Finite-size effects in Schulz-Shastry-Luttinger models for determining anyonic signatures in 1d spin chains
B. PerkoviÄ, M. Bonkhoff, T. Posske
We study finite-size properties of Schulz-Shastry-Luttinger liquids to reveal anyonic signatures, realized as low-energy excitations on top of the helical ground state in saturated…
Symmetry and integrability in the anyon-Hubbard model
Martin Bonkhoff, Grennon Gurney, Friethjof Theel +3
Recent cold atom experiments have realized one-dimensional anyons and enabled the tuning of 1D~statistics between bosons and fermions. Here, we analyze the symmetries, integrabilit…
Time-reversal symmetric topological superconductivity in Machida-Shibata lattices
Ioannis Ioannidis, Ching-Kai Chiu, Thore Posske
Recent experiments engineered special spin-degenerate Andreev bound states in atomic cages of adatoms on superconductors, the Machida-Shibata states, a promising building block for…
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…
Hidden Twisted Sectors and Exponential Degeneracy in Root-of-Unity XXZ Heisenberg Chains
Yongao Hu, Felix Gerken, Thore Posske
Recently, product states have been identified as simple-structured eigenstates of XXZ Heisenberg spin models in arbitrary dimensions, occurring at anisotropy values corresponding t…
In-plane ferromagnetism-driven topological nodal-point superconductivity with tilted Weyl cones
Maciej Bazarnik, Levente Rózsa, Ioannis Ioannidis +11
The potential application of topological superconductivity in quantum transport and quantum information has fueled an intense investigation of hybrid materials with emergent electr…
