Effect of pressure, doping and magnetism on electronic structure and phonon dispersion of FeSe
Abyay Ghosh, Piotr Chudzinski, Myrta Grüning
We present a Density Functional Theory (DFT) based first-principles study on iron chalcogenides superconductor FeSe, systematically investigating pressure and doping induced modifi…

Generalized incommensurability: the role of anomalously strong spin-orbit coupling for the spin ordering in a quasi-2D system, FeSe
Piotr Chudzinski, Abyay Ghosh, Myrta Gruening
We study 2D spin and orbital systems, in a classical limit, in a regime where their coupling is so strong that orbital fluctuations are able to change sign of spin-exchange. Our ai…

Strain-Induced Decoupling Drives Gold-Assisted Exfoliation of Large-Area Monolayer 2D Crystals
Jakob Ziewer, Abyay Ghosh, Michaela Hanušová +5
Gold assisted exfoliation (GAE) is a groundbreaking mechanical exfoliation technique, producing centimeter scale single crystal monolayers of 2D materials. Such large, high quality…
