Colleagues,
With apologies for cross-posting to multiple lists, I would like
to draw your attention to the newly published review article on
cold molecules. The details of the paper are below. The publisher
permits the distribution of only 50 copies so I cannot put the
paper on my webpage but I will be happy to send you a copy by e-mail.
Just let me know if you want one. Alternatively, the pre-print
of the paper can be found on the ArXiv server at
http://www.arxiv.org/abs/physics/0504156
or the paper can be downloaded from the web page of
International Reviews in Physical Chemistry.
Title: Molecules near absolute zero and external field control
of atomic and molecular dynamics
Reference: Int. Rev. Phys. Chem. vol 24, pp. 99-118, 2005
Author: R. V. Krems
Abstract:
This article reviews the current state of the art in the field
of cold and ultracold molecules and demonstrates that chemical
reactions, inelastic collisions and dissociation of molecules
at subkelvin temperatures can be manipulated with external
electric or magnetic fields. The creation of ultracold molecules
may allow for spectroscopy measurements with extremely high
precision and tests of fundamental symmetries of nature,
quantum computation with molecules as qubits, and controlled
chemistry. The probability of chemical reactions and collisional
energy transfer can be very large at temperatures near zero kelvin.
The collision energy of ultracold atoms and molecules is much
smaller than perturbations due to interactions with external
electric or magnetic fields available in the laboratory.
External fields may therefore be used to induce dissociation
of weakly bound molecules, stimulate forbidden electronic
transitions, suppress the effect of centrifugal barriers in
outgoing reaction channels or tune Feshbach resonances that
enhance chemical reactivity.
with regards,
Roman Krems.
