Roderich Moessner

Roderich Moessner is a theoretical physicist at the Max Planck Institute for the Physics of Complex Systems in Dresden, Germany. His research interests are in condensed matter and materials physics, especially concerning new and topological forms of order, as well as the study of classical and quantum many-body dynamics in and out of equilibrium.

Life and career

Moessner studied physics Oxford University, where he was student of Neil Tanner's at Hertford College. At Oxford, he also received his doctorate in theoretical physics under the supervision of John Chalker. After three years as postdoc at Princeton University between 1998 and 2001, he joined the Centre National de la Recherche Scientifique in France, where he did research at the Laboratoire de Physique Théorique at the École normale supérieure, Paris, until 2006. After a faculty appointment at Somerville College and Theoretical Physics at Oxford University, he joined the Max Planck Institute for the Physics of Complex Systems in Dresden as director of the condensed matter division and Scientific Member of the Max Planck Society. Since 2008, he is also honorary professor at TU Dresden.

Research and publications

Moessner's research interests range widely in theoretical condensed matter physics. With Claudio Castelnovo and Shivaji L. Sondhi, Roderich Moessner is known for the theoretical proposition of realizing magnetic monopoles as emergent quasiparticles within a condensed matter system known as spin ice. Other notable results include the theoretical prediction of charge-density wave phases in quantum Hall physics, the identification and theory of a classical spin liquid on the pyrochlore lattice (both with J. T. Chalker); the theoretical discovery of the resonating valence bond liquid phase in the triangular lattice quantum dimer model (with S. L. Sondhi); and the proposal of a new type of spatiotemporal order, the πι-spin glass, now known as discrete time crystal (with V. Khemani, A. Lazarides and S. L. Sondhi), with experimental follow-up work on Google's Sycamore quantum computing platform. He has engaged extensively in experimental collaborations, e.g., on the dynamics of quantum spin liquids or the observation of magnetic monopoles in the material Dy₂Ti₂O₇.

An overview of Roderich Moessner's research articles has been published on his webpage. Most are freely available in preprint form on the arxiv.

Furthermore, together with Joel E. Moore of the University of California, Berkeley, Moessner has published a book on "Topological Phases of Matter", a textbook for use of advanced undergraduates, graduate students, or active researchers. He has also co-edited the lecture notes on topological condensed matter physics of a Les Houches summer school 2014.

Popular culture

Magnetic monopoles in spin ice featured in an episode of The Big Bang Theory not long after the theoretical proposal, while time crystals appeared in an episode of Star Trek: Discovery.
