Flatiron Research Fellow - Software, Center for Computational Quantum Physics

About the role

Directed by Antoine Georges and co-directed by Andrew Millis, the Center for Computational Quantum Physics (CCQ) is a leading international center for the study of equilibrium and non-equilibrium many-body quantum systems, with applications to condensed matter physics, materials science, quantum materials, quantum emulators and related fields. The development of the concepts, algorithms and code libraries needed to advance the field is fundamental to the work of the center. Research projects currently pursued at CCQ cover a broad range of methods and interest, see: https://www.simonsfoundation.org/flatiron/center-for-computational-quantum-physics/ CCQ currently comprises more than 40 scientists at career stages from recent Ph.D.s through senior scientists, as well as support staff, visiting scientists, and affiliated graduate students and interns. The institute has vigorous visitor and workshop programs and strong interactions with scientists from neighboring institutions. CCQ has established formal partnerships with the New York City-Max Planck Center for Non-Equilibrium Quantum Phenomena, the CIFAR Quantum Materials program, the QUAST collaboration, the CEA-France, and the Collège de France and collaborates extensively with scientists at a range of institutions in the US and internationally. Candidates interested in collaborative work or joint positions are encouraged to discuss possibilities with CCQ staff. A core effort at CCQ is the development of open-source software libraries with the latest algorithms and tools for advancing scientific research at CCQ and across the wider scientific community. Major software efforts at CCQ include the TRIQS library for quantum embedding, the AFQMC library for auxiliary-field quantum Monte Carlo and the ITensor library for tensor network algorithms. The Flatiron Research Fellow-Software position is at a postdoctoral level and has as a primary focus the design and implementation of software relevant to research at CCQ. Fellows primarily develop and expand one of the major code efforts at CCQ, devise new or improved algorithms, and advance fundamental research through the perspective of software design and optimization. Applicants typically have backgrounds in one or more of the following areas: theoretical condensed matter physics, computational physics, materials science, theoretical or computational chemistry, applied mathematics, and computer science. Fellows in this highly collaborative position are expected to disseminate their results through a combination of open-source software development, participation in conferences, workshops and seminars, some publications in the scientific literature, and through mentorship of undergraduate and graduate students as appropriate. CCQ also anticipates making several Flatiron Research Fellow appointments; these positions are for scientists who work on developing new concepts, algorithms, and codes needed to understand the many-particle quantum problem, and on the physical and chemical properties of systems requiring this new understanding. The initial appointment is generally for two years, with the possibility of renewal for a third year, contingent on performance. Flatiron Software Fellows may be eligible for subsidized housing within walking distance of the CCQ. The anticipated start date is between end of August 2027 through early November 2027.
