neumann bottleneck. However, a new paradigm in problem-solving has emerged in the form of collective state computing, which
The universe is filled with mysteries that scientists have been trying to unravel for centuries. One such mystery is the complex relationship between gravity and the quantum world. While Isaac Newton first discovered the force of gravity, it has remained a puzzle on a microscopic level. Even Albert Einstein, in his theory of general relativity,
In the realm of scientific research, one topic that has long captured the imagination of physicists and the public alike is antimatter. Among the various experiments conducted in this field, the AEgIS project at CERN’s Antimatter Factory stands out for its groundbreaking work in producing and studying antihydrogen atoms. The process of creating antihydrogen within
Semiconductor materials play a crucial role in various optoelectronic applications such as solar cells, transistors, detectors, sensors, and LEDs. Understanding the transport properties of both negative and positive charge carriers in semiconductors is essential for optimizing the performance of these devices. Traditionally, determining these properties required separate measurements for each type of charge carrier, leading
