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…

Signatures of two- and three-dimensional semimetals from circular dichroism

Ipsita Mandal

Topological invariants are crucial quantities for classifying materials with topological phases. Hence, their connections with experimentally measurable quantities are extremely im…

Floquet transmission in Weyl/multi-Weyl and nodal-line semimetals through a time-periodic potential well

Sandip Bera, Sajid Sekh, Ipsita Mandal

In mesoscopic physics, the application of a time-periodic drive leads to novel transport behaviour, which is absent in the static regimes. Here we consider a quantum pumping protoc…

Magnus Hall effect in three-dimensional topological semimetals

Sajid Sekh, Ipsita Mandal

Magnus Hall effect (MHE) is a non-linear Hall effect requiring no external magnetic field, which can be observed when an in-built electric field couples to the Berry curvature of t…

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…
