Electromagnetic 'swamps' don't always bog electrons down
Scientists have designed a simple system to study how electrons travel through energy barriers instead of over them.
Higgs excitations near absolute zero
(Phys.org) -- A collaboration of physicists from Max Planck Institute of Quantum Optics, LMU, Harvard and Caltech detect Higgs-type excitations in a low-dimensional system of ultracold atoms at the transition ...
No evidence for 'knots' in space
(Phys.org) -- Theories of the primordial Universe predict the existence of knots in the fabric of space - known as cosmic textures - which could be identified by looking at light from the cosmic microwave ...
Reversible doping: Hydrogen flips switch on vanadium oxide
If you are not a condensed matter physicist, vanadium oxide (VO2) may be the coolest material you've never heard of. It's a metal. It's an insulator. It's a window coating and an optical switch. And thanks ...
Graphite enters different states of matter
(Phys.org) -- For the first time, scientists have seen an X-ray-irradiated mineral go to two different states of matter in about 40 femtoseconds (a femtosecond is one quadrillionth of a second).
Swift satellite monitors departing Comet Garradd
(Phys.org) -- An outbound comet that provided a nice show for skywatchers late last year is the target of an ongoing investigation by NASA's Swift satellite. Formally designated C/2009 P1 (Garradd), the unusually ...
Ultrafast sonograms shed new light on rapid phase transitions
An international team of physicists has developed a method for taking ultrafast 'sonograms' that can track the structural changes that take place within solid materials in trillionth-of-a-second intervals ...
Watching a gas turn superfluid
Every time you boil water in a kettle, you witness a phenomenon known as a phase transition — water transforms from a liquid to a gas, as you can see from the bubbling water and hissing steam. MIT physicists ...
Scientists study protein dynamical transitions
(PhysOrg.com) -- Central to life and all cellular functions, proteins are complex structures that are anything but static, though often illustrated as two-dimensional snapshots in time.
Weird world of water gets a little weirder with a new anomaly
Strange, stranger, strangest! To the weird nature of one of the simplest chemical compounds -- the stuff so familiar that even non-scientists know its chemical formula -- add another odd twist. Scientists ...
Batteries get a quick charge with new anode technology
(PhysOrg.com) -- A breakthrough in components for next-generation batteries could come from special materials that transform their structure to perform better over time.
Through the looking glass: physicists solve age-old problem
(PhysOrg.com) -- A problem plaguing physicists across the globe for centuries has finally made a leap towards resolution. The nature of glass has stumped scientists for years but now a researcher from Queen ...
A microscopic view on quantum fluctuations
(PhysOrg.com) -- Scientists at the Max Planck Institute of Quantum Optics achieve direct imaging of quantum fluctuations at absolute zero temperature.
Advanced electron microscope sheds light on metal embrittlement
Why does a solid metal that is engineered for ductility become brittle, often suddenly and with dramatic consequences, in the presence of certain liquid metal impurities?
