Ferrotoroidicity, the fourth form of primary ferroic order, breaks both space and time inversion symmetry. So far, direct observation of ferrotoroidicity in natural materials remains elusive, which impedes the exploration of ferrotoroidic phase trans

Experimental observation of a time rondeau crystal: Temporal Disorder in Spatiotemporal Order

Autor: Moon, Leo Joon Il, Schindler, Paul Manuel, Sun, Yizhe, Druga, Emanuel, Knolle, Johannes, Moessner, Roderich, Zhao, Hongzheng, Bukov, Marin, Ajoy, Ashok

Our understanding of phases of matter relies on symmetry breaking, one example being water ice whose crystalline structure breaks the continuous translation symmetry of space. Recently, breaking of time translation symmetry was observed in systems no

Magnetic topological insulator hosts both a non-trivial surface band and quantum anomalous Hall effect when tuning the time reversal symmetry by various chemical doping into the system. Using molecular beam epitaxy, we have synthesized Bi _2−x Cr _
