Quantum transition makes electrons behave as if they lack spin

The experimental part, led by Professor Silke Paschen, was conducted in the laboratories of the Vienna University of Technology (TUW) in Austria.  NOVEMBER 14, 2019 by José Tadeu Arantes, FAPESP The common phase transitions are those that occur as a function of temperature variation. Ice changes phase to become liquid water at 0 degrees Celsius. Liquid […]

How do you make the world’s most powerful neutrino beam?

Neutrinos (and their antimatter counterparts, antineutrinos) are born as other particles decay, carrying away small amounts of energy to balance the cosmic ledger.  NOVEMBER 14, 2019 by Lauren Biron, Fermi National Accelerator Laboratory What do you need to make the most intense beam of neutrinos in the world? Just a few magnets and some pencil lead. […]

Etalumis ‘reverses’ simulations to reveal new science

Scientists already have robust simulation software packages that model the physics and everything that occurs within the detector. NOVEMBER 13, 2019 by Keri Troutman, Lawrence Berkeley National Laboratory Scientists have built simulations to help explain behavior in the real world, including modeling for disease transmission and prevention, autonomous vehicles, climate science, and in the search for […]

Massive photons in an artificial magnetic field

During the research, conducted at the University of Warsaw, the unique behavior of photons trapped in the cavity was found as they behaved like mass-bearing quasiparticles.  NOVEMBER 12, 2019 by University of Warsaw An international research collaboration from Poland, the UK and Russia has created a two-dimensional system—a thin optical cavity filled with liquid crystal—in which […]

A distinct spin on atomic transport

NOVEMBER 11, 2019 by ETH Zurich One of the more unexpected things that can be done with charge-neutral atoms is using them to emulate the fundamental behavior of electrons. Over the past few years, the group of Tilman Esslinger at the Institute of Quantum Electronics in the Department of Physics of ETH Zurich has pioneered a […]

Using light to generate order in an exotic material

Physics experiment with ultrafast laser pulses produces a previously unseen phase of matter. David L. Chandler | MIT News OfficeNovember 11, 2019 Adding energy to any material, such as by heating it, almost always makes its structure less orderly. Ice, for example, with its crystalline structure, melts to become liquid water, with no order at […]

Flexible yet sturdy robot is designed to “grow” like a plant

Its extendable appendage can meander through tight spaces and then lift heavy loads. Jennifer Chu | MIT News OfficeNovember 7, 2019 In today’s factories and warehouses, it’s not uncommon to see robots whizzing about, shuttling items or tools from one station to another. For the most part, robots navigate pretty easily across open layouts. But […]

Obtaining order in the “frustrated” landscape of disordered magnetism

NOVEMBER 7, 2019 by Jeremy Rumsey, Oak Ridge National Laboratory Identifying a material’s magnetic structure is a key to unlocking new features and higher performance in electronic devices. However, solving increasingly complex magnetic structures requires increasingly sophisticated approaches. Researchers from the Center for Materials Crystallography at Aarhus University, Denmark, are pioneering a novel technique to solve highly elaborate magnetic structures […]

First magnet installed for the ALPS II experiment at DESY

There are several theories that try to explain the nature of dark matter and the particles it may consist of.  OCTOBER 29, 2019 by Dr. Thomas Zoufal, Deutsches Elektronen-Synchrotron The international ALPS II (“Any light particle search”) collaboration installed the first of 24 superconducting magnets today, marking the start of the installation of a unique particle […]

Mathematics reveals new insights into Marangoni flows

The Marangoni effect is a popular physics experiment. It is produced when an interface between water and air is heated in just one spot. OCTOBER 28, 2019 by Springer The Marangoni effect is a popular physics experiment. It is produced when an interface between water and air is heated in just one spot. Since this heat […]
