Topology of chalcogen chains
Adam Kłosiński, Wojciech Brzezicki, Alexander Lau +4
We investigate the topological properties of the helical atomic chains occurring in elemental selenium and tellurium. We postulate a realistic model that includes spin-orbit intera…
Non-Hermitian topological quantum states in a reservoir-engineered transmon chain
Wojciech Brzezicki, Matti Silveri, Marcin Płodzień +2
Dissipation in open systems enriches the possible symmetries of the Hamiltonians beyond the Hermitian framework allowing the possibility of novel non-Hermitian topological phases,…
Unprotected edge modes in quantum spin Hall insulator candidate materials
Nguyen Minh Nguyen, Giuseppe Cuono, Rajibul Islam +3
The experiments in quantum spin Hall insulator candidate materials, such as HgTe/CdTe and InAs/GaSb heterostructures, indicate that in addition to the topologically protected helic…
