Machine learning prediction of the convergence criterion for a topological invariant of finite non-Hermitian chains
Raghav Chaturvedi, Viktor Könye, Ewelina M. Hankiewicz
A topological invariant based on polar-decomposition of matrices correctly captures the topology of finite non-Hermitian chains exhibiting the non-Hermitian skin effect, provided t…
Robust Signatures of Fragile Topology
Viktor Könye, Ihor Nimyi, Oleg Janson +3
Some topological phases of matter are called fragile. They do not generically host protected gapless boundary states and they can be trivialized by adding additional valence bands.…
Multipolar Piezoelectricity and Anisotropic Surface Transport in Alterelectrics
Amber Visser, Viktor Könye, Oleg Janson +3
Altermagnets are an emergent class of materials combining features of ferro- and antiferro-magnetic materials. They have spin-separated bands normally associated with ferromagnets,…
