Tunable quantum behavior observed in bilayer graphene
Columbia researchers have observed the fractional quantum Hall effect in bilayer graphene and shown that this exotic state of matter can be tuned by an electric field.
A counterintuitive phenomenon discovered: The coexistence of superconductivity with dissipation
For his doctoral dissertation in the Goldman Superconductivity Research Group at the University of Minnesota, Yu Chen, now a postdoctoral researcher at UC Santa Barbara, developed a novel way to fabricate ...
Scientists find way to maintain quantum entanglement in amplified signals
Physicists Sergei Filippov (MIPT and Russian Quantum Center at Skolkovo) and Mario Ziman (Masaryk University in Brno, Czech Republic, and the Institute of Physics in Bratislava, Slovakia) have found a way ...
Exotic state of matter propels quantum computing theory
So far it exists mainly in theory, but if invented, the large-scale quantum computer would change computing forever. Rather than the classical data-encoding method using binary digits, a quantum computer would process information ...
Physicists succeed in revealing the scaling behaviour of exotic giant molecules
When a two-body relation becomes a three-body relation, the behaviour of the system changes and typically becomes more complex. While the basic physics of two interacting particles is well understood, the ...
Highly charged ions: Multiply-ionized atoms for clocks, qubits, and constants
The world is mostly neutral. That is, most of the atoms in our environment are electrically neutral. The number of electrons in the outer parts of atoms equals the number of protons at the centers of atoms. ...
The bend in the Appalachian mountain chain is finally explained
The 1500 mile Appalachian mountain chain runs along a nearly straight line from Alabama to Newfoundland—except for a curious bend in Pennsylvania and New York State. Researchers from the College of New ...
Germany most energy efficient nation
Germany is the world's most energy efficient nation with strong codes on buildings while China is quickly stepping up its own efforts, an environmental group said Thursday.
Most NSA data from regular Internet users, report says (Update)
Nine out of 10 people identified in a large cache of online conversations intercepted by the National Security Agency were ordinary Internet users and not foreign surveillance targets, a news report says.
Why does Europe hate GM food and is it about to change its mind?
While the United States, Canada, Brazil, Argentina and China and many other countries have warmly embraced genetically modified crops, Europe remains the world's big holdout.
Obama salutes 45th anniversary of US astronauts' Moon landing
Celebrating the 45th anniversary of the first lunar landing, President Barack Obama on Tuesday recognized the "courage" of astronauts Neil Armstrong, Buzz Aldrin, and Michael Collins, who participated in ...
Netflix tops 50M subscribers as 2Q earnings soar (Update)
Netflix's second-quarter earnings more than doubled as new episodes from a hit series helped the Internet video service surpass 50 million worldwide subscribers for the first time.
Research finds bedbugs can be killed with lower dosage of chemical
A recent change to bedbug fumigation will make it more cost-effective to get rid of the pests, thanks to research from Kansas State University.
Mexico reports first litter of wolf cubs in the wild
The first known litter of Mexican gray wolves has been born in the wild as part of a three-year effort to re-introduce the subspecies to a habitat where it disappeared three decades ago, Mexican officials reported Thursday.
