Observation of a dynamical topological phase transition
Nick Fläschner, Dominik Vogel, Matthias Tarnowski +7
Phase transitions are a fundamental concept in science describing diverse phenomena ranging from, e.g., the freezing of water to Bose-Einstein condensation. While the concept is we…
Helical Floquet Channels in 1D Lattices
Jan Carl Budich, Ying Hu, Peter Zoller
We show how dispersionless channels exhibiting perfect spin-momentum locking can arise in a 1D lattice model. While such spectra are forbidden by fermion doubling in static 1D syst…
Strong Correlation Effects on Topological Quantum Phase Transitions in Three Dimensions
A. Amaricci, J. C. Budich, M. Capone +2
We investigate the role of short-ranged electron-electron interactions in a paradigmatic model of three dimensional topological insulators, using dynamical mean-field theory and fo…
Non-equilibrium Josephson Effect in Atomic Kitaev Wires
C. Laflamme, J. C. Budich, P. Zoller +1
We theoretically study a Kitaev wire interrupted by an extra site which gives rise to super exchange coupling between two Majorana bound states. We show that this system hosts a tu…
