Physicists report a possibility to "hear" dark matter

Researchers propose a new instrument for the search for axions of dark matter using tunable plasmas. Picture credits: Alexander Millar / University of Stockholm Physicists from the University of Stockholm and the Max Planck Institute for Physics have turned to plasmas in a proposal that could revolutionize the search for the elusive dark matter. Dark matter accounts for 85 percent …

Physicists solve mystery surrounding photon momentum

A photo of the COLTRIMS reaction microscope built by Alexander Hartung as part of his doctoral research in the experiment hall of the Faculty of Physics. Credit: Alexander Hartung              Albert Einstein received the Nobel Prize for explaining the photoelectric effect: in its most intuitive form, a single atom is irradiated with light. According to Einstein, photons that transfer only …

Two physicists are planning where to park your car, Math said

Physicists Paul Krapivsky (Boston University) and Sidney Redner (Santa Fe Institute) decided to use mathematics to answer an age-old question: where to park your car? The criterion? To find the parking lot that minimizes the time spent on the property. LINK: THE RIEMANN HYPOTHESIS: A 160-YEAR-OLD MILLION DOLLAR MATHS PROBLEM Intelligent Decisions "Mathematics allows you to make smart decisions," said …

Physicists at MIT shave the estimate of the mass of neutrino ghost particles in half

An international team of scientists, including researchers at MIT has come closer to establishing the mass of the elusive neutrino. These ghostly particles penetrate the universe and are still considered almost massless. They flow through our bodies millions of times and hardly leave any physical traces. The researchers have determined that the mass of the neutrino should not be more …

Physicists have even better models for blood spatter from gunshot wounds

Enlarge / Dexter may be a (fictitious) serial killer, but he is also a leading expert in the analysis of blood spray patterns. Two new papers could help real-life forensics to better analyze such patterns for investigating crime. YouTube / Showtime With two recent papers, physicists continue to contribute their unique insight into the forensic analysis of blood spatter patterns. …

Physicists make graphene discoveries that could contribute to the development of superconductors

Left: This image, taken with a scanning tunneling microscope, shows a moiré pattern in "magic angle" bilayer graphene. Right: Scanning tunneling charge spectroscopy, a technique invented by the group of Professor Eva Andrei, shows correlated electrons, as shown by the alternating positive (blue) and negative (red) charge stripes formed in the "magic angle" twisted bilayer graph have left.

Physicists count sound particles with quantum microphone

Artistic representation of a series of nanomechanical resonators designed to generate and trap sound particles or phonons. The mechanical movements of the captured phonons are detected by a qubit detector, which shifts its frequency as a function of the number of phonons in a resonator. Different phonon numbers are visible as distinct peaks in the qubit spectrum, which are shown …

The findings of physicists could revolutionize the transmission of information

The picture shows the optical generation of trions in single-layered tungsten diselenide. Picture credits: Erfu Liu, UC Riverside. Move aside, electrons; It's time to make room for the Trion. A research team led by physicists at the University of California, Riverside, has observed, characterized and controlled dark trions in a semiconductor – ultra-pure monolayer tungsten diselenide (WSe 2 – a …
