In a new paper by graduate student Aaron Chew, Jason Alicea and IQIM alum David Mross (now at the Weizmann Institute), they discuss “one-dimensional time-crystalline topological superconductors, for which time-translation symmetry breaking and topological physics intertwine—yielding anomalous Floquet Majorana modes that are not possible in free-fermion systems.” In addition to the paper Time-Crystalline Topological Superconductors this work is also featured in the Physics.Org news Time crystals and topological superconductors merge
“The intertwinement between time crystallinity and topological physics generates an interesting twist on excitations that are being pursued for fault-tolerant quantum computing,” [Jason Alicea].
