This symposium will bring together experts in the field of molecular magnetism to define current challenges in this field, examine conditions under which their behaviors transform from classical to quantum, and determine how coherent spin effects arise and break down. In addition to possible qubit and quantum-sensor design, talks aimed at rigorous understanding of field-, photon-, or electron- induced control or interrogation of such systems in chemical, physical and aqueous environs are encouraged as are talks that investigate the role of spin physics in similar naturally occurring functional inorganic molecules and poly-radical biochemical compasses.

The accurate simulation of many electronic phenomena in the condensed phase requires tools with predictive power beyond that of DFT. This Focus Session will bring together researchers working on such techniques for systems with explicit periodicity. Represented approaches will include those based on many-electron wavefunctions, Green's functions, quantum Monte Carlo, and embedding formalisms. Emphasis will be placed on a comparison of the strengths and weaknesses of various methods and collaborative opportunities to advance the field of condensed-phase electronic structure.
