Kagome edge states under lattice termination, spin-orbit coupling, and magnetic order
Sajid Sekh, Annica M. Black-Schaffer, Andrzej Ptok
We study the edge state properties of a two-dimensional kagome lattice using a tight-binding approach, focusing on the role of lattice termination, spin-orbit coupling, and magneti…
Electronic and magnetic properties of the NdNiO/SrTiO thin films
Sajid Sekh, Andrzej Ptok, Wojciech Brzezicki +2
The hole-doped NdNiO layer deposited on the SrTiO surface exhibits unconventional superconductivity. Here, we present a systematic study of the electronic and magnetic pr…
Topological in-gap chiral edge states in superconducting Haldane model with spin-orbit coupling
Sajid Sekh, Andrzej Ptok
Topological superconductivity is currently one of the prime interests, given the properties of its exotic nature of chiral edge states. A broken time-reversal symmetry (TRS) is an…
Low temperature phase of AuSn induced by the van der Waals interactions
Shivam Yadav, Sajid Sekh, Andrzej Ptok
AuSn is the example of an compound that exhibits topological properties. Recent XRD measurements reveal an ambiguous nature of the crystal structure, as it can be realized wi…
Circular dichroism as a probe for topology in three-dimensional semimetals
Sajid Sekh, Ipsita Mandal
Higher-pseudospin fermions, associated with multiple band-crossings in topological semimetals, are the condensed matter analogues of higher-spin fermions in high-energy physics. In…
