Abstract: We consider two-dimensional periodically driven systems of fermions with particle-hole symmetry. Such systems support non-trivial topological phases, including ones that cannot be realized in equilibrium. We show that a space-time defect in the driving Hamiltonian,… read more here.

Abstract: Meetings have become a near-constant presence in the practicing pediatric orthopaedist’s day. While many meetings are productive and efficient, others may represent a time vortex that take precious hours away from other meaningful pursuits. Organizers… read more here.
