Investigating the impact of ultralight dark matter on gravitational wave signals

A recent study in Physical Review Letters explores the effects of ultralight dark matter in extreme-mass-ratio inspirals (EMRIs), which could be detected by future space-based gravitational wave detectors like LISA (Laser Interferometer Space Antenna).

Physicists uncover universal non-equilibrium quantum dynamics in randomly interacting spin models

A new study has uncovered the universal dynamics far from equilibrium in randomly interacting spin models, thereby complementing the well-established universality in low-energy equilibrium physics. The study, recently published in Nature Physics, was the result of a collaborative effort involving the research group led by Prof. Du Jiangfeng and Prof. Peng Xinhua at the University […]

Atomic sensors unveil hidden dynamics of molecular polarization

Magnetic resonance imaging (MRI) has long been a cornerstone of modern medicine, providing highly detailed images of internal organs and tissues. MRI machines, those large, tube-shaped magnets commonly found in hospitals, use powerful magnets to map the densities of water and fat molecules within the body.

Decoding top quarks with precision: Experiment at Large Hadron Collider reveals how pairs of top quarks are produced

In collisions between protons at the Large Hadron Collider (LHC), pairs of top quarks—the heaviest known elementary particles—are frequently produced along with other heavy quarks, including bottom and charm quarks. These collision events can provide physicists with valuable insights into quantum chromodynamics (QCD), the theory that describes the strong force. Precisely determining the production rates […]

Tesla-inspired method can control the direction of heat flow in graphite crystals

Researchers from the Institute of Industrial Science, The University of Tokyo, have developed a method to control the direction of heat flow in crystals. This miniature device could eventually be used to create advanced thermal-management systems in electronic devices to prevent overheating.

The neutron lifetime problem—and its possible solution

Neutrons are among the basic building blocks of matter. As long as they are part of a stable atomic nucleus, they can stay there for arbitrary periods of time. However, the situation is different for free neutrons: They decay—after about 15 minutes, on average.

New theoretical framework sets limits for the realization of quantum processes in spacetime

Bell’s theorem, the well-known theoretical framework introduced by John Bell decades ago, delineates the limits of classical physical processes arising from relativistic causality principles. These are principles rooted in Einstein’s theory of relativity, which dictate how cause and effect operate in the universe.

Enhanced wavelength conversion paves the way for more efficient quantum information transfer

Advancements in quantum information technology are paving the way for faster and more efficient data transfer. A key challenge has been ensuring that qubits, the fundamental units of quantum information, can be transferred between different wavelengths without losing their essential properties, such as coherence and entanglement.

Janus-like metasurface technology shows different optical responses according to the direction of light

Metasurface technology is an advanced optical technology that is thinner, lighter, and more capable of precisely controlling light through nanometer-sized artificial structures than conventional technologies. KAIST researchers have overcome the limitations of existing metasurface technologies and successfully designed a Janus metasurface capable of perfectly controlling asymmetric light transmission. By applying this technology, they have also […]

In a fusion device plasma, a steep ion temperature gradient slows the growth of magnetic islands

Future fusion power plants will require good plasma confinement to sustain reactions and generate energy. One way to contain plasma for fusion reactions is to use a tokamak, a device that applies magnetic fields to “bottle” plasma. However, magnetic islands, a type of instability in the plasma, can destroy the confining magnetic field if they […]

Researchers unveil pressure-tuned superconductivity in natural bulk heterostructure 6R-TaS₂

By combining comprehensive high-pressure measurements and first-principles calculations, a research group has discovered the pressure-induced unusual evolution of superconductivity (SC) and exotic interplay between SC and charge-density-wave (CDW) order in a natural bulk van der Waals heterostructure.

Brain delays could be a computational advantage, researchers say

Biological components are less reliable than electrical ones, and rather than instantaneously receive the incoming signals, the signals arrive with a variety of delays. This forces the brain to cope with said delays by having each neuron integrate the incoming signals over time and fire afterwards, as well as using a population of neurons, instead […]
