Understanding the inner workings of the brain has always been a complex task for scientists and researchers. However, a recent study conducted by European scientists has shown promising results in using highly sensitive sensors based on color centers in a diamond to record electrical activity from neurons in living brain tissue. This groundbreaking research opens
The field of heat transfer has traditionally focused on the movement of thermal energy through quantum particles known as phonons. However, recent advancements in nanoscale semiconductors have revealed that phonons alone are not sufficient to efficiently remove heat at such small scales. To address this issue, researchers from Purdue University have turned their attention to
In 1960, Joaquin Luttinger proposed a universal statement that established a relationship between the total number of particles a system can accommodate and its behavior under low-energy excitations. Initially applicable to systems of independent particles, Luttinger’s theorem surprisingly retains its accuracy even in cases of strongly correlated quantum matter where interactions between particles are significant.
Researchers at the University of Cambridge have made a groundbreaking discovery by observing magnetic monopoles in hematite, a material closely related to rust. This finding has the potential to revolutionize computing technologies and pave the way for greener and faster computing systems. Utilizing diamond quantum sensing, the researchers were able to detect faint magnetic signals
Protein research, diagnostics, and analytics rely heavily on the detection, identification, and analysis of macromolecules. Mass spectrometry, a commonly used detection system, helps separate charged particles (ions) and provides valuable information about the composition of a sample. However, conventional detectors have limitations in detecting particles with low-impact energy. An international research team, led by quantum
In a significant step towards revolutionizing the world’s energy landscape, the largest experimental nuclear fusion reactor has officially been inaugurated in Japan. This cutting-edge technology, which aims to fuse atomic nuclei rather than splitting them, holds the promise of being a safe, abundant, and carbon-free source of energy. The JT-60SA reactor, a joint project between
The Wiedemann-Franz law, which states that the ratio of electronic conductivity to thermal conductivity is constant in metals, has been the foundation of understanding electrical and heat conductivity for over 170 years. However, recent experimental findings in quantum materials, where electrons behave collectively rather than individually, have challenged this long-held law. Physicists from the Department
Fluid behavior and the interplay of waves generated by hydraulic jumps have been the focus of a recent study published in Physical Review Letters. The study explores how small water jets can create stable periodic oscillations on a solid disk, shedding light on the dynamic nature of fluid behavior. This phenomenon, known as a hydraulic
Strange metals have long been a subject of intrigue in the realm of quantum physics. In a recent study conducted at Rice University, researchers delved into the elusive nature of these quantum materials by examining quantum charge fluctuations, also known as “shot noise” [1]. The results of this study provide novel evidence that electricity flows
