Prof. Luiz Santos and his graduate student Jian Wang have proposed a new framework for the realization of topological phase transitions in graphene superlattices. Two-dimensional superlattices, where electrons experience a long length scale periodic potential, have emerged in recent years as versatile platforms to realize exotic forms of quantum matter. A remarkable example of such … More Santos Group Advances Frontier of Topological Phases in Graphene Superlattices

Prof. Urazhdin and collaborators solve the long-standing problem of nonlinear damping in magnetic films. When the amplitude of oscillations in some dynamical systems become large, they start to experience nonlinear relaxation that suppresses large-amplitude dynamics. Among many manifestations of this adverse effect, it has prevented the development of efficient microwave oscillators based on magnetic materials. … More Prof. Urazhdin & collaborators solve the long-standing problem of nonlinear damping in magnetic film
