Unique properties of quantum material explained for first time

This new understanding of the topological material will make it easier for engineers to use it in new applications. OCTOBER 23, 2019 by Steve Tally, Purdue University The characteristics of a new, iron-containing type of material that is thought to have future applications in nanotechnology and spintronics have been determined at Purdue University. The native material, […]

Scientists confirm a new ‘magic number’ for neutrons

 For example, a large energy for the first excited state of a nucleus is indicative of a magic number. OCTOBER 25, 2019 by RIKEN An international collaboration led by scientists from the University of Hong Kong, RIKEN (Japan), and CEA (France) have used the RI Beam Factory (RIBF) at the RIKEN Nishina Center for Accelerator-base Science to show […]

Putting the “bang” in the Big Bang

Physicists simulate critical “reheating” period that kickstarted the Big Bang in the universe’s first fractions of a second. Jennifer Chu | MIT News OfficeOctober 24, 2019 As the Big Bang theory goes, somewhere around 13.8 billion years ago the universe exploded into being, as an infinitely small, compact fireball of matter that cooled as it […]

Surfing on waves in a one-dimensional quantum liquid

OCTOBER 18, 2019 by University of Luxembourg Physicists from the University of Luxembourg, together with international collaborators, have recently published an article in the internationally renowned journal Physical Review Letters. In this article, they demonstrate how quantum-mechanical interference effects could allow experimenters to better study the properties of particles trapped in quantum liquids via resonances in the […]

Manipulating atoms one at a time with an electron beam

New method could be useful for building quantum sensors and computers. David L. Chandler | MIT News Office The ultimate degree of control for engineering would be the ability to create and manipulate materials at the most basic level, fabricating devices atom by atom with precise control. Now, scientists at MIT, the University of Vienna, […]

An ultrafast glimpse of the photochemistry of the atmosphere

OCTOBER 11, 2019 by Max Planck Society Our lives are governed by submicroscopic processes in the nanocosmos. Indeed many natural phenomena begin with a minuscule shift in the states of atoms or molecules, triggered by radiation. One such process has now been elucidated by a team led by Prof. Matthias Kling and Dr. Boris Bergues at […]

Unlocking a 140-year-old secret in physics

In a new study in the journal Nature, an IBM Research-led collaboration describes an exciting breakthrough in a 140-year-old mystery in physics. OCTOBER 11, 2019 by IBM Semiconductors are the basic building blocks of today’s digital, electronic age, providing us a multitude of devices that benefit our modern life, including computer, smartphones and other mobile devices. Improvements […]

Physics researchers break new ground, explore unknown energy regions

OCTOBER 10, 2019 by Kathleen Haughney, Florida State University Florida State University physicists are using photon-proton collisions to capture particles in an unexplored energy region, yielding new insights into the matter that binds parts of the nucleus together. “We want to understand not just the nucleus, but everything that makes up the nucleus,” said FSU Professor […]

Physicists report a way to ‘hear’ dark matter

OCTOBER 9, 2019 by Stockholm University Physicists at Stockholm University and the Max Planck Institute for Physics have turned to plasmas in a proposal that could revolutionise the search for the elusive dark matter. Dark matter makes up 85 percent of the matter in the universe. Originally introduced to explain why the strong force, which holds together […]

Physicists measure the variation of the top-quark mass for the first time

OCTOBER 8, 2019 by Ana Lopes, CERN For the first time, CMS physicists have investigated an effect called the “running” of the top quark mass, a fundamental quantum effect predicted by the Standard Model. Mass is one of the most complex concepts in fundamental physics, which went through a long history of conceptual developments. Mass was first […]
