Higher-order and fractional discrete time crystals in clean long-range interacting systems
Andrea Pizzi, Johannes Knolle, Andreas Nunnenkamp
Discrete time crystals are periodically driven systems characterized by a response with periodicity , with the period of the drive and . Typically, is an integer a…
Electronic properties of α-RuCl3 in proximity to graphene
Sananda Biswas, Ying Li, Stephen M. Winter +2
In the pursuit of developing routes to enhance magnetic Kitaev interactions in α-RuCl3, as well as probing doping effects, we investigate the electronic properties of α-RuCl3 in pr…
Period- discrete time crystals and quasicrystals with ultracold bosons
Andrea Pizzi, Johannes Knolle, Andreas Nunnenkamp
We investigate the out-of-equilibrium properties of a system of interacting bosons in a ring lattice. We present a Floquet driving that induces clockwise (counterclockwise) circula…
Topological magnon amplification
Daniel Malz, Johannes Knolle, Andreas Nunnenkamp
Topology is quickly becoming a cornerstone in our understanding of electronic systems. Like their electronic counterparts, bosonic systems can exhibit a topological band structure,…
