Topological properties of spin block magnetic ladders in proximity of a superconductor: application to BaFeS
Shivam Yadav, Pascal Simon, Andrzej Ptok
Monoatomic chains with magnetic order in proximity of a s-wave superconductor can host Majorana edge modes. In this paper, we extend this idea to more complex spin-block chains suc…

Landau levels in Weyl semimetal under uniaxial strain
Shivam Yadav, Andrzej Ptok
The external strain can lead to the similar effect to the external applied magnetic field. Such pseudomagnetic field can be larger than typical magnetic fields, what gives the oppo…

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…
