Two UA physicists have discovered that basic concepts such as “hot” or “cold” apply to any system, even those far from equilibrium. Challenging established wisdom, the findings could possibly inform the design of future microelectronic devices and help bring some order around fundamental concepts in thermodynamics. (more…)

So long, solitons: University of Chicago physicists have shown that a group of scientists were incorrect when they concluded that a mysterious effect found in superfluids indicated the presence of solitons—exotic, solitary waves. Instead, they explain, the result was due to more pedestrian, whirlpool-like structures in the fluid. They published their explanation in the Sept. 19 issue of Physical Review Letters. (more…)
Researchers around the world are working on an efficient, reliable way to contain the plasma used in fusion reactors, potentially bringing down the cost of this promising but technically elusive energy source. A new finding from the University of Washington could help contain and stabilize the plasma using as little as 1 percent of the energy required by current methods.
“All of a sudden the current energy goes from being almost too much to almost negligible,” said lead author Thomas Jarboe, a UW professor of aeronautics and astronautics. He presents the findings this week at the International Atomic Energy Association’s 24th annual Fusion Energy Conference in San Diego. (more…)
