The International Union of Crystallography (IUCr)‘s Sagamore XIX – 2018: Conference on Quantum Crystallography (QCr), will be held Sunday 8 – Friday 13 July 2018 in Halifax, Nova Scotia, Canada. This is the Official triennial conference of the Commission of Quantum Crystallography of the IUCr.

Under the auspices of the International Union of Crystallography and of Mount Saint Vincent University, and keeping with its tradition, the Sagamore triennial conference (started in 1964) will bring top scientists at the interface of crystallography, material science, quantum and computational chemistry, and solid state physics together in a unique environment that blends theory and experiment, early career and established scientists, and women and visible minorities.

The conference will cover experimental and theoretical research at the interface of physics, chemistry, and biology with the electron charge and spin densities, in both position and momentum space at its center. The overarching theme is the emerging field of “Quantum Crystallography“. The promotion of exchange of ideas and collaborations across the experiment-to-theory divide is an important aim.

Topics range from instrumental advances and new methods in polarized neutron diffraction, X-ray magnetic diffraction (XMD), Compton scattering, time-resolved crystallography, Bader’s Quantum Theory of Atoms in Molecules (QTAIM) and more generally quantum chemical topological (QCT) approaches, with an emphasis on emerging fields such crystals under extreme external conditions of pressure and applied external fields including intense laser field. The conference will touch upon applications of crystallographic and  quantum chemical research in material, drug design, and crystal engineering.

Speakers are strongly encouraged to keep their talks on a rather open and general ground and promote the pedagogical aspects so that a large audience feels welcome to attend, and keep specialized and technical aspects for dedicated poster sessions (and in person side discussions).


Philip Coppens (1930-2017)

It is with great sadness that we have lost in June of 2017 a giant of crystallography and a senior member of this community, Professor Philip Coppens.

Profs. Claude Lecomte, Jason Benedict, and Yu-Sheng Chen have recently Edited a Special Issue of  Acta Cryst. B  entitled  “Charge Density, Photocrystallography and Time-Resolved Crystallography: A Tribute to Professor Philip Coppens”.
