ON THE EFFECTIVE EQUATION OF STATE OF DARK ENERGY [PDF]
International Journal of Modern Physics D, 2010 In an effective field theory model with an ultraviolet momentum cutoff, there is a relation between the effective equation-of-state of dark energy and the ultraviolet cutoff scale. It implies that a measure of the equation of state of dark energy different from minus one, ω ≠ -1, does not rule out vacuum energy as dark energy.

Energy states and energy flow near the transition states of unimolecular reactions [PDF]
, 1994 The use of lasers with jet-cooled samples has improved energy and angular momentum resolution for the reactant and time resolution for the rate constant by orders of magnitude. The resolution of product quantum states has added a new dimension to unimolecular dynamics.
