Universal Topological Power Transfer with Arbitrarily Large Chern Number in Driven Quantum Spin Chains
Anshuman Tripathi, Mircea Trif, Thore Posske
Topological frequency converters exploit a quantized transfer of power between two driving fields in a quantum system, a phenomenon topologically protected by the Chern number of t…
The toric code under antiferromagnetic isotropic Heisenberg interactions
Won Jang, Robert Peters, Thore Posske
We investigate the impact of an isotropic antiferromagnetic Heisenberg perturbation on the toric code, focusing on the resulting quantum phase transition and the nature of the phas…
Microscopic origin of Rashba coupling from first principles: Layer-resolved orbital asymmetry in transition metal dichalcogenides
Miguel Morales Cócera, Marta Prada, Franz Fischer +1
Spin-orbit coupling in two-dimensional materials gives rise to a Rashba spin splitting when inversion and mirror symmetries are broken, yet its microscopic origin and quantitative…
Disorder-Induced Topological Phases in a Two-Dimensional Chern Insulator with Strong Magnetic Disorder
Devesh Vaish, Michael Potthoff
Strong directional disorder in local magnetic moments coupled to a Chern insulator gives rise to topological phases that cannot be continuously connected to the clean limit and are…
Two-Body Kapitza-Dirac Scattering of One-Dimensional Ultracold Atoms
André Becker, Georgios M. Koutentakis, Peter Schmelcher
Kapitza-Dirac scattering, the diffraction of matter waves from a standing light field, is widely utilized in ultracold gases, but its behavior in the strongly interacting regime is…
Unconventional bright ground-state excitons in monolayer TiI from first-principles calculations
Franz Fischer, Carl Emil Mørch Nielsen, Marta Prada +1
Based on \textit{ab initio} screened configuration interaction calculations we find that TiI has a bright exciton ground state and identify two key mechanisms that lead to this…
