Simulations reveal exotic quantum phase transitions in optically trapped superfluid atoms

Phase transitions between different states of matter are normally driven by random thermal motions of atoms. However, when phase transitions occur at temperatures approaching absolute zero, quantum mechanical fluctuations ...

Spanish forest ecosystems' carbon emission will be higher than sequestration

Spanish forest ecosystems will quite probably emit high quantities of carbon dioxide in the second half of the 21st century. This is the conclusion of a report that reviews the results obtained from the implementation of ...

Study demonstrates evolutionary 'fitness' not the most important determinant of success

When you think about evolution, 'survival of the fittest' is probably one of the first things that comes into your head. However, new research from Oxford University finds that the 'fittest' may never arrive in the first ...

Testing an atmospheric model's radiative flux sensitivities at the top of the atmosphere

For the first time, scientists at Pacific Northwest National Laboratory conducted a comprehensive sensitivity study of 16 selected parameters in a popular atmospheric model to analyze their effect on the flux of energy at ...

New method gives accurate picture of gas storage by microscopic cages

A computational method to quantify the adsorption of gas by porous zeolites should help labs know what to expect before they embark upon slow, costly experiments, according to researchers at Rice University.

Numerical validation of quantum magnetic ordering

A new study set out to use numerical simulations to validate previous theoretical predictions describing materials exhibiting so-called antiferromagneting characteristics. A recently discovered theory shows that the ordering ...

Supercomputing the transition from ordinary to extraordinary forms of matter

(Âé¶¹ÒùÔº) —To get a better understanding of the subatomic soup that filled the early universe, and how it "froze out" to form the atoms of today's world, scientists are taking a closer look at the nuclear phase diagram. ...

How often do stars explode as exceptionally bright supernovae?

It is not yet clear what gives rise to supernovae with a peak brightness many times the average, so-called superluminous supernovae (SLSNe), but since they are observable from further away than normal supernovae, a better ...
