(Phys.org)—For the first time, scientists have determined the equation of state of an infinite chain of hydrogen atoms, which tells the amount of energy each hydrogen atom has, given the bond length ...

A newly published article in Physical Review Letters eliminates one of the top unsolved theoretical problems in chemical physics as ranked by the National Research Council in 1995. Scientists now can ...

For 50 years, theoretical chemists have puzzled over the problem of predicting many-electron chemistry with only two electrons, which many thought intractable and perhaps impossible to solve. One ...
