PandaX sets new constraints on the search for light dark matter via ionization signals
Teams of physicists worldwide have been trying to detect dark matter, an elusive type of matter that does not emit, absorb, or reflect light. Due to its lack of interactions with electromagnetic forces, this matter is very difficult to observe directly, thus most...
New method to search for strongly interacting dark matter inside neutrino detectors
Physicists worldwide are trying to detect dark matter (DM) particles and their interactions with visible matter using various strategies and detectors. As these particles do not emit, reflect or absorb light, they have so far proved to be very difficult to observe,...

Over the past decades, physicists and engineers have been trying to develop various technologies that leverage quantum mechanical effects, including quantum microscopes. These are microscopy tools that can be used to study the properties of quantum particles and...
Study reports melting curve of superionic ammonia under icy planetary interior conditions
Icy planets, such as Uranus (U) and Neptune (N), are found in both our solar system and other solar systems across the universe. Nonetheless, these planets, characterized by a thick atmosphere and a mantle made of volatile materials (e.g., hydrogen water, ammonia,...
A quantum Szilard engine that can achieve two-level system hyperpolarization
Quantum computers, machines that perform computations exploiting quantum mechanical phenomena, could eventually outperform classical computers on some tasks, by utilizing quantum mechanical resources such as state superpositions and entanglement. However, the quantum...
Could quantum gravity models arising from holography explain cosmological acceleration?
Theoretical physicists have long been trying to devise a complete theory of gravity that would also account for quantum mechanics phenomena, as existing models do not. Such a theory could collectively explain the many intricate physical and cosmological phenomena...
A new approach to controlling the properties of turbulence
Turbulence, a fluid motion characterized by chaotic changes in flow velocity and pressure, has been the topic of countless physics studies. Although turbulence is a very common phenomenon that occurs in nature, manipulating it and controlling its properties had so far...
Study reveals the existence of the swallowtail catastrophe in non-Hermitian systems
Researchers from the Hong Kong University of Science and Technology, Xiangtan University and Southern University of Science and Technology recently unveiled a possible connection between catastrophe theory, an area of mathematics that focuses on modeling sudden...
Mapping the curvature where electrons reside in Kagome materials
Kagome metals are a class of quantum materials with interesting properties that are characterized by a unique lattice structure resembling Japanese woven bamboo patterns of the same name (i.e., Kagome). Over the past decade, physicists have been using these materials...
