Local Topological Markers in Odd Spatial Dimensions and Their Application to Amorphous Topological Matter
Julia D. Hannukainen, Miguel F. Martinez, Jens H. Bardarson +1
Local topological markers, topological invariants evaluated by local expectation values, are valuable for characterizing topological phases in materials lacking translation invaria…
Dephasing enhanced strong Majorana zero modes in 2D and 3D higher-order topological superconductors
Loredana M. Vasiloiu, Apoorv Tiwari, Jens H. Bardarson
The 1D Kitaev model in the topological phase, with open boundary conditions, hosts strong Majorana zero modes. These are fermion parity-odd operators that almost commute with the H…
Non-Hermitian topology in monitored quantum circuits
Christoph Fleckenstein, Alberto Zorzato, Daniel Varjas +3
We demonstrate that genuinely non-Hermitian topological phases and corresponding topological phase transitions can be naturally realized in monitored quantum circuits, exemplified…
